We verify Billions of emails.

An email address is your first line of communication with a customer.

Whether you are trying to send promotions, signup subscribers, generate revenue, generate leads, or grow your business with daily communication, your emails matter.

New prospects providing their email often make mistakes, provide fake emails altogether, or naturally change emails over time. This negatively effects your business in countless ways:

  • Going straight to spam folders
  • Getting banned by your email service provider
  • Being labeled a spammer
  • Losing revenue
  • Frustrating your sales team

Give it a shot. Test an email!
