Using quotation marks, dollar signs and exclamation points in subject lines frequently trigger mail filters, as well as using all capital letters (shouting). Avoid toll-free numbers in the subject line, because that also causes your email to be filtered out by many spam filters. And never use a font size larger than 2+, or you could trigger some Spam filters.
