Frequently Asked Questions

Can the verifier check if an email address is currently receiving mail?

Yes. The software performs an SMTP handshake that confirms the mailbox exists and is able to receive messages, without actually sending an email.

Is my data safe during verification?

All checks are performed locally on your Mac. No address data is transmitted to external servers, ensuring privacy and compliance with data‑protection regulations.

What file formats are supported for import?

CSV and plain‑text (TXT) files are supported. Each line should contain a single email address, or you can use a column header in CSV format.

The trial limits verification to 100 addresses per session. For larger lists, you’ll need to purchase the full license, which removes this restriction.
