Remove Duplicate Lines: Clean Invite Lists
Duplicate addresses in invite lists break bulk sending. This tool scans lines in your browser and finds repeats. Data stays on your device. Back up first; differently spelled addresses count separately.
Step by step
- Back up the list.
- Paste it, enable empty-line removal.
- Set case sensitivity.
- Preview the result and count.
- Copy the clean list over.
Example scenario
A 500-line list holds 80 duplicates. The counter shows 420 unique. Enable ignore-case for variants. Copy the result over; double emails stop.
Check your result
Compare the count with expectations. Trim edge spaces. Confirm key addresses survived. Test-send to a small group.
