Our Process

Our 20-step process utilizes a complex set of algorithms to test and repair each bad email address independently. Here's a high-level view of our proprietary process:


  • Verify Email - jsmith@abc.com is valid; j~sm!th@abc,com is not
  • Verify DNS – Will the domain accept this email?
  • Flag – Identify all spam traps and "honeypots"
  • Test – We ping all remaining emails to ensure deliverability
  • Repair – When appropriate, we will repair improperly formatted email addresses
