Extras Emporium Email Verifier
MailGuard cleans your email lists before you hit send, so you keep bounces low and your sender reputation safe.
Unlike most verifiers, MailGuard never probes recipient mail servers over SMTP. It uses passive checks only: syntax, DNS and MX records, disposable domains, role-based addresses like info@ or support@, and typo detection such as gmial.com to gmail.com. There is zero risk of getting your own IP or domain blacklisted.
Upload a CSV and get three ready-to-import files back: send_safe, risky and invalid. Or plug the REST API into your signup forms to block bad addresses at the source.
Pricing is pay-as-you-go: buy a credit pack once and the credits never expire. Packs start at $29 for 5,000 verifications and go down to $2.80 per 1,000 at volume. New accounts get 100 free credits, no credit card required.
