Categories should be a property on the mail object (not included in the headers) as per the docs here: https://sendgrid.com/docs/API_Reference/Web_API_v3/Mail/index.html
So to use in this library, you would need to do something like this
msg = EmailMessage(...)
msg.categories = ['dev`]
How do I add categories to the email?
I tried something like this but no dice.
Any thoughts?
