What is EmailVerify?
BillionVerify is an email verification service that checks addresses before they enter your lead lists, signup flows, or outbound campaigns. It combines syntax, domain, MX, SMTP, reputation, and risk checks, then returns clear statuses for individual addresses, lists, and API workflows. The goal is to help you reduce bounces and improve sender reputation.
You can verify a single email in real time, upload CSV files for bulk cleaning with live progress, or use the API to verify addresses during signup or in AI agent workflows. Results show SMTP verification, MX records, and a deliverability score. The bulk tool gives you validity distribution, status counts, and export filters so you can remove bad addresses before sending.
BillionVerify suits marketing, sales, e-commerce, and agency teams. It integrates with tools like Mailchimp, HubSpot, Salesforce, Zapier, and Make. The site offers 20 free credits a day, up to 600 a month. It also provides a whitelabel service to launch your own branded verification portal.
