Sparkpost emails going straight to Junk Mail (o365)

[sudo]

Hi

It seems you may have switched from Mandrill to Sparkpost in the last 24 hours, now every email I get is going to Junk Email on o365 with a spam confidence level of 9.

Are you using a dedicated ip or just the pool Sparkpost use?

I can send the headers through if that would help. I personally found the exact same problem when I was testing SendGrid and its dedicated ip.

If the from address is from your domain do you have proper spf records setup? Microsoft is picky like that!

Mines also go to the spam folder and I have everything set up and verified :/

SPF record, DKIM record, and the email.

What are the email headers when the email has been delivered? Specifically, what's the Authentication-Results header?

I had the same problem and contacted support, they were able to get everything working for me again. I believe it was on their end, not mine.

Just to add it appears IPB are not using a dedicated ip which seems to explain why 25-50% of mail sent is getting junked on o356/outlook.com/hotmail.com email addresses went it comes from one of the *general* ip's.

Its not a problem with my own site, its this sites emails which is why I posted it in company feedback rather than product feedback.
