  • Per-account callback URL

What is EmailBridge

EmailBridge fills a feature gap in MessageMedia’s API by enabling email delivery of SMS replies with granular control over recipients. Unlike MessageMedia Hub Automations (which only provides blanket SMS to email delivery), this service lets you route replies to specific email addresses for each destination. Our webhook service intercepts reply callbacks and delivers them to the precise email address you specify per contact, with robust whitelist security to prevent misuse.

The Challenge We Solve

The Problem

MessageMedia’s API lacks granular email reply controls. Hub Automations only provides blanket SMS → email delivery without per-destination customization.

Hub Automations = blanket delivery only

No per-contact email routing

Cannot customize recipients per message

Replies go to one place for all contacts

No whitelist security controls

Our Solution

Intercept MessageMedia reply callbacks and route to specific email addresses per destination, with whitelist security and multi-account support.

Per-destination email routing

Email whitelist prevents misuse

Multi-account MessageMedia support

Simple API integration

Just add callback URL + metadata
