Email Bridge
Send iMessages to any phone number by composing an email. Works from Gmail, Outlook, or any email client.
How It Works
- Compose an email in your email client
- Set To 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
Basic (uses first available line)
To: +19042956129@send.tuco.ai
Subject: (anything — ignored)
Body: Hey, wanted to follow up on our conversation yesterday.
Specific line
To: +19042956129-line_abc123@send.tuco.ai
Requirements
- Your email address (From) must be registered in Tuco
- Your workspace must have at least one active iMessage line
- Phone number must be in E.164 format (
+ country code + number)
Error Handling
If something goes wrong, you receive a bounce email:
| Error | Cause |
|---|
| Invalid phone number | Check format: +19042956129 |
| Not authorized | Your email isn’t registered in Tuco |
| No active lines | Set up a line at Lines → Purchase |
| Send failed | Recipient may not have iMessage |
Security
The Email Bridge verifies your identity by looking up your sender email in Tuco’s user database. SPF/DKIM from your email provider is a secondary check — not the primary auth mechanism.
