Vertical Response has some tips that may or may not set off official spam filters, but they tend to set off human spam filters:

Don’t write subject lines ALL IN CAPS.
Don’t make spelling mistakes.
Don’t plea with people to “Open Me!”
Don’t deceive readers with a false promise.
Don’t give away everything in your subject line.
Don’t use one word – like “Hi!” – as your subject line.
Nix the punctuation.
Don’t add Re: to your subject line to deceive readers.

Luckily, most email marketing services, provide spam checking tools. So be safe- avoid spam trigger words and phrases, spam traps, and always test your email with a spam-checker prior to sending.
