Skiff is excited to announce our integration between Unstoppable Domains and Skiff Mail. Earlier this month, Skiff announced a new way to sign up for a Skiff account using your Unstoppable Domain.

Right now, creating a Skiff account means choosing a new email address (@skiff.com), signing up with a wallet with your public wallet address as your username, or logging in with your Unstoppable Domains account.

We’re now taking it one step further and enabling Unstoppable owners to use @ud.me inside of Skiff Mail.

What does this mean? It means that Unstoppable owners get access to a free end-to-end encrypted email that protects their inbox and gives them the power to communicate freely. In the digital era, we keep our lives in our inboxes. Skiff Mail’s end-to-end encryption keeps your mail private and secure. No one — not big tech, not us, not anyone — has access but you.

With 2.5 million registered domains in the Unstoppable ecosystem, Skiff Mail becomes the simplest and most private solution for UD users to communicate, enabling a communication layer in Web3 that was impossible - until now.

For Unstoppable owners who are new to the Skiff ecosystem, 

If you already have a Skiff account, you can still connect your Unstoppable Domain in the settings page of your Skiff Mail inbox.

Communicate and collaborate. All in one place.

In addition to an email address, Skiff Mail account gives you access to the first-ever end-to-end encrypted productivity suite. Jump from docs to email, to remote collaboration. And never compromise your privacy in the process.

 - letting users access end-to-end encrypted documents and data on Skiff using an existing keypair (an Ethereum address).

We’ve been extremely excited by the volume of support and positive feedback for this feature - from new users who now have a seamless way to get started with Skiff, to veteran users excited by the prospect of self-custody of their keys.

Today, we’re rolling out an all-new way for Skiff users to benefit from an existing Ethereum address: Users can now use an Ethereum Naming Service (ENS) name to streamline display name creation and doc sharing on Skiff.

ENS is an open-source, Ethereum-based naming protocol designed to offer a decentralized, Web3 alternative to the internet’s traditional naming system, DNS. While DNS maps human-readable domain names to IP addresses, ENS does the same for Ethereum addresses, wallet addresses and other machine-readable identifiers. As a result, ENS empowers people to manage custody of their own named online assets and easily carry them from one service to another.

Skiff’s support for ENS breaks down into two components:

When you sign up with a wallet associated with an ENS address, Skiff will look up your Ethereum address (reverse lookup), check the corresponding ENS name (forward lookup), and then set your ENS name as your display name.

Of course, some people may opt not to use their ENS name as their display name. Display names for all Skiff users can be changed or removed at any time. But even if you decide not to use an ENS name as your display name, your ENS name can still be used for sharing docs!

The ENS name of any Skiff user who’s connected their Metamask wallet can now be used to share docs with them — even if they haven’t set a display name.

To share with someone via their ENS name, just type in the ENS name to Skiff’s doc-sharing interface and set permissions as usual. Skiff will look up the name (reverse lookup), convert it to the corresponding Ethereum address, and then share the document to their Skiff account via this address.

Skiff is already hard at work on many more new features, which, like our support for ENS, will give users greater control over their data and easier access to secure, private collaboration. Watch this space or follow us 

Skiff x Ethereum Naming

We at Skiff want to make privacy effortless

 for everyone. That’s why we’re so excited to be sharing this post about end-to-end encryption (E2EE) and our product.

Keep your work private with end-to-end encryption

 helps people communicate without revealing the contents of their messages to anyone in between, including the service provider. Skiff uses E2EE not only for messaging, but also for all writing, collaboration, and communication on our platform, including documents, comments, titles, messages, and more. Encryption keys are only known to our users, and not to us.

Today, many products we use for remote work and collaboration - including messaging, note-taking, and video conferencing - take only superficial measures when it comes to protecting your data and privacy. Recently, however, E2EE has become the expected standard for messaging: From iMessage and WhatsApp, to Signal and Telegram, billions of people are using end-to-end encrypted messengers (we certainly hope you are!). These messaging products end-to-end encrypt all communications by default, keeping content and personal data private from service providers.

Yet, there are so many other services beyond messaging apps that could benefit from the high level or privacy and security provided by E2EE. The reason Amazon, Microsoft, Google, and Apple have not been able to make the full switch is that privacy - and particularly end-to-end encryption - must be built into products from the ground-up. It requires designing authentication algorithms, distributing public keys and private keys to users, and intentionally designing software that collects less personal information and metadata. When products are built without these technical requirements in mind, it's hard for a product to pivot and distribute encryption keys to every user, stop collecting individuals' personal information, and start to encrypt all communications and data on the platform.

Skiff is building E2EE as a core design principle for all parts of online work. A lot of the work you do online can be become sensitive at the drop of a dime, and you shouldn’t have to be constantly adapting to different products. In years past, using end-to-end encryption required keeping track of personal encryption keys (such as PGP keys) or pasting messages into encryption platforms or complex command line tools. Today, privacy can and must be built-in from the start as the basis of every product we use.

Below, we have a simplified diagram illustrating the workings of a collaboration platform that, like most of today’s dominant providers, 

 use E2EE. The diagram illustrates how changes made to a shared document by one user (“Bob”) are made available to a second user (“Alice”).

Bob, pictured on the far left, makes an edit on the document. Bob sends the edits 

 to the service provider's server (Note: The data may be encrypted over the network connection from Bob to the server using HTTPS). After Bob logs in, the server receives his edit and merges it into the document. Now, Alice - another collaborator on the document - is sent a copy of the new version of the document with Bob’s changes. In this process, the technology provider has access to everything Bob writes and the entire document. In some cases, this data is fed in to providers' monetization or prediction algorithms.

In this second diagram, we share Skiff's version. Bob makes an edit, and - before sending it to the provider - encrypts it with a symmetric encryption key shared 

 between him and Alice (and never shared with Skiff). Alice then receives Bob's encrypted edit, performs validation and decryption, and subsequently merges it into the document.

In the Skiff E2EE case, however, Alice and Bob's document is kept private to the intended recipients and never exposed to any central technology provider. In this way, data ownership is decentralized and private to the two editors Alice and Bob, as it should be. The first case requires that Alice and Bob trust that service provider's databases, endpoints, and servers are protected from data breaches, misuse, and cyberattacks. In the second (E2EE) case, Skiff case adds a layer of encryption to their private information that is unbreakable by the technology provider. The Skiff model is how all consumer technology should be built - even if you're not protecting sensitive healthcare or financial data (and you just prefer privacy).

The Skiff model doesn't just keep Alice and Bob's diary for their eyes only. It is fundamentally designed, from the ground up, to authenticate and protect personal and sensitive information. Once systems are designed, built, and scaled, it is difficult to increase privacy and extremely challenging to simply add end-to-end encryption. At Skiff, we've spent years building modern privacy and cybersecurity as the cornerstone of products that look and feel like those we love to use today. For more details, check out our white paper 

Today, our product builds E2EE into document collaboration and group communication. Tomorrow, we see it as the foundation of an ecosystem of privacy-first software built to be usable, beautifully designed, and secure from the ground-up.

Demystifying end-to-end encryption

 that enabled users to sign up and login using just their MetaMask wallet - letting users access end-to-end encrypted documents and data on Skiff using an existing keypair (an Ethereum address).

Today, Skiff supports three products: Skiff Mail, Skiff Pages, and Skiff Drive and has grown to support numerous crypto wallets, including Brave Wallet, Phantom, and more.

Today, we’re excited to announce that Skiff is now a Login Partner of Unstoppable Domains where their over 2.5 million registered domains can now easily plug into Skiff to create an email address and identity. What does this mean? New users can sign up for Skiff and use any products in the Skiff ecosystem (Skiff Mail, Pages, or Drive) all using their Unstoppable Domain.

What is an Unstoppable Domain? It is the first functional NFT single sign-on service for Ethereum and Polygon and will replace the need for usernames and passwords across Web3. Just like connecting a wallet, users prove ownership over an Unstoppable Domain and are subsequently able to use that domain to log into Skiff, send mail, and collaborate with others.

We are excited for all owners of Unstoppable Domains to try out the new login functionality and can't wait to share all the new updates we have coming soon!

Skiff x Unstoppable Domains

 to introduce the next frontier in Web3 communication. Today, we are giving users with Keplr wallets the ability to not only directly sign up for Skiff’s suite of privacy-first decentralized products, but also to claim their very own @keplr.xyz domain address to use within Skiff Mail and with the world.

Skiff is dedicated to making privacy-first and decentralized products more accessible and user-friendly. This is why Skiff has built a comprehensive privacy-first, end-to-end encrypted, and Web3-native decentralized platform.

 empowers users to communicate privately and confidently by connecting and linking their crypto wallets to an encrypted, secure, and private email address, allowing for the most comprehensive and efficient wallet to wallet communication available.

 lets users write and store sensitive information that can be easily shared with collaborators, without ever breaking client-side encryption. Users also have the option to store their pages on the InterPlanetary File System for a completely decentralized experience.

 enables users to store all their files, regardless of file type, on a privacy first, end-to-end encrypted platform. These files can be easily accessed, downloaded and, retrieved. All your files are encrypted on your device, and, if you choose stored on a decentralized network (IPFS), files remain end-to-end encrypted and censorship resistant.

Keplr is the first open-source, IBC-enabled wallet that was built from the ground up to support interoperability and the Interchain ecosystem.

Explore the world of interoperable blockchain applications from one wallet, and manage assets, stake tokens and collect rewards, participate in governance, access NFTs, and more.

Combining powerful features into one user-friendly interface, Keplr simplifies connecting blockchain applications for developers and empowers users to interact with the emerging ecosystem of interoperable blockchains.

The next step is to verify that you actually own your Cosmos Hub address (we don’t want you to have any imposters!). Similar to 

, our server first generates a challenge token (called skiffLoginToken) for your wallet to sign.

Then, we use the Keplr API to sign the message using the 

 protocol. This signature is subsequently verified in order to claim the @keplr.xyz address, and if it passes we can safely assume that this is not an impersonation. We let you proceed to either creating a new account or logging into an existing one, depending on whether you’ve signed up.

 for you to use with your address and wallet. New custom domain, same end-to-end encryption. This new domain is only accessible to users who have signed an attestation to provide they have access to a particular Keplr wallet. This enables prviacy-first, trustworthy communication among users by significantly reducing the risk of impersonation or dishonest communications.

In building a platform for privacy-first, end-to-end encrypted, Web3 email, adding a distinct, verifiable address for every Keplr user builds credibility and trust for all communications in Web3.

Keplr Wallet: Web3 mail launch

Have you already upgraded to the Pro or Business plan and need some quick tips on setting up a custom email domain? You’ve come to the right place.

This blog covers how to connect your domain name to your account, add aliases for you and your colleagues, and create a business email or personal address with your own, custom domain name.

First, visit the Mail custom domains settings page: Click settings, then click “Custom domains.” On mobile, click the gear icon in the top right, and then “Setup domain” (yes, you can configure custom domains from mobile as well).

Then, click “add domain,” and type in your domain name. Click “next,” and wait for the loading spinner to finish loading.

Now, you’ll be on a screen with a list of DNS records for your domain, including an MX record, two TXT records, and two CNAME records. You’ll need to add all of these records to your domain from your hosting provider.

Once you’ve navigated to your hosting provider or domain registrar, add each record for your domain. Note that 

you must have the Skiff MX record at priority zero

, and the other records must be copied in perfectly for your domain to verify properly.

After copying in all of the records, that’s it! Wait approximately five to ten minutes for your records to publish, then for Skiff to verify them.

You’ve verified your custom domain. What’s next?

You can now add any number of aliases for that domain from the custom domains settings page. First, click “add alias” next to your domain. Then, in the popup, type in your desired alias, which can even be 

! From there, you’ll want to type in an alias, and then click “add.” You’ll see the alias show up below your custom domain.

From there, you can now send and receive mail using this alias on your custom domain!

Now, what if you want to add multiple users with aliases for your custom domain? This is a common case for business email addresses.

First, add people to your workspace from your Skiff Pages or Drive dashboard (

). Click settings, then your workspace name, and “add members.” Or, share your “Everyone” team. New users will need a new account to join your workspace.

From there, all users added to your workspace will be able to add aliases on any custom domains you’ve verified for that workspace. Once you’ve added users to your workspace, Skiff can become a great email provider for businesses, teams, families, and other organizations that seek to have email accounts for team members with a shared domain name. Startups can also leverage our 

 program, which provides up to $1,000 of credit for your organization to join on the Pro or Business plans.

. We’re also available at support@skiff.org.

Quick guide: Get your custom domain set up

Migrating to a new email account is no easy feat. Email is a main form of identity on the web, used for professional communications, keeping in touch with family, and critical accounts - including bank accounts and insurance reports. In this blog, we’ll cover the considerations, processes, and constraints you may have when migrating to a completely fresh email account. This includes email migration tools that automate the process of transferring data, tutorials for enabling email forwarding, and new email service providers that make it easy to switch.


 email today - and the average email user has almost two 

. As a result, millions of people consider switching, migrating, or simply opening new accounts every day. A decade ago, people typically sent mass emails to their contact list reminding contacts of their new mailing address; now, automated tools and checklists can make this process increasingly painless, regardless of your previous email provider.

Email forwarding is perhaps the oldest and simplest way to begin your migration process. We’ll briefly walk through the process to set up email forwarding for Gmail and Outlook, but most major providers will have tutorials in their documentation as well. Email forwarding will automatically send all incoming mail from your old account to a new email address of your specification.

After visiting gmail.com, in the top right, click 

A verification message will be sent to your new email address. Click the verification link in the message.

Go back to the Gmail settings page and refresh the page.

Enter your new email address in the "Forward my email to" field.

Email import provides greater simplicity, confidence, and peace of mind when switching accounts by transferring your entire old email inbox to your new email provider. Depending on your old and new account, you may be able to automate the transfer process, or you may have to export your inbox as files and import them again. However, there can be downsides to completely transferring an inbox from one provider to another. These include exhausting your storage space (depends on your provider’s storage space) and transferring any annoying spam, marketing, or promotional emails left in your old account (the worst outcome is to immediately transfer thousands of emails and regret your decision).

 inboxes, allow you to log in and import email with one click. This process takes only a single step to transfer your entire inbox; after signing in and granting permissions to the new service, it will automatically transfer them to your new provider.

: Otherwise, you may need to export your emails as MBOX or EML files. While Outlook exports emails as 

 that can be imported into another mail provider. Other email accounts, such as Hotmail or Yahoo, may provide export 

, which provides another automated method for transferring your inbox to a new provider.

Switching to a new domain name is perhaps the most straightforward part of the email migration process. First, you’ll need to ensure you have access to your domain’s DNS management records, likely through a DNS provider (Google Domains, GoDaddy cPanel, Namecheap, etc.). Then, you’ll need to replace existing DNS records - namely MX and TXT records - with DNS records for your new email provider. Email providers offer different tutorials for migrating MX records; for example, 

Before migration is complete, you’ll likely want to access your new account on a variety of platforms, including native desktop and mobile apps. Generally, all email providers offer native mobile applications, access via mobile webmail, and even purpose-built tablet apps. Depending on your communication needs, you may want to consider whether other access mechanisms are needed (such as 

 to your email account for automated email sending, filtering, or more).

Choosing an email provider can be a daunting task: What account will store future years of your life? We encourage considering a new email provider on these usability and quality factors:

: If you’re a frequent email user, you may check your email hundreds of times every day. Having a product that functions reliably, performs responsively, and works on all of your devices is a critical necessity. We highly recommend testing out your preferred provider’s iPhone, Android, and desktop apps, and, if needed, iPad or tablet applications as well.

: Email providers maintain vastly different privacy policies and terms of service. While some providers maintain the right to show you advertisements in your inbox, or based on the emails you view, others (such as 

) show no targeted advertising or can never read the content of your inbox. Legacy email providers - such as Hotmail and Yahoo - generally have the 

. At Skiff, we highly encourage focusing on privacy protections as one of the most important factors in choosing your next email provider, particularly when you may store medical information, family communications, and financial documentation inside your email account. After using an inbox for years, you will want to remain confident that you trust the company and organization behind it.

: Integrating email into other products and apps is also a critical need in signing up for a new account. For larger email providers - namely Microsoft and Google - email is integrated into a suite of products for collaboration and communication. Other providers also offer robust product suites, such as Skiff - with 

 - for file storage and real-time writing and collaboration. In many contexts, integrating email with real-time collaboration and file storage may be useful for sharing contacts, sending links, or uploading files.


At this point in your migration process, you’ll want to have a new email provider ready to go. Ideally, in following the migration checklist above, your new email address will have domain names set up, email apps downloaded onto your mobile devices, important old emails imported into a new inbox, and forwarding working seamlessly from your old account to new. Now, you simply have to make a final choice on email service provider.

Given the enormous number of global email users, the largest providers, including Gmail, Microsoft Outlook, and Yahoo, have become exceedingly popular. However, a new ecosystem of privacy-first email providers - such as 

 - are becoming popular for hundreds of millions of users.

Above, we advised making a decision based on usability, privacy, and integration with other products. But, this decision need not be final - and you can always try multiple providers for free and choose the one that best suits your needs.

Recommendations, tips, and tricks for a painless switch

Beyond the checklists above, we have a few tips that might make the transfer process easier:

: Once you’ve set up forwarding (see instructions above), we recommend testing with some sample emails to ensure that mail is properly delivered to your new address.

: Most major mail providers, including Gmail and Outlook, allow users to set up an auto-reply email that will automatically respond to incoming messages. So, when an important contact sends you a note, you’ll be able to automatically respond with a message about your email address.

Keep your old email address around, at least for some time

: You may want to search for old emails, contacts, attachments or more. Furthermore, if you chose not to transfer emails from your old account to your new account, you may need access to this data.

: If you purchase and set up a custom email domain (as in, not the default @outlook.com or @gmail.com addresses), switching email providers becomes significantly simpler. Instead of migrating to a completely new address, you’ll be able to keep your old address but migrate to a new provider, new mobile apps, and more.


Finally, native mail products can make the process of transitioning to a new email address simpler. The mail applications built into many desktop clients, such as Thunderbird, Apple Mail, or the mail applications on iOS and Android, enable users to log into multiple email accounts on the same device. For a time, you may consider logging into both your old and new email addresses on the same device and switching between them. Eventually, once you’ve imported mail, set up apps properly, and informed your contacts, you’ll be ready to fully make the switch.


In this blog, we covered many critical steps to consider when transitioning to a new email address. Although moving so much important information - messages, attachments, contacts, and more - to a new platform can be intimidating, incremental steps such as forwarding, email import, and using your own domain can make this process easier. With constant innovation in email privacy, providers, and apps, we recommend continuing to try new email services until you find one that best suits your communication needs.

How to migrate to a new email account

Working together on Skiff yields critical privacy benefits

 for your communications, files, documennts, and more. Inviting your team brings numerous new features - as well as an opportunity to leave Google Workspace, Microsoft Office, and other less private ways to collaborate.

We’ve built Skiff to be a privacy-first, end-to-end encrypted workspace for individuals, teams, and businesses - and sharing other members on your team is a critical need to jumpstart your privacy.

This blog walks through how to set up your workspace for team collaboration, how to invite your colleagues to collaborate, and how to add a shared custom domain. At any point, if you have questions, need help, or want an onboarding specialist to help with the process, we are available at hello@skiff.org for questions.

. This will prompt you to create an individual account, which will be the first member and administrator for your workspace. From there, you can customize your organization’s name from the organization 

On this settings page, you can change your organization’s name, add teams, delete teams, or add and remove members. Teams are organizational units of your workspace, such as Engineering, Design, and HR teams. We’ll cover sharing your organization with colleagues in the next section.

To use a shared custom domain and share teams (“Design,” “Business,” etc.), you need to add members to your workspace. This can be done from the organization settings page as well (

https://app.skiff.com/dashboard?settingTab=organization

Workspace members will automatically be shared on all public teams within your organization, including the “Everyone” team. Invite-only teams will not be automatically shared, unless you add new members to them.

As noted above, you cannot add existing Skiff accounts to your workspace. Instead, you can send an email invite link that must be used to create a new account and join a workspace.

Adding a custom domain is critical for any organization that wants shared, personalized emails at the same domain for a business, family, or other group. To set up a custom domain, visit the custom domain settings page: 

https://app.skiff.com/mail?settingTab=custom+domains.

 Note that you will need to be on the Pro or Business tiers to do so.

Once you enter in your domain name, you will see DNS entries (MX record, TXT records, and CNAME records) to add via your domain registrar. Once added, these may take some time to populate. All records are necessary to enable mail sending and receiving at your domain, as well as critical security checks for email protection (SPF, DKIM, and DMARC protection).

Once the domain is added and verified, anyone from your workspace will be able to add aliases using that custom domain. You can refer to our longer tutorial 

 on how to add and verify a custom domain.

Can existing Skiff accounts be added to new workspaces?

No - you must create new accounts to join a Skiff Workspace. Each account has a distinct mail inbox, drive, pages, and more.

How can I sign into multiple Skiff accounts?

On the web, click the workspace selector in the top left corner, and then click “Add account.” You will be able to sign into multiple Skiff accounts at once that each belong to a different workspace. You can also sign into multiple accounts on the mobile Pages and Drive apps, with multiple accounts on Mail coming soon.

Yes! Any admin can remove workspace members from the organization 

. Once removed, these workspace member accounts cannot be recovered.

Can a custom domain be shared across users?

Yes! Every member of your workspace can have a distinct custom domain alias, like a@yourcompany.com and b@yourcompany.com. That way, you can even add more aliases, like sales@, ops@, or hello@yourcompany.com.

Yes! You can add up to two custom domains on the Pro tier, and you can add up to five custom domains on the business tier. So, if you need to manage multiple domain email addresses, or multiple businesses from one workspace, you can easily add these domains to your Skiff account.

How to invite your team to a shared workspace

 and onboarded your team to your new, privacy-first workspace. How can you set up a shared custom domain for you and your colleagues to communicate internally and externally?

How to create a workspace and invite your team

To create your workspace and share the rest of your team, we recommend referencing our blog on “How to invite your team to Skiff.” That blog covers the signup process and how to use the organization settings page (

) to send invite links that can be used to join your team. Find the full blog 

For a quick overview tutorial: First, sign up at Skiff’s signup page (

); then, visit the settings page and click your workspace name. There, customize your workspace name and icon, and then invite other team members to join.

To share a custom domain, you must invite your team to the workspace, not just to a single Skiff Page or folder

. Every workspace member will be able to use shared custom domains.

As a first step, you will need to upgrade your account to be on Skiff’s 

, which enable adding up to two (Pro tier) or five (Business tier) custom domains.

Then, you need to visit the mail custom domains 

, or click settings and then “Custom domains” from inside your inbox. After entering in your domain name, Skiff will provide DNS records (TXT records, CNAME records, and an MX record) for you to add to your domain registrar.

Once your records are added and published, Skiff will indicate that your domain is “verified,” which is necessary before you can add aliases to this domain. Note that all of these records must be published to ensure mail is sent and received safely and reliably.

We’ve also written a much longer, step-by-step blog on how to set up a custom domain - find it 

Once you have shared your workspace and have a verified custom domain, you can add aliases using this domain from the Mail custom domains settings page.

Unlike @skiff.com aliases, which must be four characters or longer (on Pro or Business tiers) and cannot contain certain characters, custom domain aliases have far fewer restrictions and can even be one letter!

Your colleagues in your workspace will also be able to add custom domain aliases, so you can add a@co.com, b@co.com, and even sales@, marketing@, business@, and more.

If you have questions or need support at any time, please reach out to us at support@skiff.org. In particular, we can help check on your custom domain verification, workspace paid plan status, and assist with any problems that may arise with aliases or DNS providers.

. Thank you for using Skiff, and we hope to deliver privacy-first, intuitive products to you and your team.

Yes - your workspace can have up to two domains if you are on the Pro plan, or five domains if you are on the Business plan. Once multiple domains are added, you will be able to both send and receive mail at any verified domains.

Is there a limit to the number of aliases per domain?

There is no limit to the number of aliases you can add per custom domain.

What characters can be added to a custom domain alias?

 aliases, you have much more flexibility on adding custom domain aliases, and you can even add one character (a@domain.com) aliases for you and your other team members.

Emailing support@skiff.org is the best way to get quick help on adding your MX, CNAME, and TXT records properly.
