Abandoned Cart Email Flow: Timing and Sequence

How many emails, how far apart, and what each one is allowed to say. The published data from Klaviyo and Omnisend agrees on the shape more than most marketers expect.

3.33% Klaviyo's benchmark of 143K+ cart flows shows the average brand at a 3.33% placed order rate and $3.65 revenue per recipient, while the top 10% reach 7.69% and $28.89. The practices below are the visible differences between those two groups.
33.00% The economics are honest but modest. In Omnisend's 2026 report data, the lapsed purchase automation averages a 33.00% open rate, 0.52% conversion, and about $0.49 revenue per email against a $94 average order value.
41% Cart flows earn their engineering time. Klaviyo's 2026 benchmark shows automated flows produced roughly 41% of email revenue from just 5.3% of sends.
