Deliverability issues in Hotmail/Outlook
We have recently started up our email marketing business and have a problem.
After an IP warm.up, we can deliver to the inbox our offers to our customers in Yahoo easily, but Hotmail/Outlook still resists.
We have IP addresses with 100% reputation scored by ReturnPath and have a good and realible content (the same mail says: Spam Content Level=0), but emails go to the junk anyway.
So, if we have good IPs and no spam messages, what else do we need to make inbox in Hotmail?
Any help will be truly appreciated.
