Problem: Cart recovery emails ignore which pricing, layout, or offer variant visitors saw, leading to generic messaging that doesn’t address the friction they actually experienced. Solution: Convert sends experiment and variation exposure into Ontraport as custom data. You segment abandoners by the exact variant they saw and trigger tailored follow-up sequences for each experience. Outcome: Cart recovery flows speak directly to the version users interacted with (e.g., discount vs. no-discount variant), lifting open rates, click-throughs, and recovered revenue while revealing which variants perform best post-visit.
