Writing about Loupe?

In one sentence

Loupe is a free, open-source mail app for Android that is as simple as the best phone mail apps on the surface, with desktop-class search, rules and encryption underneath.

In a paragraph

Loupe is an independent mail app for Android, with iOS planned. It rebuilds HTML newsletters to fit the phone (Readable mode), searches with a full expression language across the phone and the server, keeps Smart Mailboxes and rules on the user's own mail server, and supports OpenPGP and S/MIME. It works with any IMAP or JMAP provider. Loupe has no servers of its own and collects no data: no analytics, no telemetry, no ads. It is open source under the MPL-2.0 and built in public on GitHub.

Facts

Please

• Write "Loupe", not "LOUPE" or "Loupe Mail".
• Don't describe Loupe as made by or affiliated with Mozilla or Thunderbird. It's independent; it works with Thunderbird's tags and settings export.
• Don't change the logo's colours or proportions.
