The problem

You have one clean mailing list and need two equal buckets for subject-line or creative tests.

Steps

  1. Remove duplicates first.
  2. Optional: shuffle with Random mode for random assignment.
  3. Open List Splitter → Into K groups → K=2.
  4. Copy Group 1 and Group 2 into separate campaigns.

For fixed batch sizes (e.g. 500/day), use Split List into Chunks with N=500.

Frequently Asked Questions

Are the groups randomly shuffled?

No — order is preserved while distributing into K groups. Shuffle first with Text Sorter random mode if you need a random assignment.
