Upload your list, download it clean
Upload a CSV, TXT or XLSX file. Every address is sorted into safe, risky or don't send and gets a 0-100 score. The clean list is one click away.
A clear call on every address
Each address goes through a syntax, domain and mail server check in turn. You see the outcome on one screen.
Result splitSee at a glance how much of your list is safe to send.
Confidence scoreEvery address gets a 0-100 score, so borderline ones show up as a number.
Live progressNo refreshing on big lists. Progress updates on its own.
Clean exportDownload the safe addresses, or any group you pick, as CSV or XLSX.
Stop bounces before you send
Every email sent to a dead address bounces. As your bounce rate climbs, mailbox providers push your mail into spam, and your good addresses stop seeing it too.
Clean the list first and bad addresses never make it into the campaign. You decide what to do with the risky ones.
Frequently asked questions
CSV, TXT and XLSX, up to 100,000 rows and 25 MB per file. We find the email column for you, and you can pick another one if we guess wrong.
Each unique address we check costs 1 credit, even when the result is Unknown. Duplicates in the list are free. If a row can't be checked because of an error on our side, its credit comes back.
Some mail servers say yes to every address, others block the check. When we can't be sure, the address gets Unknown. A wrong "safe" would come back to you as a bounce.
The list, its results and the report are deleted for good 30 days after upload. You can delete them yourself any time before that.
