That may be the case at the more sophisticated ISPs (gmail, yahoo, etc.) but I think it's still worth consideration. There are a lot of old school email servers and spam filters out there. I would suggest using tools like litmus and others because the "stop words" are not always intuitive.

I see, thanks for the quick reply. Currently using Email on Acid for verifications and testing, maybe will move onto Litmus at a later stage. Thanks!
