Is your domains IP address blacklisted?
If you have followed the guidance on reducing the chances of your email going into spam folders but you still have a high percentage of emails that are landing in spam then the first thing you should check is your domains IP address against spam black list databases.
These databases store the IP address of domains that have been known to spam.
Internet service providers (ISP) and email administrators can use this data to block further emails being sent from that domain. In some cases, someone may have used your IP address to send out spam emails, or your emails may have been reported as spam even though they were not.
