The honest answers.

  • No guaranteed return. We supply targeting, you run the campaign.
  • No word-of-mouth percentage, because there is no honest one.
  • What happens to your data. Emails hashed, addresses encrypted, contacts never leave.
  • What we do when the signal is not there. We tell you, plainly.

See it on your own data.

Read the method, then bring us your next campaign. We point it at your growth and measure the lift.
