What “clean” means here
The list cleaner checks address syntax, domain existence, MX records, disposable-domain risk and common role inboxes. It intentionally does not run SMTP mailbox probing in bulk, which keeps the tool fast and avoids presenting uncertain mailbox behavior as a hard fact.
For one address where mailbox-level signals matter, use the deliverability checker.
