Take the dead weight out of your list before you pay anyone to verify it.

Paste the addresses. The page finds duplicates, broken syntax, role inboxes, disposable domains and the four typos everyone makes. It runs in your browser. Nothing leaves this tab, nothing is stored, and there is no box to tick.

Free, no signup

What this cannot tell you, and will not pretend to.

Whether the mailbox exists That takes an SMTP conversation with the receiving server, and this page never talks to one. What you get back is the list worth sending to a verifier. Everything removed here you would have paid to be told about.

Whether the person still works there Nobody can tell you that from an address. A bounce will, which is why the first send matters more than the check.

Anything about your data The list is read by JavaScript in this tab and thrown away when you close it. There is no upload, no account, no cookie and no log. Open the network tab and watch.

Whether a role inbox is a bad idea Often it is the only address a small studio has. That is why it is a toggle and not a rule.
