Sending Domains

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.
