What SendBridge is

SendBridge checks whether addresses are real before you mail them. It validates mailboxes, cleans lists, and inspects SPF, DNS and MX records so a sending domain is configured properly.

An API is available so verification can run inside your own process.

What you can do with it

  • Verify email addresses before sending
  • Clean a stale mailing list
  • Check SPF, DNS and MX configuration
  • Run verification through the API
  • Reduce bounce rates and protect reputation

Who it is for

  • Email marketing teams
  • Sales operations running outbound lists
  • Agencies cleaning client lists
  • Businesses recovering from delivery problems

What to watch out for

  • Verification does not make an unconsented list lawful to mail
  • Consent, unsubscribe and privacy rules still apply
  • Catch-all domains cannot be verified reliably
  • Configuration checks do not fix content or list quality
