# Add Domain

Adding and verifying a custom domain is the first step to sending production email with Mailofly.

A verified domain gives you:

* **Custom Sender Identity**: Send branded emails from addresses like `support@yourdomain.com` or `newsletter@updates.yourdomain.com`.
* **Cryptographic DKIM Signing**: Your emails are signed with 1024/2048-bit DKIM keys through our delivery relay, proving authenticity.
* **SPF & DMARC Alignment**: Prevents spoofing, improves sender reputation, and ensures your emails reach the primary inbox rather than spam.
* **Open & Click Tracking**: Track user engagement through branded tracking links.
