EmailWebhook

Turn Gmail and Outlook into a real-time webhook API

Clean JSON webhooks

Get granular, standardized events such as inbox.added, inbox.read, sent.added, drafts.added, spam.added, label.added and catch-all deletion events for both Gmail and Outlook.

Zero duplicate events

Advanced deduplication stops the same Gmail message from firing more than once, so downstream systems never process duplicates.

Reliable delivery and replays

Failed deliveries are retried with exponential backoff for roughly 1.5 hours, and all events are stored for 30 days so you can replay any delivery via the API.

One API for Gmail and Outlook

A single REST API sends emails, lists messages, manages labels and migrates users across Gmail and Outlook with encrypted credential storage.
