My website has users buy our products and when the purchase completes, it sends the user an email. However, this email always ends up in spam! When the user first registers, the site also sends an email, this email however is not filtered and goes into the normal inbox. I'm not quite sure why this is so, gmail vaguely tells me that " It's similar to messages that were detected by our spam filters."

So I'm thinking that I need to reword the following email better. Can I get some tips? Or could something else be causing this?

thanks!

here's the unformatted email:
