Build a verified email list
- Names + company
- Domains
- LinkedIn URLs
- Job titles
- Verified work emails
- Verification status
- CSV/XLSX ready to import
A bulk email finder turns a raw prospect list into a verified list of email addresses you can actually use, built from contacts you already targeted rather than a generic list that spikes your bounce rate. Uploaded lists are used only for your own searches, never sold or shared. If your list has been sitting around, it's worth checking how fast an email list decays before you rely on it.

- Mark catch-alls as risky
- May charge for misses
Anymail Finder
- Accepts your file as-is
- Finds domains from company names

Why bulk match rates vary (and what to trust)
Most bulk email finders claim 95%+ accuracy, yet independent tests of the same list show real match rates ranging from roughly 16% to 75%. Here's why the number on the box rarely matches the number that lands.
Typical bulk email finders
- Return old database records
- Count guessed emails as "found"
- Bounce rate is only discovered later
Anymail Finder
- Verifies every email live
- Bills only verified emails
- Coverage reflects emails you can actually send to

Verify a list you already have
Old email lists collect invalid addresses over time. Verify them before sending to protect your sender reputation and improve deliverability.
- Outdated addresses drag down deliverability
- Bounces hurt your sender reputation
- No way to know who's still reachable
- Every address confirmed live
- Invalid emails removed before you send
- Sender reputation stays protected
Verification uses a small amount of credit per check (currently 0.2), since the check runs whether or not the address turns out valid.
