Can I A/B test email timers?

I'm looking to optimize my email marketing campaigns and want to understand how to effectively A/B test countdown timers in my promotional emails. I've heard these timers can create urgency and improve conversion rates, but I'm unsure about the best practices for testing, what metrics to track, and how to implement them strategically. I want to ensure I'm not just adding a timer, but actually improving my email performance and driving more sales through data-driven experimentation.

The short answer

Exit-intent discounts should be 10-15% for most products - enough to overcome price hesitation without training customers to always wait for the popup. For high-margin or high-AOV products, a fixed amount ($10-$20 off) can feel more compelling than percentage off.

In depth

What Discount Should Exit-Intent Show?

Exit-intent discount sizing requires balancing conversion effectiveness against margin protection. The right discount is the minimum needed to tip the undecided visitor into purchasing - not the maximum you're willing to give.

Growth Suite Margin Protection

Growth Suite's Purchase Intent Prediction identifies which visitors are walk-away customers (need the nudge) vs. dedicated buyers (would purchase anyway). Exit-intent discounts are shown only to the former, protecting margins by avoiding unnecessary discounts to visitors who would have converted regardless.
