Custom Email

Send transactional emails from your own domain with full SMTP configuration, custom templates, and real-time delivery tracking

Custom Email

Your Emails, Your Brand

By default, AuthAction sends password resets, email verifications, and other transactional emails from a shared address. With Custom Email, you bring your own SMTP provider and sender domain so every email arrives from noreply@acme.com — not from AuthAction.

Connect any SMTP provider — AWS SES, SendGrid, Postmark, Mailgun, or your own mail server — in minutes. All authentication-related emails are then sent through your configuration with full delivery visibility in the dashboard.

Why Custom Email?

Improve deliverability, build trust, and own every touchpoint in your user journey

Brand Consistency

Every email your users receive — password resets, verifications, magic links — comes from your domain, keeping your brand front and centre throughout the entire experience.

Better Deliverability

Sending from a domain with established SPF, DKIM, and DMARC records significantly reduces the chance of your emails landing in spam folders.

Full Visibility

Track every email sent — delivery status, timestamps, and recipient — directly from the AuthAction dashboard. No need to dig through separate provider logs.

  • Custom from address

Secure Credential Storage

SMTP credentials are encrypted at rest and never exposed in API responses, keeping your mail server credentials safe.

  • Encrypted at rest
  • Never returned in API
  • TLS-only connections

Instant Fallback

If your SMTP configuration is removed or fails, AuthAction falls back to the default shared sender so authentication emails are never silently dropped.

  • Zero-downtime switch
  • Automatic fallback
  • No lost emails

How It Works

Connect your SMTP provider in three simple steps

1

Open Email Settings

Navigate to Tenant Settings → Email in the AuthAction Dashboard and click Configure Email.

2

Enter SMTP Credentials

Provide your SMTP host, port, username, password, and the from-address you want to send from (e.g. noreply@acme.com).

3

Save and Go Live

Save the configuration. All subsequent authentication emails for your tenant are sent through your SMTP provider immediately — no restart or deployment needed.

Example SMTP configuration

{
  "host": "email-smtp.eu-west-1.amazonaws.com",
  "port": 587,
  "username": "AKIAIOSFODNN7EXAMPLE",
  "fromEmail": "noreply@acme.com",
  "fromName": "Acme"
}

Credentials are encrypted at rest and never returned in API responses.

Frequently Asked Questions

Common questions about Custom Email

All authentication-triggered emails are routed through your SMTP provider, including password reset emails, email verification codes, and magic link sign-in emails.

AuthAction automatically falls back to the default shared sender, so authentication emails continue to be delivered without interruption. No emails are lost during the transition.
