One platform to manage every client and campaign
Running email production for five clients at once? RGE Studio brings creation, client brands, approvals, reusable assets, and exports into one place, so your team can move faster without losing track of what belongs to whom.
Why agencies need an email builder built for client work
Different approval chains. Different sending platforms. Different definitions of “on-brand.” Sometimes all at once and even before lunch.
Most email tools are built around one brand, one team, and one workflow. RGE Studio is built for multi-customer agency reality.

Multi-client complexity
Keep each client’s brand, assets, and work in its own workspace, so the wrong logo doesn’t sneak into a Friday-afternoon send.

Faster approvals
Move feedback into one place that clients and your team can actually follow.

Reusable, brand-safe production
Save the pieces that work and reuse them without rebuilding every campaign from scratch.
Discover what fellow agencies are saying
Navigate multiple clients, projects, and campaigns with ease
Set up each client’s workspace, brand assets, and guidelines once. Then give your team a clear place to build, review, and organize the work.

Keep every client’s brand consistent
Give each workspace its own colors, fonts, assets, and guidelines. Your team has the right brand ingredients in front of them while they build, instead of relying on memory and crossed fingers.
Work with whatever your clients already use
Your clients probably aren’t all using the same ESP or MAP. That’s fine. Connect with supported platforms or export clean HTML and move it wherever the campaign needs to go.
Build once, reuse across clients and campaigns
That great module you built three months ago is still great. Assuming anyone can find it.
RGE Studio turns your best work into reusable building blocks. Save templates and modules, bring them into future campaigns, and spend less time staring at an empty canvas wondering why you didn’t save that thing from last time.

Reusable modules
Save headers, footers, CTAs, and other repeatable sections for future campaigns.

Editable templates
Turn successful designs into templates your team can use again and again.

HTML import
Bring existing email HTML into RGE Studio and continue working from what your client already has.
From brief to export, with AI
Blank pages and busywork eat billable hours.
With the RGE Studio MCP, connect your AI tool of choice and you can pull up client emails, spin up new versions, save them to the right workspace and export the HTML. Inside Studio, AI Co-Pilot turns rough briefs into drafts.
Handy for one client. Even better for six.

Scale your team’s email production
Getting one email out the door shouldn’t require five tools, three tabs, and a Slack archaeology expedition. RGE Studio brings creation, organization, and review into one workflow that can keep up as your client list grows.
Set access by role
Give team members and collaborators the access they need while keeping client work and brand assets where they belong.
Move fast without starting from scratch
Brand assets, modules, and templates are already waiting for you: assemble what works, customize what matters, and keep moving.
Keep client reviews, feedback, and approvals moving
Client feedback shouldn’t live across six Slack messages, two PDFs, and an email that starts with “one last thing.”

Reviewer-only access
Clients can comment, approve, or request changes without editing the design itself.

Comments tied to specific elements
Feedback stays connected to the work, so your team spends less time piecing together what changed and who asked for it.

Approval records and PDF exports
Keep a record of every approval, and export PDFs for clients who still enjoy getting out the digital red pen.
Built to work with your clients’ existing tech stack
Different clients use different sending platforms. Agencies call that a Tuesday.
RGE Studio works with supported ESPs and MAPs and gives you the option to export clean HTML when you need more flexibility. Your clients can keep the tools they already use. You can keep your production process moving.

Frequently asked questions
What makes an email creation platform useful for agencies?
Agencies need more than a place to design an email. They need to manage multiple brands, reuse proven assets, collect client feedback, and keep production moving across several accounts at once. The right platform makes client number six manageable without turning your workflow into spaghetti.
Can RGE Studio support multiple clients or brands?
Yes. You can organize client work into separate workspaces with their own brand assets, guidelines, and permissions, making it easier for your team to move between accounts without mixing things up.
Can clients review emails without editing them directly?
Yes. Reviewer access lets clients leave comments and provide feedback without editing the design itself. Comments can stay tied to the relevant parts of the email, and PDF exports are available when offline review makes more sense.
Does RGE Studio work with the sending platforms our clients already use?
RGE Studio supports integrations with popular ESPs and MAPs. When a direct integration isn’t available, you can export your email HTML and move it into your client’s sending platform.
