Communications & Email Templates
5 min read·Updated Apr 29, 2026
The Communications tab is where Authaz's emails get configured. It has two sections:
- Email Provider — connect your sending account (Resend). Authaz uses your account, your domain, your reputation.
- Email Templates — customize the 12 transactional emails Authaz sends (welcome, magic link, password reset, invitations, account recovery, MFA reset).

Email provider#
The dashboard supports Resend as the bring-your-own provider.
Why bring your own provider#
- Deliverability. Emails sent from your domain via your warmed-up sender land in inboxes; emails sent from a generic Authaz sender are more likely to hit spam.
- Branding. The "From" address is , not something Authaz-flavored.
