Request: break up options.preserveStyles into separate options

[albell]

Nowadays, for design-sensitive work, <style> elements in email are typically required, because they are needed to target elements that are created dynamically by certain email clients, e.g. the nested anchors iOS creates on addresses.

So, for example, it would be nice to have a way to allow preserve <style> tags while still inlining the contents from <link> tags.

I would like to suggest segmenting options.preserveStyles into options.preserveStyleEl and options.preserveLinkEl. It would be nice to have more granular control.

Thanks for a great tool.
