No DKIM key found on your domain — how to add one
WHAT YOU'RE SEEING
A DNS check reports "no DKIM key found" across the common selectors.
WHY IT'S HAPPENING
You've never set up DKIM, or you're using a sending provider that signs with their own domain instead of yours.
How to fix it
- 1
Identify your email sending provider (Gmail/Workspace, Microsoft 365, SendGrid, Mailgun, etc).
- 2
In that provider's admin console, look for "DKIM", "Email Authentication", or "Sender Authentication".
- 3
Generate a DKIM key for your domain.
- 4
The provider will give you a TXT record (or CNAME). Add it to your DNS.
- 5
Wait 30 minutes, then verify in the provider console.
Where do I add these records? (by DNS host)
Records go in the DNS panel of whoever hosts your domain, not inside Gmail or Outlook. Find your host below.
