Frequently asked questions

What file format should I use?

CSV or Excel is the best fit for bulk verification (.csv, .xlsx, .xls, .xlsm).

Can I verify cold outreach lists?

Yes. The goal is to reduce bounce risk before contacts are added to a sending campaign.

Will risky emails be removed automatically?

No. Bulk verification should classify them so your campaign team can decide whether to suppress or segment them.
