Question

BCL filter in Outlook sending us to spam

Hi all, 

we are using 250ok to test our deliverability, and have discovered that outlook.com sees us as 'not a bulk sender', and sends us straight to spam. 

Code: The message isn't from a bulk sender. (BCL: 0)

Our last two emails were marked 100% spam .

Has anyone worked through this before? 

Thanks!

BCL 0 means you don't send what's considered a bulk amount of identical or near-identical messages to the service. This wouldn't be why you go straight to spam.

You want to look for the SCL and other markers in the SMTP headers. Does DKIM pass for your domain (not just for the marketo.com signature)? Do you have a newly rolled out DMARC record, perchance?

Our 250ok dashboard is giving green ticks for DKIM and DMARC, and SNDS, but yes, it is a new IP address.

Can you show (please highlight using the Syntax Highlighter) the SMTP headers of a message directed to spam? (Or better yet, a couple of messages.)
