Has anyone done responsive email marketing, I found several models on the internet they work responsive in the browser but when I fire the email via Outlook or virtual target and open it on my cell phone (Gmail application) the email is not responsive someone has already passed that's why?
I use a tool called MJML for assembling templates. It has its own code and is quite complete. In the end it gives us a specific html code for responsive emails.
Here you will find some examples of templates made with the tool.
And here's even a playground for you to test your code.
This tool also has a
VSCODE extension similar to the playground, where you go coding and have the preview on the side.
