Flatmail for Shopify · launching January
Early access · limited first cohort

Your emails made you less than your email app says.

Klaviyo, Mailchimp and Omnisend count a sale as "email revenue" off an auto-open days earlier — and leave refunds in. Flatmail counts it only when someone clicked and bought within 24 hours, refunds off the top. The number you see is the number you made.

Built by one founder, in the open. No VC, no per-contact billing, no fake metrics.

Illustrative figures, to show the method. Every honest email tool should land on the lower number — somehow we're the only one that does.

The number isn't a lie, exactly. It's just counted three ways that quietly push it up.

How a "£1,847 from email" figure gets built — some of it's in their own docs.

01 · The phantom open

Apple opens your email for you.

Apple Mail pre-loads the tracking pixel on every message, logging an "open" whether anyone read it or not — on a majority of most lists. Klaviyo's own docs admit it "artificially inflates your open rates."

02 · The open counts as a sale

A phantom open earns the credit.

The default model credits email for a purchase if someone opened or clicked within a multi-day window. A sale that'd have happened anyway gets tagged "email revenue" off an open that was never real.

03 · The refund never leaves

Returned orders stay in the total.

When a customer refunds, the money's gone from your bank — but it stays sitting inside the "email made you £X" figure. What you're shown is gross, and quietly out of date.

Flatmail removes all three. No opens counted. Revenue only on a click-then-buy within 24 hours. Refunds subtracted as they happen. What's left is just… what you made.

We built the email tool we wanted as merchants — one that never lies to make itself look good.

No open tracking. At all.

Pixels and Apple inflate open rates, so we don't have them — not hidden in a menu, nowhere. Only clicks and sales, because those are real.

Them: revenue built on opens that were never real

Pay for sends, never for contacts.

Billing is based on emails actually delivered — never on the size of a list you're punished for growing. Flat pricing you can predict to the penny.

Them: billed by contact count, even people who never opted in

We watch every send for you.

If a send breaks, billing stops and you hear it from us first. Locked verified sender, an unsubscribe footer that can't be removed, real numbers or nothing.

Them: you find out from an angry customer
