Stop polling and start reacting. Mailwon Webhooks notify your backend the millisecond an event occurs—from delivery to engagement.
Sync 'bounce' and 'complaint' events to your database instantly to stop sending to bad addresses.
Trigger welcome flows or notifications when a user opens an email or clicks a specific link.
Every payload is signed with a secret key so you can verify the authenticity of every request.

}We ensure your events never get lost in transmission.
If your endpoint is down, we use exponential backoff to retry delivery for up to 24 hours. Your data is always safe.
Generate unique signing secrets for every endpoint. Verify the HMAC signature to ensure data hasn't been tampered with.
Our webhooks are dispatched from a set of static IP addresses, making it easy to whitelist them in your firewall.
