What is the Email Verifier?

The Email Verifier checks your email list before you send a campaign. Upload a CSV and LeadsFriday runs the addresses through MillionVerifier to identify valid, invalid, risky, and other verification results.

What email verification results will I get?

Your completed CSV includes the original email addresses along with their verification results, so you can quickly separate safer addresses from invalid, risky, or uncertain ones before sending.

How do I verify an email list?

Upload your CSV, map the column containing the email addresses, and submit your request. We process the list and return a CSV with the verification results added.

Why should I verify emails before sending?

Email verification helps identify bad addresses before they become bounces. Cleaning your list can reduce unnecessary bounces, protect your sender reputation, and give your outreach campaigns a cleaner starting point.

Does LeadsFriday use MillionVerifier?

Yes. Email verification requests are processed through MillionVerifier, giving you established verification data without needing to upload and process the list there yourself.

Can I verify a large email list?

Yes. You can verify anything from a small prospect list to a CSV containing thousands or millions of email addresses. Larger files may take longer to process.

How long does email verification take?

Processing time depends on the size of your list. Smaller lists can finish quickly, while large bulk email verification requests may take longer. You don’t need to keep the page open while your request is processing.

Will email verification guarantee zero bounces?

No email verification service can guarantee that every verified address will deliver. Mailboxes can change after verification, providers can behave differently, and other factors can affect delivery. Verification helps reduce bounce risk rather than eliminate it completely.

Will my original CSV data be preserved?

Yes. Your existing rows and data remain in the finished file, with the verification results added so you can filter and use the list without rebuilding it.

How much does the Email Verifier cost?

The cost depends on the number of email addresses you verify. You’ll see the applicable credit cost before submitting your request.
