get_results

MCP tool · email experiment metrics

get_results returns per-variant open and click counts, the winning subject line for the experiment, and within_test_lift — the relative improvement of the winner over the other variants in the same send. Use this after a launch_test has had time to collect engagement.

When to use it

Example

{ "experiment_id": "exp_..." }

Methodology note

Compare variants within the same experiment only. Pool within_test_lift across experiments later — do not compare absolute open rates across different lists or cohorts.

Next step

Call recommend_next for a suggested follow-up test dimension.
