Help how do i delete email from my galaxy s3?

[skipbrown]

I'm new to the Samsung... having been an EVO fanboy since its inception, but am having an issue that's annoying the hell outta me. I have 2 gmail accts on the phone and when i delete an email, and the phone refreshes, the email comes back. The only way to delete is to log into my email on my pc and delete it from there.

Whazup with that???
