Built for what comes next

Transactional email deserves more than an afterthought

Transactional email gets opened more than almost anything else you send, yet it’s usually the last thing your team polishes. RGE Studio gives you a real design layer to fix that, and once it’s built, it’s ready to go out through ZeptoMail.

Built to look like your brand, not a template

No HTML needed. Adjust text, colors, fonts, and layouts, drop in images, video, polls, or GIFs, and build in minutes what used to take hours of hand-coding.

Comments, not comment chains

Draft and give feedback together, right on the design. Tag teammates on specific elements so they get notified, assign roles on paid plans, and move through approvals without a single screenshot or email thread.

Looks right, no matter the screen

Start from a prompt, not a blank canvas

AI Co-Pilot lives right inside the builder, so you can draft a campaign, rewrite existing copy, or tweak a design with a prompt, no switching tools. Already using another AI tool? Plug it in through RGE Studio MCP instead.

Send it through the connector, or export the HTML and bring it in yourself. Mix and match, switch tomorrow, there's no wrong way to do it.
