Why we find emails others can't.
Most tools stop at the easy addresses. We verify the harder cases live, so we find emails they return as "risky", "unknown", or "not found".
Most tools
- Read from a database that has gone stale
- Skip catch-all domains as risky
- Pad the number with guesses
Anymail Finder
- Live, not cached. Every address is verified against the recipient's mail server.
- Catch-alls verified. We confirm the addresses others skip.
- No guesses counted. We only report addresses that pass live verification.
More verified emails. Fewer bad ones.
In a 14-tool benchmark on the same 5,000 B2B contacts, we found verified emails for 86.4% at 98.9% accuracy. Your rate depends on your list: B2B companies come back highest, local businesses, nonprofits and government lower.
FAQs
Do you store my list?
We only use your file to run the coverage test and email your results. We never sell or share uploaded data, and uploads are handled under the same GDPR-compliant process as the rest of Anymail Finder.
Will you email the contacts in my list?
No. We only use your file to run the coverage test and send the results to you. We never contact anyone on your list.
How does the coverage test work?
Upload a CSV or Excel file with up to 5,000 rows. We run every contact through our live finding-and-verification pipeline, then email you the result in a few minutes: your coverage rate (the share of your list that came back with a verified email) and the number of verified emails found.
How big a list can I test?
The free coverage test accepts up to 5,000 rows per upload, enough for a solid read on your data. For larger lists or ongoing volume, you can run the full list once you have an account.
Will it work on my list?
Most lists do. The test auto-maps your columns and supports person, company, and decision-maker searches. You can upload standard CSV or Excel exports from Sales Navigator, your CRM, or an enrichment tool.
What is a good email coverage rate?
It depends on the list. Lists of established B2B companies come back highest; local businesses, nonprofits and government lists come back lower with any tool. The useful comparison is how another tool does on the same list.
Why do other tools miss emails you find?
They rely on databases that go stale as people change jobs, and they often flag catch-all domains as "risky" instead of checking them live. That leaves real, reachable contacts out of your results.
