Helping email marketers communicate better in the attention economy

Inbox Maestro is the email intelligence assistant built by Viaretina — a French company specialized in visual experience, cognitive science and conversion performance. We help Email Marketers and CRM teams understand what their campaigns communicate, how they're perceived, and how to improve every email before sending.

Grounded in research

We do the digging, so the advice you get holds up.

Founded in 2021, Viaretina grew up inside some of Europe's more demanding innovation programs, and we still spend real time in research.
Not for the badges — but because useful advice needs to rest on something more solid than an opinion.

What we care about

A few principles we don't compromise on.

Responsibility

We help teams understand how human attention really works, to make the experience better for the reader. And we turn down any request that runs against our ethics.

Honesty and Transparency

We're upfront about what AI and cognitive science can do — and just as honest about where they stop. No hype, no promises we can't keep.

Simplicity

Expertise only helps if it's easy to understand. So we work hard to turn complex analysis into clear, practical decisions you can make in minutes.
