Upload a main list and a suppression list. Match by phone, email, or custom columns and download both the remaining file and the suppressed rows file.
The suppression file contains the numbers/records to remove (e.g. DNC list, opt-outs, existing customers).
This is the file you want to clean โ rows matching the suppression list will be removed.
Outputs include a remaining file and a suppressed-rows file. Both files are stored privately.
