Why it matters

Upload a CSV and clean the entire list in minutes — email verified, phone validated, duplicates removed — then download a file you can send or import with confidence.

Bulk cleaning runs the full verification engine across an entire file at once — email, phone, dedupe — and hands back a list you can send or import with confidence. It's the workhorse behind every pre-campaign clean.
