# Sending Domains

> Send from a domain you own, buy a new domain, or start with a Migma address.

Sending domains control the address your recipients see and the reputation attached to your email. Use a verified domain before production campaigns whenever possible.

Migma supports three setup paths:

* **Use my domain** for a domain you already own. Migma prepares records and opens Entri one-click DNS setup when available.
* **Buy a domain** for a new sender registered from Migma.
* **Start with a Migma address** for a managed `migma.email` sender without DNS setup.

## What Migma sets up

* Domain ownership verification
* DKIM signatures
* SPF authorization
* DMARC policy
* Custom MAIL FROM for bounce handling
* Domain health, metrics, email logs, and warming

## Common use cases

* Send campaigns from `hello@yourbrand.com`
* Isolate marketing reputation on `mail.yourbrand.com`
* Buy a new sending domain for a new brand or campaign line
* Start quickly with a managed Migma address for tests or API workflows
* Warm a new domain before larger sends

## Best practices

**Use a domain users recognize.** Sender identity affects trust and complaints.

**Prefer a dedicated sending subdomain.** `mail.yourbrand.com` or `updates.yourbrand.com` can separate campaign reputation from company inboxes.

**Use one-click DNS when available.** Entri and Cloudflare setup reduce copy-paste DNS mistakes.

**Warm new domains.** Increase volume gradually before sending to a full list.

**Watch health and logs.** Bounces, complaints, and failed delivery show reputation risk early.
