# Why Verify a Domain?

To ensure high deliverability and prevent spam, Simple Email API processes emails only from verified domains.

## The Benefits

* **Send from Any Address**: Once you verify `example.com`, you can send from `hello@example.com`, `support@example.com`, or any other address—no separate verification needed.
* **Root & Subdomains**: You can verify your root domain (`example.com`) or a subdomain (`mail.example.com`).
* **Brand Identity**: Your emails will show as coming directly from your domain, building trust with your users.
* **Deliverability**: Verified domains use SPF, DKIM, and DMARC to authenticate your emails, landing them in the inbox, not the spam folder.

## How it Works

1. **Add Domain**: Tell us which domain you want to use.
2. **Configure DNS**: Add a few records to your DNS provider (e.g., Cloudflare, GoDaddy).
3. **Verify**: We check the records, and once verified, you're ready to send!
