Email Address Verification

Verifying an email address means checking if it’s valid, active, and able to receive mail without actually sending a message. This helps reduce bounces, avoid spam traps, and protect your sender reputation.

The 3 main methods:

  • Syntax check: Does the email follow a valid format (no typos like “gmial.com”, missing @ symbol, etc.)?
  • Domain check: Is the domain (like gmail.com) live and configured to accept mail?
  • Mailbox ping: A non-intrusive server check to see if the specific email inbox exists.
