Setting up a private email server—pros, cons, and alternatives
Is setting up a private email server a good idea? Find out the specifics in our in-depth guide, and learn about alternatives to a private email setup.Despite being the oldest form of online communication, email is still the go-to option for any serious digital correspondence—especially in business. While most people automatically defer to email services from the biggest mainstream providers like Microsoft and Google, that’s not the best idea if you take email privacy seriously.Many large email service providers (ESPs) access the contents of your emails and use the information they find to create targeted advertising campaigns—and that’s not the only way your privacy may be compromised with a typical email setup. One of the methods of addressing such privacy and security concerns is a private email setup.In this article, you’ll learn about setting up a private email server as a way of taking your email privacy protection to the next level. We’ll discuss:
Private email servers are difficult to set up and run, rented servers are unreliable, and large ESPs come with privacy issues. Luckily, there’s a fourth option—email clients with end-to-end encryption (E2EE), like Skiff Mail.

What is a private email server?
Email servers are specialized computers whose primary purpose is to facilitate your email correspondence. They receive and send emails and store them before they’re transferred to another server or downloaded to your device.A private email server is one that you set up and own—a computer that handles your incoming and outgoing email messages. You control who has access to it and manage its storage, which ensures a higher degree of privacy than what you’d get with any major ESP.Here’s the basic process of sending an email with Gmail, Outlook, or any other email client:- Email is uploaded to your ESP’s server
- Server looks at the address of the recipient’s email server
- Message is sent to the recipient’s server
- Recipient’s email client downloads the message from their email server
How to set up a private email server
The first step in setting up a private email server is investing in the required hardware and software. Besides this initial investment, running an email server comes with ongoing monthly costs. The exact expenses can vary depending on your location and particular hardware setup.If you want to set up the hardware yourself, you’ll need a computer with sufficient storage space for your server software and messages. Otherwise, you can look for a cloud hosting solution and rent hardware from a hosting provider.Regardless of the option you choose, the email server will also need a custom email domain name—the part that comes after @ in your email address, like outlook.com or gmail.com. You can buy these domain names online.The next thing you need is a high-speed, stable internet connection to ensure maximum uptime on your private email server. Finally, you’ll also require server software, including:- An operating system (OS) like Windows or Linux
- Software for routing and sorting email
- A spam filter
- Virus protection
Advantages of a private email server
The main advantage of setting up a private email server instead of relying on an ESP server is more privacy. A private email server increases your online security by:- Ensuring no ESP employees can ever access your emails
- Preventing any automatic scanning of your emails for targeted ads, training of machine learning algorithms, or similar activities
- Eliminating the possibility of a law enforcement or government agency requesting email data from your provider
Disadvantages of a private email server
There are a lot more drawbacks to setting up a private email server than there are benefits. The most notable are:- Time and effort required—Setting up a private server is difficult and requires advanced technical knowledge. Many people also don’t have the time to manage an email server actively because it demands constant patches and updates. If you don’t know the intricacies of web technologies and aren’t tech-savvy, you’ll need time to learn the particulars first
- Various software and hardware equipment necessary—You must invest in a complex hardware setup, a variety of software, or a cloud hosting solution
- An ongoing responsibility—Running a server comes with constant maintenance work and security updates. Managing a private email server is a massive responsibility in the long run because higher privacy and security aren’t a given. You’re accountable for every aspect, so your emails are as secure as you make them
- Low reliability—Unlike Google or Microsoft, you don’t have a globe-spanning server infrastructure worth millions of dollars, and your private email setup will be less reliable. A mainstream ESP guarantees decent accessibility at all times—if a Gmail server fails, Google always has alternate routes and backup solutions that ensure constant uptime. If your private server fails, you can’t send an email until you fix the problem

Why hosting providers aren’t an ideal solution
Finding a hosting partner and renting a server solves issues such as worrying about server hardware. Unfortunately, the approach entails other problems:- Dealing with an intermediary
- Hosting providers aren’t always reliable
- Migrating difficulties
Type of email server | Pros | Cons |
Major ESP server | Reliable uptime, a guaranteed level of security, no technical knowledge required, and zero management or maintenance required from users | Lower level of privacy and lack of actual ownership of your email data |
Private email server | Highest degree of control and complete data ownership | Highest level of responsibility, substantial technical knowledge required, constant maintenance and management required, and substantial hardware and software requirements |
Rented server from hosting provider | More control than with an ESP and zero hardware requirements | A high level of maintenance required, less stable and reliable than major ESPs, dealing with a 3rd party, and migration to another provider is often difficult |
Solve your email security issues quickly with Skiff
Every server solution we’ve mentioned above comes with specific issues. Skiff successfully avoids them all by providing:- Zero privacy concerns
- No maintenance responsibilities
- A modern, easy-to-use productivity suite
- Total data ownership
Zero privacy concerns
Skiff’s end-to-end encryption email is the ideal way to ensure your online privacy. The platform uses an encryption algorithm that involves two corresponding keys—one for encrypting and the other for decrypting messages. The encryption is performed at the device level, ensuring your communication remains private and unreadable to anyone but the intended recipient.Most ESPs provide some form of encryption, but their solutions only protect email data while in transit or when resting on a server. E2EE does both by encrypting emails on your device before they’re ever uploaded to a server. As a result, no one has access to your emails and attachments, including perpetrators of email attacks and the email service provider itself.No maintenance responsibilities
