HTML email is often joked about in how you have to code for it in such an antiquated way (
<table>s! really!) but that's perhaps not a fair shake. 2 years ago Kevin Mandeville talked about how he used CSS grid (not kidding) in an email:
Our Apple Mail audience at Litmus is approximately 30%, so a good portion of our subscriber base is able to see the grid desktop layout.
Where CSS Grid isn't supported (and for device/window widths of less than 850 pixels), we fell back to a one-column layout.
Just like websites, right? They don't have to look the same everywhere, as long as the experience is acceptable everywhere.
Rémi announces the new site:
... we have more than 50 HTML and CSS features tested across 25 emails clients. And we’ve got a lot more coming up in the following weeks and months.
We’re also delighted to present the Email Client Support Scoreboard. For the first time in history, we provide an objective ranking of email clients based on their support for HTML and CSS features.
