Sending domains control the address your recipients see and the reputation attached to your email. Use a verified domain before production campaigns whenever possible. The workspace owner or a manager on all brands can add and manage sending domains. A manager on one brand can send from a ready domain, but cannot change account DNS. 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. Eligible new accounts receive one after email verification; you can also add one from Sending Domains.

​
What Migma sets up

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

​
Choose the address recipients see

When you connect a domain, Migma verifies two sending identities:
  • yourbrand.com for campaigns and anything you send by hand
  • notify.yourbrand.com for transactional email
Receipts and password resets stay on their own address, so a rough campaign cannot take them down.
  • Add a From address on the identity you want recipients to see. hello@yourbrand.com lives on the main domain. hello@notify.yourbrand.com lives on the transactional identity. SES verifies each identity separately, so one does not inherit the other. Publish lists every sendable identity you have a From on.
  • Sends from the main domain use your main domain’s reputation, for both types of email. The transactional address keeps receipts isolated.
  • Unsubscribe handling, suppression, and compliance follow the type of email you send, not the address you pick.
If a domain you connected earlier still has send.yourbrand.com, that address keeps working and still appears as a marketing sender. New domains do not create it.

​
Common use cases

  • Send campaigns from hello@yourbrand.com
  • Show your bare domain in the inbox with a verified main domain sender
  • 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 you own before larger sends

​
Best practices

Use a domain users recognize. Sender identity affects trust and complaints. Prefer the transactional address for receipts. notify.yourbrand.com keeps password resets and order email off your campaign reputation. Choose the main domain sender when inbox recognition matters more. Use one-click DNS when available. Entri and Cloudflare setup reduce copy-paste DNS mistakes. Warm new domains you own. Increase volume gradually before sending to a full list. Migma addresses use a fixed daily limit and do not warm. Watch health and logs. Bounces, complaints, and failed delivery show reputation risk early. Watch the account sending limit. Daily and monthly counts sit on Sending Domains. When the limit is reached, Campaigns still lets you prepare emails. Sending waits until the limit resets, or you increase limits.
