Congrats on launching React Email 4.0! The built-in linter, spam score checker, and compatibility tools are huge for email devs. Responsive previews + new components make it even better. Excited to try it out! 🔥📩
this is really great stuff! i wish we had these tools integrated before, would save so much time. makes building the emails much less painful now. the linter and spam score directly in workflow? genius. feels way smarter than juggling separate checkers and praying lol. this will definitely help us make sure our user emails actually get delivered and look right everywhere, which is always a fight. those new components look handy too (⌒▽⌒) congrats on launch team! great work.
In a world where AI is automating 90% of your feature list, what does your roadmap look like?
Getting flagged as spam is always a pain, the spam score feature looks very useful! Great product!
