See what your email should really be making you.

1. Flows. Each flow is sized off Klaviyo's published revenue per recipient: a welcome flow makes about $2.65 per new subscriber, an abandoned cart about $3.65, and so on down the list. A flow you do not run counts its full benchmark; a flow you run counts only the gap to a well-built version. Flows fire mostly on new people, so your list size does not change the ongoing flow number.
2. One-time list blast. When the never-bought, second-order and winback flows first turn on, they email everyone already on your list who qualifies, one time. Kept separate, never shown as if it repeats.
3. Broadcasts (monthly service). Klaviyo's data shows campaigns are about half of a store's email revenue, and email is 20 to 40% of total revenue for a well-run brand. So a well-run campaign program is about 10 to 16% of your store revenue. We take the gap between that and what your campaigns make now. Five sends a week is the frequency the largest studies show subscribers tolerate before it backfires.
4. We do not count every dollar. Some sales would have happened anyway, so the numbers stay at the conservative end. You pay on the lift measured inside your own Klaviyo against a small holdout group, not on this estimate.
