Email Verifier

NeverBounce Bulk Email Verification

Upload a CSV of contacts, preview the expected format, and verify deliverability in real time. Obvious formatting issues are caught before the emails are sent to NeverBounce so you do not spend credits on mistakes.

Expected CSV Layout

Include columns for the contact's name and email on the first row. Accepted headers include Contact Name, Contact_Name, or Name for the name column, and Contact Email, Contact_Email, or Email for the email column. Save the file in UTF-8 CSV format.

Contact NameContact Email
Jane Doejane.doe@example.com
John Smithjohn.smith@example.com
Casey Leecasey.lee@example.com

Tip: export directly from your CRM or spreadsheet with a single sheet to avoid additional headers or merged cells.
