Other good mail apps.
An honest comparison.

We compare SevenMail with Mimestream, Superhuman and Spark, and with Apple Mail, which comes with your Mac: what they cost, where they run, where your mail goes, and what each does well. Every fact has its source and the date we read it. Where another app is the better choice, we say so.

Four routes for one message

A new mail leaves Google and ends up on your Mac. What happens on the way differs.

Each line is the route as the vendor’s own pages and policy describe it. Where a page does not say, the box says so. This is a description, not a security rating.

How we compare

Sources

We read the vendors’ own pages and policies and note the day. Where a page loads by script or is closed to us, we say so and use a secondary source only as a pointer.

The same rows

Both apps get the same rows. A row we cannot back with a page is left out, not guessed.

Not listed

“Not listed” means the page does not mention it. It does not mean the app cannot do it.

Corrections

If something is wrong, write to support@sevenmail.app. We check it within a week and note the change.

Our own cells

SevenMail’s column says what is in the beta and what is planned. Nothing is marked as released before it is.

Not yet tested by hand: we read what the vendors publish. We have not installed the other apps for this page.

Mimestream, Superhuman, Spark, Readdle, Apple Mail and Apple Intelligence and their icons belong to their owners. SevenMail is not affiliated with them; their icons are shown only to say which app is meant. The facts on this page come from their own pages and policies, as read on the day shown; prices and features change.
