Launch Team
Hey Hunters! 👋
Exciting news – React Email 4.0 is here!
We’ve seen incredible growth, with 422,541 weekly downloads (+56% in just 5 months) and 15,509 GitHub stars! A huge shoutout to our 154 amazing contributors who helped make this happen.
Here’s what’s new in React Email 4.0:
🔎 Built-in Linter – Automatically checks all links in your email:
Are they working? (Returns 200 status)
Are they secure? (HTTPS instead of HTTP)
Any broken images?
🚨 Spam Score Checker – Uses SpamAssassin (the #1 open-source spam detection tool) to analyze your email and warn you if it might land in spam.
📩 Compatibility Checker – Checks if your HTML and CSS will display correctly in major email clients like Outlook, Gmail, and Apple Mail. (Powered by Can I Email?)
📱 Responsive Preview – See exactly how your email looks on mobile and desktop. Customize width and height for a perfect fit!
✨ New Components – We’ve added 8 ready-to-use components to make designing emails easier:
Bento Grids
Pricing Tables
Feature Lists
Ratings & more!
We’re super excited about this release and can’t wait for you to try it out! Let us know what you think. 💬👇

@saaswarrior 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.
Getting flagged as spam is always a pain, the spam score feature looks very useful! Great product!

As a developer, this simplifies email design! 👍
It's best to use it with a template and an AI coding tool.
