SuperMail documentation

SuperMail is a multi-provider email client. It unifies Gmail, Outlook, Yahoo, and IMAP/SMTP accounts alongside your own custom domains - on the web, iOS, and Android.

These docs cover the product in nine sections:

• Getting started - the 15-minute onboarding path.
• Email accounts - connect providers, manage re-auth, handle failures.
• Custom domains - add a domain, configure DNS, start sending.
• Inbox - reading, threading, tags, search, contacts.
• Compose - writing, attachments, replies, drafts.
• Mobile apps - install, push, biometrics.
• Billing - plans, usage, cancellation, data export.
• Security & privacy - how data is stored and protected.
• Reference - API, search syntax, troubleshooting.
