Frequently asked questions
How do I remove one email list from another?
Paste your main list in the first box and the addresses you want gone — unsubscribes, bounces, opt-outs — in the second. The cleaned list appears instantly, with every address from the second list taken out.
What format should the lists be in?
One address per line or comma-separated, or a mix of both. Extra spaces are trimmed automatically.
Is it case-sensitive?
No. Addresses are compared in lowercase, so [email protected] and [email protected] count as the same address. Duplicates in your main list are removed too.
Is my data private?
Yes. The filtering runs in your browser, so your lists never leave the page. (If JavaScript is turned off, they are sent once to our server to be processed and are not stored.)
