The problem
Why most CRM tests never reach an answer
CRM teams are told to test more. The tools they have make it almost impossible. Frequentist statistics, whole-message experiments and siloed results mean most tests end without a verdict, so teams quietly stop running them.
Most tests never reach a conclusion
Traditional tools need a large sample size fixed in advance. For most CRM audiences that means weeks of waiting, and the result still comes back inconclusive. Teams either ignore the maths or stop testing.
Whole-message testing is too coarse
Testing an entire message bundles several creative decisions into one experiment. When the numbers move, you cannot tell which change caused it.
Results do not compound
Each test lives and dies inside one campaign. There is no record of which strategies work over time, and no way to carry a finding across channels.
Metrics miss the business impact
A higher open rate or click rate does not guarantee more revenue. The metric that matters rarely shows up on the report.
How it works
Four steps from content variants to a revenue verdict
No statistics background required. Liftstack runs the experimentation layer on top of the platform you already send from.
Create snippets
Build a library of content variants for any channel: subject lines, hero blocks, CTAs, push titles, SMS copy. Each snippet has a control and one or more variants.
Build your campaign
Connect snippets to slots in your message. Choose the channel, the primary metric and how traffic is split. Group campaigns to coordinate a test across channels.
Assign and send
Liftstack assigns each recipient a variant per slot, writes it to their profile, and generates a conditional template in your platform’s own syntax. Your platform sends as normal.
Read your verdict
Once there is enough data, you get a plain verdict with the revenue impact: winner found, no meaningful difference, or more data needed.
See your potential revenue uplift
Adjust the inputs to match your business. The results show the potential revenue impact of a 15% relative improvement to your campaign conversion rate.
If liftstack improves your conversion rate from 0.10% to 0.12%:
+£3,300 /month
+£39,600 /year
That is 6× your liftstack investment on the Growth plan.

Built for the way CRM teams actually test
Decision-level testing
Optimise individual content decisions instead of whole messages. Test a hero headline, a CTA and a push title at once, without building separate versions of the message.
Multi-channel from day one
Test across email, push, SMS, in-app and content cards. Same statistics, same snippet library, same verdicts. Campaign groups coordinate a test across channels.
Revenue-denominated outcomes
Measure success in incremental revenue, not engagement. Every verdict shows the extra revenue the winning variant earned. That is the number to take to your CEO.
Content memory that compounds
Snippets gather performance data across campaigns and channels. After five campaigns you can see that an urgent tone wins four times out of five in hero blocks for this audience.
