How do you email source code without getting flagged as spam?

Question

When replying to a post (for example on Craiglist) that asks for sample code, is there a way to be (reasonably) sure of delivery?

Here\'s the problem, stated as possible

Answer 1

I don't send code as email. I put my stuff online using Dropbox and send a download link only.

Works perfectly for me and my team.
