Will your email reach the inbox?
Check your domain against what Gmail, Yahoo, Outlook and every major inbox expect — and find out if you’re at risk of landing in spam, getting blocked, or having your sending account paused.

What we check for you
Everything that decides whether your emails reach the inbox — explained in plain English, with a clear fix for anything that needs attention.
Are you allowed to send? (SPF)
We check that your domain officially lists which services are allowed to send email for you. If it’s missing or set up wrong, inbox providers get suspicious and your mail can land in spam. We tell you in plain words what to add.
Is your mail signed as genuine? (DKIM)
Real senders add an invisible “signature” to every email that proves it truly came from you and wasn’t tampered with. We look for yours across the common setups (Amazon SES, SendGrid, Mailgun, Postmark, Mailchimp and more) and tell you if it’s missing.
Are you protected from impersonation? (DMARC)
This is the rule that stops scammers from sending fake emails “from you.” We check whether it’s published, whether it’s actually doing its job (not just watching), and whether you’re getting the reports that show who’s pretending to be you.
Can you receive replies and reports?
We make sure your domain is set up to receive mail — needed for bounce messages and the reports that keep your sender reputation healthy. We also explain the reverse-DNS requirement Gmail and Yahoo expect from your sending server.
Is your domain on any blocklists?
We check your domain (and, with a test email, your sending server) against the big email blocklists that mailbox providers trust. Being listed quietly kills your delivery — and we link you straight to the removal page if you are.
Do you meet the new Gmail & Yahoo rules?
Since 2024, Gmail and Yahoo require bulk senders to be properly set up — sign-offs, an unsubscribe link people can click once, and a low spam-complaint rate. We turn the whole checklist into a simple pass/fail you can actually act on.
Are you at risk of getting paused?
Services like Amazon SES, SendGrid and Mailgun will pause your account if too many emails bounce or get marked as spam. We show you the exact limits they act on, so you know how much room you have before trouble.
Want a real-world check? (optional)
A quick scan can’t see everything. Send one email to the address we give you and we’ll inspect it to confirm your sending server, signatures and reputation are genuinely working — for real. We don’t store your email.
How it works
Enter your domain
Just the domain (or an email address — we’ll extract it). No signup, no email gate.
We scan public DNS
SPF, DKIM, DMARC, MX, reverse-DNS guidance and blacklists — in a few seconds.
Get a verdict + fixes
One score, grouped PASS/WARN/FAIL, and a copy-paste DNS record with a re-check button for every issue.
The honest limit — and why it matters
A one-time external scan shows your configuration. But the things that actually get you blocked or paused — your live bounce rate, complaint rate, and who is spoofing your domain — are ongoing and only visible from inside your mail stream. We never fail you on something we can’t truly observe, and that’s exactly where continuous monitoring comes in.

What are the Gmail and Yahoo sender requirements?
Since February 2024, bulk senders (roughly 5,000+ messages a day to Gmail) must authenticate mail with SPF and DKIM, publish a DMARC policy, use one-click unsubscribe with a visible unsubscribe link, send from a domain with valid forward and reverse DNS, and keep their spam complaint rate under 0.1%. This tool checks the parts that are visible in DNS and clearly flags the two that aren’t.
How do I check if my domain passes SPF, DKIM, and DMARC?
Enter your domain above. We read your published DNS records and report whether each is present and correctly configured: a single valid SPF record, a discoverable DKIM key, and a DMARC policy — along with a plain-English meaning and a copy-paste fix for anything that fails.
Why are my emails going to spam?
The most common causes are missing or broken authentication (no DKIM, multiple SPF records, a too-weak DMARC policy), poor sending-IP reputation or a blacklisting, a high bounce or complaint rate, and a cold/new domain. This checker surfaces the configuration issues instantly; the live bounce and complaint rates that also drive spam placement are visible only from inside your mail stream.
What bounce rate gets your AWS SES account suspended?
AWS puts your SES account under review as your bounce rate approaches 5% and can pause sending at 10%. Complaint rates are reviewed at 0.1% and can pause sending at 0.5%. We show these thresholds, but we can’t read your live rates from outside — connect ParseBounce to monitor them in real time.
Do I really need both SPF and DKIM?
Yes. Gmail and Yahoo require both for bulk senders, and DMARC only passes when at least one of SPF or DKIM is aligned with your From domain. Setting up both is the single most reliable way to stay out of spam.
What is a good DMARC policy?
Start at p=none with a rua address so you can collect reports and see who sends as you, then move to p=quarantine and finally p=reject once legitimate sources pass. p=none alone is monitoring-only — it doesn’t protect your domain from spoofing.
Is this deliverability checker free?
Yes — completely free, no signup and no email gate to see your results. Each scan also gets a shareable URL so you can bookmark or send it.
Can you check deliverability without sending a test email?
Yes. The instant scan uses only public DNS, so you get a full report without sending anything. The optional test email is there when you want to verify the things DNS can’t show — your real sending IP, SPF/DKIM alignment and reverse DNS.
