Yahoo spam filters

why does my email go to spam in one yahoo account and not the other? I have tested with 4 yahoo accounts and my newsletter gets inboxed to 3 accounts; spam in one. why? this is so aggravating and time consuming. Any insight is helpful. thanks.

Depends on how you trained it and how quickly you sent. Yahoo may be throttling email from your server.

If you have 250ok or litmus you may be able to obtain more insight. You could also post the headers and see if there was any feedback.

Also, check your email addresses in Marketo for Email Suspended Cause and Bounce Reason. The server may have helped.
