I´m in the internet marketing niche and there are certain words that get always caught in the spam filter.I use a thesaurus to find suitable synonyms instead. (I.E. make money online = earn an income on the internet)

That was a very funny spam checker

Take care what spam checker you use. There are some so called spam checkers made by people who don't know what they are talking about.

I remember one of such so called spam checker that was claiming that my name (Adrian), but also Brad and Addison are spam filter triggers Do you know why? Because the "smart" dude who created the checker thought that the word "ad" is penalized. The word "ad" can be found in Adrian, Brad, Addison, etc. so the consequence (in his weird mind) was that all these names are penalized

This is indeed what you really must NOT do. Spammers found this solution long time ago. The brains behind the spam filters acted accordingly
