Issue Summary

Failed Add Category on Mail Class (mail.py)

Steps to Reproduce

mail = Mail(m_from, subject, m_to, content)
mail.add_category(event_name)

I think the problem is on code:

 Line 75
        if self.categories is not None:
            mail["categories"] = [category.get() for category in
                                  self.categories]

Sould be:

 Line 75
        if self.categories is not None:
            mail["categories"] = self.categories

Note: I want to make PR on that file but not find the file on this project... Thanks
