Using Loupe
- Reading mailRead any message comfortably in Loupe: Readable, Original and Plain views, text size, dark mode colours, images, links, attachments and message details.

- Smart MailboxesSave any search as a Smart Mailbox in Loupe. It is stored on your own mail server, so it appears on your other devices with no account or cloud service.
- Organising mailSwipes and Undo, the Filter button, flags, VIPs, Thunderbird-compatible tags, folders, archiving, junk, and snooze that works across mail apps.
- Writing and sendingCompose, reply and forward in Loupe, attach files, choose who you send as, undo a send, schedule mail for later and handle the Outbox.
- SubscriptionsSee which newsletters you never read, unsubscribe in one tap, block senders, and keep the mailing lists you write to in one place, all on your phone.
- RulesSort new mail automatically in Loupe with rules that run on your phone or on your mail server as Sieve, written as searches, with a live preview.
- NotificationsHow Loupe checks for new mail in the background on Android, what notifications show, their actions, the app icon badge, and experimental Instant Delivery.

- Mailing lists and patchesRead mailing lists as forum-style threads in Loupe, mute threads, reply to the list, use plain text for technical lists, and read patches as diffs.
