Auth0
Use Deckle as the SMTP provider for Auth0 tenant emails.
Configure Auth0's custom email provider to send through Deckle's SMTP relay for verification, password-reset, and MFA emails.
Set it up#
- Generate a Deckle SMTP key below and copy it.
- In Auth0 → Branding → Email Provider, select SMTP.
- Enter the host, port, username, and the key as the password.
- Verify your sender domain under Domains so mail passes SPF and DKIM.
