Styles in custom template get stripped out.

[CharlesM66]

I have created a custom email and defined some css styles in the head section. They preview correctly, but they get stripped out when I send a test email.

Hello @CharlesM66 ,

I reached out to our higher level technical team that handles custom code inquiries, and they're going to take on the case for further review. They should be reaching out to the account's primary email address for an update within the next 4 business days.
