Custom email delivery with your own SMTP provider
Scalekit Full Stack Auth now supports external email providers, so you can send auth-related emails—like magic links, signups, and invitations—directly from your domain.
This gives you full control over deliverability, branding, and compliance.
Why use your own provider
- Send from your own domain
- Meet compliance standards like GDPR and CCPA
- Integrate with existing email analytics
- Improve inbox trust and deliverability

How it works
In your Scalekit dashboard:
- Go to Emails
- Select Use your own email provider
- Add your SMTP settings:
- Host, Port, Username, Password
- From address and sender name
- Save and test configuration
Works with any SMTP provider including SendGrid, SES, and Postmark.
What to check
- Delivery to test addresses
- Sender name and email
- Branding and formatting
- Link behavior in real clients
