Frequently Asked Questions

Do you send any emails during validation?

No, we never send actual emails. We only perform polite SMTP handshakes to verify mailbox existence without sending any content.

What file formats do you support?

We support CSV files with email addresses in any column. The validator will automatically detect and process email columns.

How accurate is the validation?

Our validation achieves 99%+ accuracy by combining syntax checks, DNS validation, and SMTP probing. Some providers (like Gmail) may hide mailbox existence for privacy.

What do the validation results mean?

Valid: Email exists and can receive mail. Invalid: Email doesn't exist or domain rejects mail. Unknown: Couldn't determine (often due to provider restrictions). Catch-all: Domain accepts any email address.
