Do you avoid using words that make your email like junk mail?Last updated by Brady Stroud [SSW] almost 3 years ago.See history
Outlook by default reads your emails and can flag your email as potential junk email, or adult content email by examining a list of Sensitive words. This list is not available to the public.
You should avoid any swear words or be using an angry tone as well.
We have a program called SSW LookOut! for Outlook to check for this rule. Figure: SSW LookOut! for Outlook checks that you don't use bad words.
