Today, we have an open-source launch for you. Announcing React Email 4.0. 1. Built-in Linter 2. Spam Score 3. Compatibility Checker 4. Responsive Preview 5. New Components

First of all, I just wanted to say thanks. React Email now has 422,541 weekly downloads on npm, that is a 56% increase since the last major release 5 months ago. We also have 15,509 stars on GitHub and would like to thank all the 154 contributors who made this possible.

1️⃣ Built-in Linter The new Linter tool will analyze every link in your email to see if it's valid or not. • If the links are valid and returning a `200` response status • If the links are secure and using `HTTPS` instead of `HTTP` It will also check for broken images.

2️⃣ Spam Score The Spam Score will look at your email content and use a robust scoring framework to determine if the email is likely to be spam. It's powered by SpamAssassin, the #1 open source anti-spam platform.

3️⃣ Compatibility Checker The new Compatibility Checker will see how well the HTML/CSS is supported across popular mail clients like Outlook, Apple Mail, and more. It's powered by Can I Email, an open source repository of features and their compatibility for each email client.

4️⃣ Responsive Preview React Email now comes with a Responsive Preview, so you can see how your email will look like on different device sizes. There are presets for mobile and desktop, and you can also customize the width/height of the preview.

5️⃣ New Components We've added 8 new components that you can copy-and-paste into your emails. They include Bento Grids, Pricing Tables, Feature Lists, Ratings, and more. • • •
