What You'll Get — Free

  • Duplicate report — exact duplicates, same-household entries, and name-variation matches, merged the way a mail house would.
  • Valid record count — how many real, reachable households are in your list.
  • Campaign estimate — what a multi-wave SimplyIOP campaign would cost for a list your size, and the offertory increase churches like yours typically see.

Why De-Dup First?

Most church lists carry 2–5% duplicate households — "John & Mary Smith" and "Smith, John" at the same address. Every duplicate is a wasted printed piece and a family asked twice. We merge them before anything is estimated or mailed.
