ROUTING / FORWARDING

Forward to Gmail or Outlook

Receive company mail in an inbox you already use and reply through a protected relay.

Enable forwarding

Open the mailbox in Settings → Inboxes, add the Gmail, Outlook, or other destination, and request verification. Startup Mail sends a six-digit code to that address. Enter the code to prove you control the destination.

Forwarding starts only after verification succeeds.

The delivery route

EXAMPLE
customer@example.com
        ↓
hello@yourcompany.com  (stored in Startup Mail)
        ↓
your-current-inbox@gmail.com  (forwarded copy)

The original remains available in Startup Mail. Forwarding adds another copy; it does not move or delete the source message.

Reply from the forwarded copy

Forwarded messages use a signed, expiring Reply-To relay. When you choose Reply in Gmail or Outlook, that route maps the response back to the original Startup Mail mailbox and conversation.

What does not synchronize

Forwarding is not IMAP or Exchange sync. Read state, stars, labels, folders, archives, sent folders, and deletions do not synchronize between Startup Mail and the destination inbox.

Automatic disablement

Startup Mail turns forwarding off after a hard bounce to the destination. Fix or replace the address, then verify it again. You can also disable forwarding manually from the mailbox settings at any time.
