More about us →Many online stores leave up to 30% of their revenue potential on the table because they don’t follow up properly when customers signal interest.
A familiar example: customers who bought A also bought B. Everyone knows these recommendations, but few apply them consistently and automatically.
After every purchase, extra carts analyzes whether it makes sense to send your customer a fitting recommendation.
You don’t have to do anything — no flows, no copywriting, and no monthly fee. You only pay once your customers have placed and paid for an extra order — otherwise nothing at all.
Three ingredients, one proven recipe — the full walkthrough takes two minutes to read.
Every recommendation is a short, plain message — like a quick note from your team. No banners, no countdown, one product, with a small image or as a plain text link. You choose the tone and the sender; our AI writes and refines the wording — after every single email.
Proven templates, continuously refined — no builder kit and no mass blasts. The first email goes straight to you, before anything is sent to your customers.
Newsletters are your terrain — that’s where your knowledge of your customers wins. The recommendation after a purchase is a different problem: many dials, and for every one of them a single shop has nothing to compare against. extra carts tests from the first email, compares anonymously across all shops in a category — and the comparison base grows with every new shop.
Shopify Email and the big suites are excellent — if you have the time to run them. But optimizing alone means guessing without comparison, and an agency gets paid whether it works or not. There is only one way extra carts can earn more: your recommendations getting better. And if you start small: on the Free plan, extra carts stays free for good.
Early access starts in Germany — a market with some of the strictest rules for e-mailing customers. That is exactly what extra carts is built for: every check runs before every single send — technically enforced, not just promised. Live today: Germany; the remaining country profiles show where we’re building next.
And yes — these emails are an example of how we want email to be ourselves: short and to the point. We believe a message should always respect the recipient’s time. Neither you nor we have it in abundance.
You write to us, store URL included. An automated confirmation arrives instantly — the only automated mail before a human reads yours. Within 48 hours, Pascal replies personally. No newsletter subscription, no passing your address around.
We check openly whether your store fits yet — from roughly 300 orders in 60 days, German market first. If it doesn't fit yet, we tell you why and when it will. If it fits, you get the installation link and, if you like, a call: you watch your first 30 minutes live.
After a week you get the first results review: what was sent, what it earned, what it would have cost — during early access: nothing. At the end of early access you choose between Free and Fair yourself. No automatic upgrade.
One email is enough — just include your store URL. Pascal replies personally within 48 hours; no newsletter, no passing your address around. Early access is small because a human reviews every install and the first sends. Germany first; other markets join the same waitlist. What it costs you: nothing.
