Talk to a real human.

Every email lands with the people who build SmartSize — no ticket maze, no chatbot pretending to be a person. Just write to us:

We reply fast — usually the same day, on European time.

The inbox is the best part of this job.

SmartSize is built by a small team that started out where you are now — running stores, agonising over returns, and answering “will this fit?” one message at a time. We built the app we wished we’d had back then. The part we never expected to love this much is hearing from the people who use it.

So write to us the way you’d write to a colleague. A rough idea, a half-formed question, a screenshot of something that looks slightly off — all of it is welcome. A real person reads every email, and that person can usually fix things the same day, because they built them.

Rather talk it through?

Say the word and we’ll send over a call link. We’re genuinely happy to jump on a call — merchants, agencies, partners, anyone.

Bonjour, hallo, ciao, olá, hola.

The team speaks English, French, German, Italian, Portuguese and Spanish — and if you’re already using SmartSize, the in-app chat answers in any language you like.
