Find your email provider’s IMAP and SMTP settings
Choose the right tutorial for Gmail, Outlook.com, Office 365, Yahoo Mail, GoDaddy Email, or Proton Mail.
Choose who hosts your mailbox
Use the service you sign in to for webmail, not just the company that registered your domain. IMAP receives mail; SMTP sends it. AeroMailer also supports POP3 receiving where your provider offers it.
- Gmail and Google Workspace — use a Google App Password only where permitted.
- Outlook.com, Hotmail, and Live — Microsoft requires OAuth2; the preset is a server reference.
- Microsoft 365 / Office 365 — work or school Exchange Online, subject to tenant policy.
- Yahoo Mail — use a Yahoo-generated app password.
- GoDaddy Email — distinguish Professional Email from Microsoft 365.
- Proton Mail — paid Mail Bridge runs locally; eligible accounts can also use a separate send-only token.
Before testing
Go to Workspace → Accounts → Add Account. A preset only fills editable host, port, and encryption fields; it does not create a mailbox, grant access, or provide OAuth2. Confirm the required sign-in method first. Test Connection checks the selected connection without sending mail. For a real end-to-end check, send a message to an address you control and reply from that address. Never share a password, token, or private key in screenshots or support tickets.
