How Email Bridge Works
Send iMessages by emailing+phone@send.tuco.ai from your email client. No app, no API, no setup beyond having a Tuco account.
Sending a Message
- Compose an email in Gmail, Outlook, or any email client
- Set the To field to:
+19042956129@send.tuco.ai - Write your message in the email body
- Hit Send — Tuco sends it as an iMessage and emails you a confirmation
Email Formats

+19042956129@send.tuco.ai | Uses your first available active line |
+19042956129-1@send.tuco.ai | Uses a specific line number (shown on Lines page) |
