Email testing shouldn't be a luxury.
For years, checking how your email actually renders meant one of two things: pay hundreds of dollars a month for enterprise QA tooling, or send it and hope. Then the affordable tiers disappeared entirely. The tools that served freelancers and small studios moved upmarket and left them behind.
fold is the answer to that gap: a visual builder and a true cross-client preview grid (light and dark, desktop and mobile, real classic Outlook included), priced for the people doing the actual work.
What we believe
Three principles shape every decision in the product, from what we build to what we charge for.
Honesty over hand-waving
Every preview tile tells you exactly what it is: which parts are the real client engine and which are its documented behavior applied. If we can't say what something will look like with confidence, we say that instead of guessing.
Never meter the loop
Tweak, re-check, tweak again. That loop is the whole job, so it's unlimited on every plan. We only meter the one thing that costs real money to run, and we're transparent about why.
Priced for independents
Freelancers, solo marketers and small studios were priced out of email QA. fold starts where the enterprise tools stopped caring: no contract, no sales call, and no free-tier bait either. It's a paid tool that earns it.
See it for yourself.
The playground is the real editor and the real preview grid, no account required. That's the pitch: the product is the demo.
