Run real A/B/C/D/E tests (up to 5 variations) inside HubSpot workflows.
No more downloading contacts, randomizing in spreadsheets, and reuploading lists. Drop our free split-test action into any HubSpot workflow and test anything — content, send time, paths, frequency. Pick the winner when you're ready.
Testing in 4 steps, all native.
Install once. Use in any workflow. No rebuild between tests.
Drop in the action
Inside any HubSpot workflow, you'll find three split-test actions — two-cohort, three-cohort, or five-cohort. Pick the one that matches your variation count.
Add a value-equals branch
Branch on the "cohort" action output. HubSpot auto-creates a branch per cohort. Set up takes 30 seconds — there's no list export, no manual segmentation, no audience math.
Add your variations
Test send times, preview text, subject lines, HTML vs plain, delays, frequency, CTA color, AI on vs off — anything. A "none met" branch protects you against the rare distribution error.
Run as long as you want. Then pick the winner.
No artificial stop conditions. Watch the data, decide when you've seen enough, and update the losing variations to match the winner. The action stays in place for the next test.
The action runs the test. The platform handles everything around it.
The free split-test action lets you set up A/B/C/D/E experiments inside HubSpot workflows. You design the test, you read the results, you pick the winner. That's the point of A/B testing.
The full Seventh Sense platform doesn't replace your tests — it optimizes the variables most teams don't even know to test. Per-person send times. Frequency. Audience recycling. Reputation. The things that move open rates 14-38 points per individual, while you're testing subject line A vs subject line B.
