Twitter embeds
Embeds are rich content from other services that bring dynamic flavour to any blog post, and one of the most common embeds that publishers use is content from Twitter. In the browser this has always worked great, but in email clients are a whole different can of worms, and so until now any Tweets shared in an email newsletter would only appear as a basic blockquote. No colours. No fancy styles.
That changes today.
Now, Tweets in newsletters are automatically rendered to look how you would expect; both on the web as well as in email clients.
