What it does

  1. Removes current customers, open deals and opt-outs
  2. Removes duplicates and people who left the company
  3. Checks what is left for missing emails and wrong titles
  4. Returns a go, fix or stop verdict with the rows it kept

You give it

  • The list or audience to check

You get

  • A go, fix or stop verdict
  • The clean list
  • The reason each row was dropped

Why it works

A bad list costs more than a bad message: bounces, angry customers and burned domains. Checking first protects every campaign after it.
