1. Your list
Or paste rows (with or without a header row):
2. Checks
Trim spaces, lowercase, pull addresses out of text like Ava Martin <ava@example.com>
Remove exact duplicates (first one kept)
Flag broken formats (missing @, bad characters, missing .com)
Suggest fixes for common domain typos (gmial.com → gmail.com)
Pro adds domain mail-record checks, role-address and throwaway-domain flags, and automatic typo fixes.
What this does not do: ListScrub does not connect to mail servers or check whether an individual mailbox exists, so some “clean” addresses may still bounce. Use it to tidy a list before import; for the leftover uncertain addresses, a dedicated verification service can do deeper checks. Only email people who agreed to hear from you — following email and privacy laws is your responsibility.
