Outlook 2013 tests my newsletter with a few tests, and gives the newsletter a Spam-Score of 3.9 (5 is required). I wan't to have the score as low as possible, but I can't find what to do at the "HTML_TITLE_SUBJ_DIFF"-Test, and nowhere is written what's that for a test is.
Do you have some experience with that?
Thanks in advance. Regards, john
