Key considerations for selecting an email client for Mac

No email client is universally better than others—the best option for you will depend on:
  1. Features it offers
  2. Design of the user interface
  3. Level of security and privacy the email client offers

Clearly define your feature requirements

When selecting an email client, consider the essential features you rely on in your daily workflow. For example, if you frequently communicate across different time zones, having email scheduling and snoozing capabilities is advantageous. In case you manage multiple email accounts simultaneously, robust organization and labeling features are crucial.Since your email client is supposed to optimize your productivity and streamline your efficiency, you should also explore solutions with advanced add-on support and third-party integrations.

Choose an easy-to-navigate user interface

An email client’s user interface should be intuitively designed to provide a user-friendly experience and ensure accessibility for users of varying skill levels. A well-designed, minimalistic interface can reduce the strain on your eyes, which is especially significant if you spend considerable time emailing. An intuitive and straightforward design enables users to swiftly locate the desired features and organize emails effortlessly.

Prioritize security and privacy in your email client

The security aspect rests with your email service provider (ESP). It should implement advanced safety standards to shield your online conversations from unauthorized access.Most email services encrypt your emails to protect them during transmission or while resting on servers. The trouble is that they typically use weak encryption protocols leaving your data vulnerable to attacks at certain points.Most mainstream providers also retain control of the decryption keys, which means they can access your messages at any time. For example, Gmail implements the Transport Layer Security (TLS) encryption protocol that protects your data during transit between the sender and the recipient but leaves it vulnerable when resting on the providers’ servers. They encrypt the messages on their servers and keep a copy of the keys, endangering your:
  • Security—a potential hacker that infiltrates the servers can steal the decryption keys and access your messages
  • Privacy—providers can see the plaintext copies of your emails, scan them for relevant keywords, and sell them to advertisers
For maximum security, your provider and email client should offer end-to-end encryption (E2EE). It keeps your correspondence secure by encrypting your messages on a device level so that nobody but the recipient—the only person with the decryption key—can access them. Your emails are safe from third parties, hackers, and everyone but the person you intended them for—including the provider.
