Gmail ignores @media query blocks that contain class names with ":" or "@" about bojler

Hi @dcpedit, we are already aware of this issue and we will remove classes with "@" and ":" suffixes in v5.0.0. Right now we need to leave them available because of backward compatibility issues that might occur if we remove them.

That is already noted in our documentation, for example: https://take.ms/mGj6T

Thanks!

This will be released in v5 soon.
