Class not loaded

Question

I have an CSS style in an external file and the element refers to a the style using the 'class' attribute.

However, I can't seem to get the styling.

Answer 1

Email is notorious for being difficult to style in multiple clients.

For this reason, inline styles and tables are the norm for email templates.

As for loading an external asset, a lot of email clients won't do this for privacy reasons, to prevent the sender from determining if the email has been read by attaching a unique identifier to the URL.

Example

http://example.com/assets/style.css?nonce=ac77f909

The system then checks the nonce against who it maps to, and can tell who is receiving/reading the email.

This is very useful for spammers.
