What this check looks at
Two of the three email records that Gmail uses to decide if your newsletter is really from you. DMARC: is there exactly one record at _dmarc.yourblog.com? SPF: is there exactly one SPF record, and does it stay within 10 DNS lookups, counting the includes inside includes?
What this check cannot see
DKIM, the signature your newsletter tool adds to each email. Its record sits under a name chosen by your tool, so no outside check can find it for sure. To check DKIM, send a test email from your newsletter tool to a Gmail address and choose 'Show original' in Gmail. Look for dkim=PASS.
Why it matters
Google says senders of more than 5,000 messages a day to Gmail accounts must use SPF, DKIM and DMARC, and that mail that fails might be marked as spam or rejected with a 5.7.26 error. Every sender must use SPF or DKIM.
Your privacy
The check runs in your browser. Your browser asks a public DNS service (Cloudflare DNS or Google Public DNS) for the domain's public records. We do not store the domain, and this site sets no cookies.
We fix it with you, and you pay after it works. If it does not work, you pay nothing.
We want to be your technology partner. We do not want to take your money for work that does not help.
