Domain SecuritySend from
your domain
Add a domain and PostFrame lists every record it needs — ownership, three DKIM CNAMEs, SPF, a bounce subdomain and a recommended DMARC — names your DNS host, and checks each record live when you press Check.
All DNS records verified. Your domain is ready to send email through PostFrame.
Guided domain setup
PostFrame walks you through every step. No email authentication expertise required.
Add domain
Enter your sending domain. PostFrame generates the required DNS records instantly.
Copy records
Every record has a Copy button, and the page names your DNS host — Cloudflare, GoDaddy, Namecheap and more — with steps in its own vocabulary.
Check
Press Check and every record is resolved live: found, missing or mismatch, with a hint. The first time a domain becomes fully verified you get an in-app notification.
Start sending
Add sender addresses on the verified domain and send from them — through the managed pool or a provider you bring.
Three layers of authentication
Sender Policy Framework
Declares which servers are authorized to send email on behalf of your domain. Prevents spoofing and improves inbox placement.
How SPF works
DomainKeys Identified Mail
Cryptographically signs your emails so recipients can verify the message hasn't been altered in transit.
How DKIM works
Domain-based Auth
Tells receiving servers what to do with emails that fail SPF or DKIM checks. Includes aggregate reporting for monitoring.
How DMARC works
Domain verification, answered
Which DNS records does a domain need?
An ownership TXT record, three DKIM CNAMEs, an SPF TXT record, and an MX plus SPF record on the bounce subdomain. A DMARC record is listed as recommended. The setup page shows each one with a Copy button.
How long does verification take?
As long as DNS propagation at your host. Press Check any time; each record is resolved live and reported as found, missing or mismatch with a hint, and the domain is verified once every required record is found and the provider confirms DKIM.
Can two workspaces use the same domain?
No. A domain is claimed by one workspace across the platform; a second workspace that tries to add it is refused with a clear message. Deleting the domain releases the claim.
Which domains cannot be added?
Public mailbox providers such as gmail.com and platform domains are refused by policy, because nobody can publish DNS records for them.
