Connect your existing email to ChatGPT
Use an AI assistant with your business mailbox without changing your address or moving your email.
MailBridge AI
Authorized connections
Standards-based mailbox access and compatible AI clients.
IMAP mailboxes
Custom-domain and hosting mailboxes with publicly reachable IMAP over valid TLS. Guided hosting presets and advanced IMAP settings are available. Provider restrictions and app-password requirements still apply.
ChatGPT and MCP
MailBridge exposes account-scoped MCP tools through OAuth for recent messages, optional historical context, authorized send/reply, scheduling and execution receipts. Availability in each host and account must be verified; an installed card alone does not prove an authorized connection.
Outbound transport
Encrypted per-mailbox SMTP configuration or the implemented HTTPS sending-provider route. Your sending identity must be authorized. Hosted SMTP network restrictions may require an alternative compatible route.
Billing
Stripe handles supported subscription checkout and customer-portal flows in the configured environment. The current release remains TEST; public paid checkout is closed.
