Cart recovery tools price three ways: per message, as a share of recovered (or total) revenue, or flat per month. The first two have a property worth noticing: the better the tool works for you, the more you pay — your success raises your bill.
Why usage pricing exists
It's not malice; it's channel economics. Tools built around SMS pay carriers for every message, in every country, plus compliance overhead — which pushes them toward usage-based or revenue-share pricing. Some recovery tools price as a percentage of the revenue they touch for the same reason.
What changes with email + web push
Email and web push generally have far lower variable delivery costs than SMS. A recovery tool built on those two channels can offer a flat monthly price that stays sustainable for the vendor and predictable for you: your November (peak season, most abandoned carts, most recoveries) costs the same as your February.
The math that matters
Suppose you recover $2,000/month. At a 10% revenue share, that would be $200/month — every month, growing with you. At a flat $19–59, the fee is the same whether you recover $2,000 or $20,000. The difference compounds exactly when your store takes off.
Our version of this
Cartback is flat: a free plan (50 reminders/month — genuinely usable for a small store), then $19 or $59 flat with a 14-day trial. No percentage, no per-message fees, no surprise seasonal bill. You keep 100% of what you recover — which is the whole point of recovering it.
