What this email deliverability test checks
SPF
Is there exactly one SPF record? Does it stay under the 10-lookup limit and end with ~all or -all?
DKIM
We probe 55+ common selectors (Google, Microsoft, Mailchimp, SendGrid…) and flag weak 1024-bit or revoked keys.
DMARC
Is _dmarc published? Policy, reporting address and alignment, which are needed to meet the Gmail & Yahoo bulk-sender rules.
Since February 2024 Google and Yahoo reject or spam-folder mail from domains without proper authentication. If your invoices, quotes or newsletters "disappear", a missing DMARC record or broken SPF is the usual reason. This checker gives you a plain-English grade and the exact records to paste into GoDaddy, Cloudflare, Namecheap or any DNS host.
FAQ
Is it really free?
Your first check each day is free and shows your grade, pass/fail for SPF, DKIM and DMARC, and your top issue. Full reports with fixes use credits.
Do I need an account?
No. After you buy, you get an access key (shown on screen and emailed to you). It's saved in this browser automatically.
Can I check client domains?
Yes. Agencies and IT consultants use the Agency pack to audit client domains before campaigns.
Do you send email or change my DNS?
No. We only read public DNS records. Nothing is sent from or changed on your domain.
Refunds?
If a pack doesn't help, email us within 14 days for a full refund.
