How does Emailit retry failed webhooks?
Failed requests are retried with exponential backoff: after 5 minutes, 30 minutes, 2 hours, 5 hours and then every 12 hours, for 11 attempts over about three days. You can also retry manually from the request log.
How do I verify a webhook signature?
Compute an HMAC-SHA256 of the timestamp and raw body with your webhook secret and compare it with the X-Emailit-Signature header. The docs include examples in several languages.
How many webhook endpoints can I create?
Pay as you go includes 3 endpoints, Pro 10 and Business 100. Contract plans are flexible.
Your next email could already be delivered.
Create an account, verify a domain and send in under five minutes.
