Need software/site that checks my e-mails for spam keywords

[staffjam]

Hi,

I'm about to send a batch of e-mails out. I've worded them pretty carefully, but i don't want the spam filters to block them.
Does anyone know of a site or service you can use that checks your mails content and hilites words that could get you in trouble?

Thanks for any advice
