Verify your own sending domain
Four DNS records, and your mail is provably yours.
Add your domain in Settings and we give you four DNS records to publish. Once they resolve, your mail is signed as your own domain — the strongest thing you can do for deliverability, and it raises your daily sending limit furthest.
Adding it
Add the domain
Use the domain you actually want in the From address. A subdomain like
mail.yourcompany.comis fine and is what many senders prefer.Publish four records
Three CNAMEs that let us sign your mail, plus one TXT that proves the domain is yours. Copy them exactly.
Wait, then check
DNS usually propagates in minutes but can take hours. Press Check DNS rather than waiting to be told.
Why four records, not three
The three CNAMEs let us sign mail for your domain. The TXT proves you control it — and it’s not redundant.
A real problem it prevents
Signing infrastructure is shared, so a domain that some other account verified previously can look already-verified to us. Without a check that asks the domain rather than our own records, someone could claim a domain they don’t own by typing it in. The TXT closes that.
The two things that go wrong
Your provider appends the domain. Many DNS panels add your domain to whatever you type in the host field. Paste abc123._domainkey.yourcompany.com and you may end up with abc123._domainkey.yourcompany.com.yourcompany.com. After saving, look at what the panel displays rather than what you typed.
Cloudflare’s proxy is on. A proxied CNAME (orange cloud) resolves to Cloudflare instead of returning the target, so verification never completes and nothing looks wrong. These records must be DNS only — grey cloud.
Common issues
Still pending after hours
Check for the appended-domain mistake above, then check Cloudflare’s proxy is off. Those two account for nearly every case.
Some records verified, one didn't
Usually a copy-paste that clipped a character. Re-copy the failing one and compare it end to end.
My domain is used for email already
That’s fine and normal. These records don’t affect your existing mail — they add permission for us to sign alongside it. They don’t touch your MX records.
I can't edit DNS
Use a free sending address on our domain instead. It works instantly and needs nothing from you.
FAQs
Will this affect my normal email?+
No. The records only add signing permission; your MX records — which decide where your incoming mail goes — aren’t touched.
Can I use the same domain on two platforms?+
Yes, and you should while migrating. Each publishes its own records and they coexist.
What if I remove the domain later?+
Your account stops using it. You can then delete the DNS records at your leisure — leaving them does no harm.
