Recommended Email Clients

The app you read your mail in is as important as who hosts it. A good client can block tracking pixels, strip dangerous HTML, and layer end-to-end encryption on top of any mailbox, while a careless one leaks your IP address and reading habits to every sender. The trade-off is usually convenience: the most private clients ask for more setup and encryption only works when the person you write to supports it too.

How to choose an email client

An email client is separate from your email provider and switching clients is painless so pick one that adds privacy rather than stripping it away. Prioritise open-source apps that block trackers by default and support OpenPGP or S/MIME, then weigh how much setup you are willing to do against how polished you want the experience to feel. On mobile, a client that avoids Google's push infrastructure keeps more of your metadata out of third-party hands. Remember that even the best client cannot make a snooping provider private so pair a strong client with a trustworthy mailbox.

Here are some things to look for.

  • Open source. Public code can be audited so privacy claims can be checked rather than simply trusted.
  • OpenPGP or S/MIME support. Built-in encryption lets you protect message contents end to end, not just in transit.
  • Tracker and pixel blocking. Stops senders from learning when, where, and how often you open their mail.
  • Works with any provider. Standard IMAP and SMTP support means you are never locked to one mailbox or vendor.
  • No forced Google services. Clients that skip Firebase push keep your message metadata away from extra third parties.
  • Maintenance and jurisdiction. Active updates and a privacy-friendly home country lower your long-term risk.
