Gmail is a free, advertising-supported email service released on April 1, 2004. Over 1.8 billion users worldwide make it indisputably the most popular email platform. In comparison, just 400 million use Microsoft Outlook and 225 million have signed up to Yahoo Mail. In a world of data-driven digital marketing, can you really trust an email…
Or maybe that is backwards, you could also say that, because of the sheer number of users, and the amount of people believing it is a de-facto standard,Google (or other companies that have similar issues) really don’t have to worry about compatibility issues, because many people will actually change the other software and services they use to fit around them.
Tutanota: (Free and Open Source Email Provider)
Skiff Mail (skiff.com) is open-source, end-to-end encrypted, and we just launched adding a custom domain on the free tier. That means you can use it as a business email with your own domain. I think Skiff is the only product on the list that has that capability!
Tatem is a new email client that will pair with Outlook (as well as Gmail), and does claim to offer high privacy / security.
Mox
self-hosted email server requires an attention. GitHub - mjl-/mox: modern full-featured open source secure mail server for low-maintenance self-hosted email
From their documentation:
Mox aims to make “running a mail server” easy and nearly effortless. Excellent quality (open source) mail server software exists, but getting a working setup typically requires you configure half a dozen services (SMTP, IMAP, SPF/DKIM/DMARC, spam filtering), which are often written in C (where small bugs often have large consequences). That seems to lead to people no longer running their own mail servers, instead switching to one of the few centralized email providers. Email with SMTP is a long-time decentralized messaging protocol. To keep it decentralized, people need to run their own mail server. Mox aims to make that easy.
