Overview
Your client reads email in an inbox, so that’s where Honter shows it. Each design opens in a familiar mail frame with its subject and preheader, one tab per email.
Review the email the way it will be opened
An email design pasted into a slide hides the parts that decide whether anyone opens it. Honter shows each design inside a mail-style frame, with the sender, the subject line and the preheader where the reader will see them. Sending a welcome series or a cart recovery flow? Every email gets its own tab, and an overview shows them all at once.
Subject lines your client can choose
When you set up the project, Honter can suggest a subject line and preheader from your designs. Your client gets a sparkle next to the subject that offers three subject lines and three preheaders at sensible lengths. They pick one, tweak it or write their own, and everyone sees it live.
AI reviewers that read the copy
In email, the copy is the email. The Translator leads here, flagging lines that will read differently than you meant. The Skeptic and the Audience check whether the message holds up and whether a reader would act on it. The subject, preheader and sender are part of what they read.
Design review, not inbox testing
Honter reviews the visual design of an email. It doesn’t render HTML or test how the email looks across mail apps, so pair it with your email platform’s testing tools before you send.
Best for
Agencies, lifecycle teams and freelancers designing campaigns, newsletters and automated flows.
