Questions worth asking
Everything people ask before sending us their first list.
Every deliverable result comes from a real SMTP conversation with the domain's mail server, not a guess. Where a server refuses to answer honestly — a catch-all domain, or one that blocks probing — the address comes back as risky rather than being passed off as valid.
A CSV with a column named "email". Every other column is preserved and returned alongside the results, so your names, IDs and tags stay attached to the right rows.
They are left out. They are not verified, not counted in your totals and not included in the result file — so your deliverable rate reflects the addresses you actually have.
Verification runs in the background with live progress. Results for repeated domains are reused within a run, so large lists move considerably faster than the address count alone suggests.
Your uploaded file and its results stay in your account so you can download them again. Delete your account and both go with it.
