Hosted mailboxes

Hosted mailboxes receive mail into your plan’s inbox storage allowance. Create an inbox for yourself or each member of your team. Use your own domain so outgoing messages carry your name and customers know where to reply.
Replace YOUR_20_CHARACTER_ID with the domain ID returned for your account. The new address combines localPart with that domain. List with GET /mailboxes, read with GET /mailboxes/{id}, delete with DELETE /mailboxes/{id}. Watch usage with GET /mailboxes/storage.

Mailbox credentials

Issue SMTP/IMAP credentials for a mailbox client:
Credentials are returned once. Rotate them anytime with POST /mailboxes/{id}/credentials/rotate.

SMTP relays

If you send through an external SMTP relay, register it with POST /smtp-relays. Supply name, smtp_host, smtp_port, smtp_username, smtp_password and smtp_security (starttls, ssl_tls or none). Update with PATCH /smtp-relays/{id}.

Connect your mail app

Use the IMAP and SMTP hosts, ports and TLS settings shown in your mailbox dashboard. Use the generated mailbox username and password, rather than your API key, in your mail app. IMAP receives and synchronises mail; SMTP sends it. Send a message to the mailbox and reply from it to check both directions.
