Know the moment it lands
Delivery, bounce, complaint, open, and click events reach your endpoint within seconds of happening. Signed, retried, and replayable.
The whole lifecycle
Six event types cover the sending lifecycle (sent, delivered, bounced, complained, opened, and clicked), and receiving adds email.inbound and mailbox.message.received. Every payload is signed with HMAC-SHA256 in the X-EuroMail-Signature header, and payloads are additive. New fields appear, existing ones don’t break.
{
"event": "delivered",
"to": "[email protected]",
"smtp_response": "250 2.0.0 Ok"
}Retried, then replayable
A non-2xx response or timeout triggers retries at 1 minute, 5 minutes, 30 minutes, 2 hours, and 24 hours. After five failures the event is marked undeliverable, and stays replayable from the dashboard event log, so an endpoint outage on your side never loses data. A built-in test tool fires sample events at any URL.
