Five statuses, two charged.
The mailbox exists and will accept email. Your list, cleaned.
The mailbox does not exist. Worth knowing before it damages your sender reputation.
The domain accepts any address sent to it, including invented ones. We flag it at no cost. Resolving which specific addresses are real is a separate step.

Bulk Email List Upload
Upload a CSV or XLSX and pick the email column. Each address comes back as verified, invalid, catch-all, risky or unknown, and you pay only for verified and invalid.
Filter by status and export the rows you want. Send catch-alls to resolution from the same list.
Other tools charge for all 2,000 — catch-all and undetermined alike. We don't.
Verification Cache
Free re-checks for 180 days.
Results are cached per account. Re-uploading a list that includes previously verified addresses costs nothing for those addresses — only new ones draw credits.
You can always re-check any address at any time — if the cached result is still within 180 days, it costs nothing. If you want a fresh verification, that's a new check at standard cost.
Your cache is private. Results are not shared across accounts. Cache entries are deleted automatically after 180 days.
Catch-All Emails in Your Verified List
Catch-all domains accept every address you send — real or invented. Standard verification flags the domain and cannot go further. If you need to know which individual addresses on those domains are actually real, that requires catch-all resolution.
