Domains
Live email is only sent from domains you have verified. Verification proves you control the domain and sets up the authentication mailbox providers check.
Records to publish
Add the domain under Domains in the dashboard. Mailfy generates a DKIM key for it and shows these records with their exact values:
| Purpose | Type | Name | Required |
|---|---|---|---|
| DKIM signature | TXT | <selector>._domainkey.<domain> | Yes |
| SPF for the return path | TXT | send.<domain> | Yes |
| Return path (bounces) | MX | send.<domain> | Yes |
| DMARC policy | TXT | _dmarc.<domain> | Recommended |
Records go on a send. subdomain and a unique DKIM selector, so they don’t conflict with your existing SPF or mail provider. Start DMARC at p=none and tighten it once your reports look clean.
Verification
Click Verify after publishing, or wait: pending domains are re-checked every 5 minutes for 72 hours, verified domains daily. DNS can take from minutes to a few hours to propagate. If a lookup times out the status is left unchanged rather than failing the domain.
The DKIM private key is generated by Mailfy and stored encrypted; you only ever publish the public key. Outgoing mail is DKIM-signed with d= your domain.
Plan limits
Free includes one sending domain. Higher plans include more; see Pricing.
