See it the way your subscribers will
What looks perfect in the editor can break in Outlook. Preview your modules and emails across 17 real email clients and devices before anything ships.
Built into Better Email — no separate testing subscription required.
Preview across 17 real clients and devices
Every email client renders HTML differently. Better Email renders your email in the clients your subscribers actually use — Outlook on Windows and Mac, Gmail, Apple Mail, Outlook.com, Office 365, Yahoo, iCloud, and real iPhone, iPad, and Android devices — so you catch client-specific rendering bugs before they reach a single subscriber.

Real renderings, not simulations
Your email is rendered in the actual clients your subscribers use, so what you see is what lands in their inbox.
Desktop, web, and mobile
Compare how the same email renders on a Windows desktop, in a browser, and on iPhone and Android devices — side by side.
Catch Outlook quirks early
Spacing shifts, stretched buttons, stacked columns — spot the client-specific bugs that only show up after send.
Test the modules, not every email
Client testing belongs where the rendering risk actually lives: in your modules. Test them once, in the template editor — and every email you build from them is made of markup that has already passed.
Test while you build
Run client previews on a module directly in the template editor, while you develop it. Rendering bugs get found and fixed at the source — once — not rediscovered in every campaign.
Emails inherit tested code
Every email is assembled from your modules, so it only produces markup that has already been through client testing. You don't have to re-test each individual send.
Extra certainty when you want it
We get it — some sends deserve that extra feeling of safety. Client previews are also right there in the Review step of the email workspace, one click before export.
Tested once, at the source.
Every email built from it
Assembled from tested modules — already-tested markup.
Review step · before export
Run client previews on the finished email — optional, one click.
Included, not an add-on
Client testing is usually a separate purchase — teams add dedicated tools like Litmus or Email on Acid alongside their email builder. In Better Email, multi-client previews are part of the platform — in the template editor where modules are built, and in every email’s Review step.
- No separate testing subscription to manage
- No copy-pasting HTML between tools to run a test
- Fix an issue in a module and re-test in seconds — it's the same tool
Your testing workflow
All in Better Email — one tool, one workflow
Rendering is one half. Checks are the other.
Client previews show you how the email looks. Automated pre-flight checks catch what the eye misses — accessibility, broken links, leftover placeholder copy, and more — before anything ships.
Stop guessing how your emails render
See client previews in action — in the template editor while modules are built, and in the Review step before every send.
