About this tool. Classic ICMP ping can't be sent from a serverless edge, so we measure the next best thing honestly: full HTTPS round-trip time to the host, three times in a row. It answers the same question — is the host up, and how far away does it feel.
Ten signals decide whether your mail arrives. You just checked one.
Latency is about reachability. Deliverability is about trust, and a fast server with no SPF record still lands in spam.
- SPF, DKIM, DMARC, MX and blocklist status, graded A to F in one pass
- Every problem written out in plain English, with the record to publish
- Saved under Reports, so you can re-run it and see what changed
- One domain watched against the blocklists daily
Run the full checkup free
No card, and nothing to cancel.
How to read your Ping & Latency results
- We measure round-trip time from our edge to the host you enter. Lower is faster.
- This reflects the path from our network, not from your own location, so treat it as a relative signal.
Common problems and how to fix them
Latency is unexpectedly high
High round-trip time can mean a distant server, network congestion, or an overloaded host. Compare against a known-fast host to calibrate.
Common questions.What does the latency test measure?
The round-trip time from our edge network to the host you specify.
Is this the same as ping from my computer?
Similar idea, but measured from our servers, so absolute numbers differ from a ping on your own machine.
