Do email campaigns offer attachments like Convert Kit?

I am wanting to switch from MailerLite to an email program like Convert Kit which has the capability of attachments to the emails. I see that SS has an integrated email program but I cannot see if attachments are an option. Please advise :)

I have been using flodesk. Much better for attachments, typography, and well, everything.
