See your email the way every inbox sees it.
fold is a no-code email builder with a live cross-client preview: your design rendered on Gmail, Outlook, Apple Mail and more, in light and dark, desktop and mobile, before anyone hits send.
No free plan, but the playground is the real editor, no account needed.
The same email, in the clients that actually matter.
Three of these look right. One does not, and it is the one your reader opens on a work laptop. fold renders all four while you are still editing, so you find out now rather than from a screenshot three weeks later.
fold is in private beta. Leave your email and we'll send an invite as seats open up.
Build it once. Trust it everywhere.
Email clients rewrite your HTML behind your back. fold shows you exactly what survives while you're still editing, not after the campaign went out.
Build without code
Drag blocks, apply your brand theme, and let the builder emit bulletproof email HTML: the table-layout kind you'd never want to write by hand.
Preview light and dark
Every preview renders your email across real client engines in both color schemes, because dark mode is where good emails go to break.
Catch it before you send
Pre-flight checks flag accessibility misses, client compatibility gaps, spam triggers and Outlook quirks, each with a one-click jump back to the block that caused it.
