Hello Product Hunt!
I'm happy to release Stencil, a library that makes HTML email templating straightforward.
Designing and coding responsive HTML templates is trickier than you might expect. Each email client has its limitations and building and testing everything on all devices takes a lot of time.
Stencil tries to solve this problem by providing a set of 4 (onboarding, transactional, newsletter, and code confirmation) starter templates that can be customized to match any look and feel.
Hope you'll find it useful!
