Frequently asked questions

Everything sales teams need to know about email verification.

Yes. Export your prospect list as a CSV and upload it directly. VeriMails automatically maps the email column and processes the entire file in minutes.

When you send to invalid addresses, email providers like Google and Microsoft track those bounces against your domain. Too many bounces trigger spam filters. Verifying first removes invalid addresses so your domain stays clean.

A catch-all domain accepts mail to any address, even ones that do not exist. VeriMails gives each catch-all a probability score so you can decide which ones are safe to send to rather than getting a binary yes/no.

Yes. You can invite team members to your account. Everyone shares the same credit pool and can run their own verification jobs independently.

Most lists complete within minutes regardless of size. A 10,000-row CSV typically finishes in under 5 minutes. You can track progress in real time from the dashboard.
