Deliverability
The inbox is decided before you press send
Mailbox providers judge your DNS, your authentication and your reputation long before they look at your subject line. These three tools show you all three, and tell you when one of them breaks.
The suite
Three tools, one question
Each one answers a different part of “will this message arrive?” — and each one works on its own.
How it fits together
Clean the list, build the reputation, monitor inbox health
In that order. Each step is wasted without the one before it, and undone over time without the one after it.
- Step 1
Clean the list
Bounces are the fastest way to lose a sending reputation. Validation removes the dead addresses, spam traps and typo domains before a campaign ever goes out, so your bounce rate stays where providers expect it.
Validation credits - Step 2
Build the reputation
A clean list only helps if receivers can tell the mail is really yours. Fix MX, SPF, DKIM and DMARC once, get the score up, and your authenticated mail starts being treated as authenticated mail.
Test your domain - Step 3
Monitor inbox health
Reputation decays quietly. A blocklist listing, an expired DKIM key or a new sender spoofing your domain all happen between campaigns — monitoring is what turns those into an email to you instead of a quarter of missing replies.

Versus doing it by hand
You can do all of this yourself. The question is whether you will keep doing it.
Nothing here is secret knowledge — it is DNS lookups and XML. The value is that it happens on a schedule, and that somebody tells you when the answer changes.
| The job | By hand | With PilotVerify |
|---|---|---|
| Checking DNS records | dig by hand, one record at a time, then read the RFCs to work out whether the answer is right. | One test reads nine checks and tells you which ones cost you delivery, in priority order. |
| Watching blocklists | Remember to look. In practice, you find out when a customer says they never got the invoice. | Scheduled checks against Spamhaus ZEN, DBL and ZRD, with an email the moment a listing appears. |
| Reading DMARC reports | Zipped XML from a dozen receivers landing in a mailbox nobody opens. | Parsed into sending sources, pass rates and a policy recommendation you can act on. |
| Proving it to somebody else | Screenshots, a spreadsheet, and a lot of explaining. | A history per domain you can point at, showing the score moving and when each listing cleared. |
We do not offer seed-list inbox placement testing, mailbox warmup or email finding. If those are what you need, another vendor will serve you better — see the full comparison on the pricing page.
FAQ
Questions about the deliverability suite
If something here is not clear, ask us — we would rather answer than have you guess.
Do I need an account to use these tools?
No for the one-off checks. The email server test and the blacklist lookup are free public tools with a per-IP rate limit and no signup. An account is what lets us keep the history, watch your domains on a schedule, and email you when something changes.
Is this different from email validation?
Yes, and you want both. Validation cleans the addresses you send to, which protects your bounce rate. Deliverability monitoring watches the domain you send from — its DNS, its reputation and its authentication. A clean list sent from a broken domain still lands in spam.
Will any of this affect my live mail?
No. Every check is a DNS lookup, plus one HTTPS request for an MTA-STS policy file when that record exists. We never connect to your mail server over SMTP and never send test messages, so nothing we do touches mail flow or reputation.
Do you test inbox placement or warm up mailboxes?
No. We do not offer seed-list inbox placement testing or mailbox warmup, and we would rather say so than imply otherwise. What we cover is the DNS, authentication and reputation side — the part that is objectively measurable and that you control.
How much does it cost?
The server test is free and unlimited. A free account includes one DMARC domain, three blacklist monitors and seven days of history. Paid deliverability plans start at $9 a month and are currently in beta, which means free to use while the beta runs.

Test the domain you send from. It takes about ten seconds.
No card, no trial clock. The free workspace keeps one DMARC domain, three blacklist monitors and seven days of history — enough to find out whether you have a problem.
