Common errors and fixes
Role or test emails remain in the output
The cleaner normalizes syntax and duplicates, but it does not decide whether an address is appropriate for your campaign.
Filter role accounts, internal test addresses, and unsubscribed contacts before sending.
Deliverability still needs checking
A syntactically valid email can still bounce or belong to an inactive mailbox.
Use this tool for cleanup, then run deliverability checks in your email platform when campaign risk is high.
When to use Email List Cleaner
