Built for people with too many inboxes.
Every feature below ships today in public beta. Nothing behind a "coming soon" badge on this page.
Gmail, Outlook, Yahoo, IMAP - one view
OAuth for Gmail, IMAP + app password for Outlook, Yahoo, iCloud, Fastmail, and any other IMAP/SMTP provider. We open an IMAP IDLE connection so the unified inbox stays fresh without you tapping refresh.
- ✓ Gmail / Google Workspace via OAuth (web)
- ✓ Outlook / Microsoft 365, Yahoo, iCloud, Fastmail, and any other IMAP/SMTP provider via app password
- ✓ Per-account or unified view, switchable from the sidebar
- ✓ Read state, archive, and delete sync back to the source mailbox
One workspace, every mailbox
Your plan covers a pool of account slots. Fill them with personal mailboxes, custom domains, or any mix - aliases on an existing mailbox don't burn a slot.
Send + receive on your domain
We provision an AWS SES identity for you, hand back DKIM + MX records, and flip the switch as soon as DNS propagates. Inbound and outbound, on the same custom address, in the same app.
Bring the domains you actually use
Stop paying Google $7/user/month for every casual side project domain. SuperMail routes inbound mail through SES and stores bodies in S3 under your workspace - no new addresses to memorize, no forwarding hacks.
- ✓ Guided DNS setup (MX, DKIM, SPF, DMARC)
- ✓ Multiple From addresses per domain
- ✓ Receive at catch-all or per-alias
- ✓ Custom domains share your account slots - no separate domain quota
Compose without dread
Rich-text Lexical editor with bold, italic, lists, and links; drag-and-drop attachments; and a multi-From picker that remembers which identity you used last on each thread.
Write replies that don't get buried
Drafts save when you click Save or close the composer, then sync across devices. Attachments land in S3 and stream straight through SES, so a 20 MB investor deck doesn't clog the outbox.
Web, iOS, and Android - same workspace
The mobile apps are true natives, not wrappers. Push notifications per account, biometric unlock, and a shared design system so nothing looks out of place.
Download the apps →One subscription, every device
Your plan covers web, iOS, and Android without extra seats. Install on as many devices as you want - the same mailboxes show up on each.
