Your email is failing a test you can't see.

SPF, DKIM, and DMARC are three DNS records standing between your mail and the inbox. Check yours free — no signup.

That's sendclear.io's own live score — not a mockup, refreshed every few hours. Run the same check on your own domain below.

Your domain — the website address, not an email address (gmail.com, outlook.com, etc. are already set up correctly)

We only read public DNS — never your inbox. Nothing is stored unless you explicitly ask us to email you a copy.

TipSending marketing or transactional email from a subdomain, like mail.yourdomain.com or news.yourdomain.com? Check that separately — it needs its own SPF, DKIM, and DMARC, and a clean result above doesn't cover it.

This isn't optional anymore.

Google and Yahoo now require SPF, DKIM, and DMARC from anyone sending meaningful volume to their users — not a recommendation, an enforced technical bar, with mail increasingly rejected outright if you don't meet it. Most domains still don't.

Google's bulk-sender enforcement began November 2025; Yahoo's rolled out through 2024. Both apply the moment you send to a Gmail or Yahoo address — wherever you or your recipients are.

The problem is silent

SPF, DKIM, and DMARC rarely stop mail from sending outright — they just quietly push it to spam. Here's exactly what each one checks, and what happens when it's missing.

SPF

Lists which mail servers are allowed to send email for your domain. Without it, anyone can forge a message that looks like it's from you.

DKIM

A cryptographic signature added to outgoing mail that proves it actually came from your domain and wasn't altered in transit.

DMARC

Tells inboxes what to do with mail that fails SPF or DKIM — quarantine it, reject it, or let it through — and where to send you reports.

Blacklist

Checks whether your sending domain or IP has been flagged by major spam blocklists, which can silently tank your deliverability.

Frequently asked questions

Is this actually free?

Yes. The instant check is free, with no signup and no card, and we don't store your domain or results — unless you explicitly ask us to email you a copy, in which case we save just enough (your domain and email) to do that.

My email seems to work fine — why would I have a problem?

SPF/DKIM/DMARC issues rarely stop mail from sending outright. Instead they quietly push it to spam, or let it through with a warning banner — the kind of thing you only notice once someone tells you they never got your email.

I got a "Critical" or "Warning" result — what now?

Each result includes a specific fix underneath it — usually a DNS record to add or correct with whoever hosts your domain's DNS.

How is this different from always-on monitoring?

This is a one-time snapshot of right now. Monitoring re-checks daily and only emails you when something actually changes, so you find out the moment a fix breaks or a record expires.

Why do you only check Spamhaus? What about other blocklists?

Spamhaus's Domain Block List is the primary domain-level blocklist — it matches how the rest of this tool works, checking your domain itself. Most other well-known lists (Barracuda, SORBS, and similar) are IP-based, not domain-based, and don't map cleanly onto a domain check — especially if you send through a shared platform like Google Workspace or SendGrid, where the IP isn't really "yours" to check.

What about agency pricing?

Per-domain pricing works for a few domains. If you're managing a full client roster, get in touch and we'll figure out something that fits how you'd actually use it.
