Envello
Email API for authentication emails

Magic links, OTP codes and password resets that arrive while the user is still waiting

Auth email is the one category a user actively waits for. Envello sends it through AWS SES in Frankfurt, keeps the full delivery log searchable, and stores the recipient data in the EU.

Retry without double-sending

Pass an Idempotency-Key header and a retried request after a timeout returns the original result instead of sending a second code.

Every send, delivery, bounce and complaint is in the log: 7 days on Free, 90 days on Pro, up to 365 on Scale. Support can answer "I never got the email" in seconds.

Suppression handled for you

Hard bounces and complaints are suppressed automatically, so a typo'd signup address doesn't keep hurting your sender reputation.
