Send profiles
A send profile is one “From” identity on a given account. Most accounts have a single send profile (your primary address), but Gmail aliases, Outlook Send-As addresses, and custom domains can all be attached as additional profiles on the same underlying mailbox.
What lives in a profile
- From address (e.g.
blake@example.com) - Display name (e.g.
Blake Stacks) - Reply-To (optional - defaults to the From address)
- Signature (plain text or rich text; per-profile so you can keep a casual sig on personal mail and a formal one on work)
- Default flag - which profile is pre-selected in the compose From picker
Adding a profile
Settings → Accounts → [account] → Send profiles → New.
- For Gmail (OAuth), the From address must be registered as a Gmail “Send mail as” alias. Add it at mail.google.com/mail/u/0/#settings/accounts and verify it, then refresh send profiles in SuperMail.
- For IMAP/SMTP accounts (Outlook, Yahoo, iCloud, Fastmail, etc.), any From address can be used as long as your SMTP server accepts it. Most providers require the From to match the authenticated username; Microsoft 365 also requires the address be added as a “Send As” alias on the mailbox before SMTP will accept it.
Custom-domain profiles
When you add a custom domain, every From address on that domain is available on
any account that manages the domain. You can compose from hello@yourdomain.com using the
custom-domain send path even if your primary account is Gmail.
Picking the right profile
The compose window’s From picker shows every profile across every account. Click it and pick the identity you want to send as.
SuperMail remembers the From profile you used last in a given thread and defaults to it on reply.
