SPF, DKIM & DMARC checker
Enter a domain and we will look up its SPF, DMARC, DKIM and MX records — the four settings that decide whether your email reaches the inbox or the spam folder.
gmail.com
Some settings need attention.
SPF
WarningSPF record has no hard fail
The record does not end with -all or ~all, so it has little effect. Add -all (strict) or ~all (soft) as the last mechanism.
Records found
- v=spf1 redirect=_spf.google.com
DKIM
WarningNo common DKIM key found
No DKIM key was found under the common selectors for gmail.com. This may simply mean your provider uses a different selector — check your mail host's documentation. Common selectors checked: google, zoho, selector1, selector2, default, mail, smtp, s1, s2, k1, dkim, key.
DMARC
WarningDMARC policy is p=none
p=none only monitors and takes no action. That is a fine starting point — move to p=quarantine once you have reviewed the reports.
Records found
- v=DMARC1; p=none; sp=quarantine; rua=mailto:mailauth-reports@google.com
MX records

What do these records mean?
SPF, DKIM and DMARC prove your email really comes from your domain. Mailbox providers check them to decide whether to trust you. Fix the warnings above, then wait a few hours for DNS to update and run the check again.
Hosting mail on Zoho Mail? Keep an eye on the MX and DKIM checks above — both must be configured at your domain registrar for mail to flow and to stay out of spam.
