Hello,
My name is Chander and I work with the Outlook.com Sender Support Team.
I do not see anything offhand with IP: (45.83.106.*) that would be preventing your mail from reaching our customers.
You may be able to find additional information on common delivery questions at the Outlook.com Postmaster Site found at https://mail.live.com/mail/postmaster.aspx I would like to highlight some key areas that I believe are appropriate to your company.
- Outlook.com has created the Smart Network Data Services (SNDS) program. This is a service that helps legitimate email senders work with their customers and partners to reduce spam originating from their IP. To register, please go to http://postmaster.msn.com/snds/ This program allows a sender to monitor the 'health' of their IPs.
- Monitor user complaints. Outlook.com also has a sender complaint feedback loop program called the Junk Email Reporting Program (JMRP). Enrolment in this free program will benefit you as a sender as it will keep your email lists updated and populated with interested Outlook.com customers. This program will help you to remove those Outlook.com customers who do not want to receive emails from your company. If you are interested in joining this program, please visit https://postmaster.live.com/snds/JMRP.aspx?wa=wsignin1.0.
While using the SNDS tool and enrolment in the JMRP will not allow emails from your mail servers to bypass our filters, these are in place to help legitimate companies deliver their emails to Outlook.com customers.
Apply for IP Certification by Return Path, a Validity Product?
If you are doing all the above and you continue to have deliverability issues, you may wish to consider joining Return Path's IP Certified Mail Program, a third-party program administered by Return Path, a Validity Product. Many legitimate mailers and marketers have qualified and joined this program to improve mail deliverability and decrease email from being filtered to the Junk E-mail Folder. Return Path's IP Certification (https://www.validity.com/products/returnpath/certification/) is the only service to which we subscribe
The troubleshooting steps in this email are recommendations only. Microsoft makes no guarantees that following these steps will guarantee deliverability to MSN, Outlook.com, or Live.com customers.
