I can't share the screen shot here, but yes, despite the positive scores, 100% Spam, according to 250ok. We ran a spam test of the same email yesterday and again Outlook did not like it. So it seems isolated to two emails that we have sent, as others have been delivered/opened.
Never mind 250 OK, can you confirm that SCL and BCL are from an email that's in Outlook's spam box?
Well, I looked in MKTO for people with @outlook.com, and found that almost 1,000 opened the email, which means that more received it, which then means the issue most likely lies with 250ok's reporting. Thanks for helping me narrow it down.
"Never mind 250 OK" is a good thing to have in the back of your mind.
Thanks for your help, Sanford, thorough as usual. I'll be keeping that in mind when seeing things in 250ok that aren't reflected in MKTO.
