Questions
- How many checks do I get for free?
- Every new account gets 5,000 bonus checks, enough to clean a first list, plus a small monthly allowance.
- Do credits expire?
- No. Checks bought as a pack never expire and are used after your monthly allowance runs out.
- Do you email the people on my list?
- Never. We ask each mail server whether the mailbox exists and hang up before any email is sent.
- How long does a list take?
- Most lists of a few thousand addresses finish in minutes. You can close the tab: we'll keep working and you can download the results when they're ready.
- What should I do with risky addresses?
- Risky means disposable, a role address like info@ or a server that accepts everything. Keep them out of cold campaigns, and send to them carefully elsewhere.
