Strengthen the DMARC policy
Quarantines all mail that fails DMARC. Move on to reject once the reports stay clean. Changes: pct applies to sp as well, so a pct=25 ramp would enforce sp=quarantine on only a quarter of subdomain mail. The ramp is skipped to keep subdomains fully protected; p moves to quarantine directly.
_dmarc.gmail.com
Some DNS providers want just “_dmarc” here.
v=DMARC1; p=quarantine; rua=mailto:mailauth-reports@google.com; adkim=r; aspf=r
v=DMARC1; p=none; sp=quarantine; rua=mailto:mailauth-reports@google.com
How to apply it
- Sign in where your domain’s DNS is managed. This is often where you bought the domain, such as Cloudflare, GoDaddy or Namecheap.
- Find the existing TXT record with that name and replace its value.
- Save, then come back and re-check. DNS changes can take up to a few hours to show.

MXCan servers find your inbox?No issues foundPass
Nothing to report.
SPFWho may send as you?SPF ends in softfail (~all)Info
- Info: SPF ends in softfail (~all)
"~all" is common and works well with DMARC. "-all" is stricter; switch when you are sure every sender is listed.
DKIMAre your emails signed?No DKIM key found for the common selectorsNeeds attention
- Warning: No DKIM key found for the common selectors
None of the 47 selectors probed under gmail.com publish a DKIM key. DNS cannot list selectors, so a key under a custom selector may exist: find the s= value in the DKIM-Signature header of a message you sent and check that selector. If DKIM is not set up, enable it at each service that sends mail for gmail.com.
DMARCWhat happens to fakes?DMARC policy is noneNeeds attention
- Warning: DMARC policy is none
A none policy only monitors: mail that fails DMARC is still delivered, so anyone can spoof the domain. Once reports show your legitimate senders pass, move to quarantine and then reject.

- Info: No BIMI record
No BIMI record at default._bimi.gmail.com. BIMI is optional: it shows your logo next to your mail in supporting inboxes once DMARC is enforced.

Other fixes
Enable DKIM for Google Workspaceinstruction
Google Workspace generates the DKIM key for each account, so the exact record must come from Google Workspace. Without DKIM, mail it sends for gmail.com cannot pass DMARC through DKIM.
Applies to: google._domainkey.gmail.com
- In Google Workspace, enable DKIM signing for gmail.com: Generate the key in Admin console > Apps > Gmail > Authenticate email, then publish the TXT record shown there. Publish exactly the record Google Workspace shows (TXT or CNAME) at the host name it gives, then turn signing on. Instructions: https://support.google.com/a/answer/174124
Prepare BIMIinstruction
BIMI shows your logo next to messages in supporting inboxes, but only for mail that passes DMARC under an enforced policy.
Applies to: default._bimi.gmail.com
- Enforce DMARC first: p=quarantine or p=reject at 100% (no pct below 100). 2. Convert your logo to an SVG Tiny PS file and host it over HTTPS, for example https://gmail.com/bimi/logo.svg. 3. For Gmail and Apple Mail, obtain a VMC or CMC certificate for the logo. 4. Publish a TXT record at default._bimi.gmail.com with v=BIMI1, l= set to the logo URL and a= set to the certificate URL.
