Know when your email stops arriving

Transactional email fails silently. Password resets stop arriving, receipts bounce, and the first signal is usually a support ticket from someone who could not sign in.

Delivery webhooks make that failure loud. A spike in bounces or a spam complaint is the sort of thing worth knowing on the day it starts, not at the end of the month when someone opens the analytics tab.

The events worth turning on

Hard bounce

An address that will never work again. Worth catching before the retries pile up.

Spam complaint

The event with the longest tail: complaints damage deliverability for every future send.

Delivery delayed

Usually the first visible symptom of a provider or reputation problem.

Integrations for this

Each of these sends the events above. Setup is the same for all of them.

Common questions

Will I get a notification for every bounce?
Only if you subscribe to them. On a large list, most people take spam complaints and delivery failures and leave individual bounces alone.
