Hi Product Hunt 👋 I kept running into the same wall: email HTML is basically a separate craft. Outlook needs VML for buttons, Gmail clips anything over 102KB, and a layout that looks perfect in a browser falls apart in half the inboxes. So every time we needed a campaign, it went through three people — a designer drew it, a developer coded it, a marketer filled it in. Days of work for one email. Mailvex takes that path down to one person. You assemble the email from blocks, upload your brand book as a PDF and it pulls out colours, fonts and logo automatically. The compiler handles the ugly parts: VML fallbacks, inline styles, table layout, weight under the clipping limit. What comes out is clean HTML that pastes into any sending platform. 160 templates across 10 industries, four interface languages, free plan with no time limit. I'd genuinely like to hear where it breaks. If you build emails regularly, tell me what your current process looks like — I'm still learning where the real pain is.
