Hi
Thanks for getting in touch.
Are you able to provide the full headers of an email that was delivered to the junk folder of a recipient?
Info on how to obtain the message headers can be found here:
https://mxtoolbox.com/Public/Content/EmailHeaders/
Note that the headers will have to come from the recipient mailbox and not the sent folder of the sender.
Email headers often contain the results of tests that mail servers perform against the sending server or email address/domain which may help in identifying why the message was sent to junk.
We look forward to hearing from you.
