Revenue experiments
Test the offer. Measure the money.
Turn any segment into a controlled experiment: split customers into treatment variants and a holdout, sync the audiences to Brevo, and track clicks and purchases until you can see exactly what made money.
Deterministic assignment
Customers are bucketed once and never switch variants — no biased results.
A real baseline
The holdout group stays quiet, so you always know what would have happened anyway.
Revenue per variant
Clicks, offer views, checkouts and purchases are attributed to the right experiment.
Incremental revenue
Treatments are compared against the holdout baseline, clearly labeled as an estimate.

Do I need to give SegFuse my Stripe API keys?+
Yes. SegFuse reads your Stripe data to evaluate segments. Keys are stored encrypted, used only to compute segment membership, and never shared or used for anything else.
What happens to my existing Brevo contacts and lists?+
SegFuse creates dedicated “SegFuse:” lists and only adds or removes contacts there. Your existing lists, consent state, and unsubscribe settings are left untouched.
How is this different from Zapier or Make?+
Those are general automation tools. SegFuse continuously re-evaluates who belongs in each segment, so membership updates for refunds, cancellations, and value changes—not just new purchases.
Can I cancel anytime?+
Yes. Subscriptions cancel in one click from the billing page. Your Stripe and Brevo data stays exactly where it is.
How long does setup take?+
About five minutes: connect Stripe, connect Brevo, pick a preset segment. Your first sync runs immediately.
How do revenue experiments work?+
Pick a segment, write a hypothesis, and split the audience into treatment variants plus a holdout group. SegFuse syncs the audiences to Brevo lists, tracks conversion events and revenue per variant, and compares treatments against the holdout to estimate incremental revenue.
Does SegFuse send my campaigns?+
No — SegFuse is not an email editor. It syncs the experiment audiences to Brevo lists (the holdout is excluded) and you send from Brevo as usual. SegFuse tracks the results: clicks, offer views, checkouts, purchases and revenue.
How is incremental revenue calculated?+
The holdout group sets the baseline conversion rate. Expected conversions among a treatment equal that rate times its assignments; incremental revenue is the difference times the tracked or configured conversion value. It is a clear estimate, not a statistical guarantee.
