A guide to fixing your email deliverability problem.


Recently, we encountered a problem with our client’s mail server and domain name reputation. Using our technical expertise and knowledge, we worked with our client to resolve the problem. With a bit of research we found their server and IP address had been put on multiple spam blacklists, as a result of their website being hacked and their email accounts being compromised. Thankfully, we fixed their problem and thought we would share our technical advice to anyone who may be experiencing the same or a similar issue – we feel your pain!

To try an eliminate this kind of problem, Windows Live Hotmail have created Smart Network Data Services, a service for anyone with IP space to monitor your Hotmail and Outlook reputation, in an effort to prevent malware, viruses, spam, etc, contributing to a more user-friendly internet. The better your reputation, the better your deliverability. SNDS provides data to help you understand how your reputation is evaluated, and how to improve it. The data allows you to keep your mailing lists clean, as well monitor any IPs you control. A Junk Email Reporting Programme will report when your emails are being put in the ‘Junk’. This service allows users to interact with their client’s data to tackle any problems before they become a larger issue.

In order to gain access to data about the activity of your IPs, you’ll need to prove to SNDS that you are the owner of the IP range.Martin Starkie

In order to gain access to data about the activity of your IPs, you’ll need to prove to SNDS that you are the owner of the IP range. With that, SNDS will provide you with data from log files of the inbound mail machines, as well as other servers at Hotmail and Microsoft. You are then able to act accordingly in order to fix your particular issue, whether that involves increasing your security, replacing or losing a machine, or if you yourself weren’t solely responsible, working with whom was to come to a solution.

SNDS can benefit both your customers and yourself, the service provider, but is also beneficial to the security of the internet in general. Benefits include a much lower cost for network support, deliverability support, and bandwidth; an alternative to port 25 blocking; network protection preventing your reputation being liable for spam, as well as less spam and malicious traffic sent to Hotmail users overall, making for a better user experience; avoidance of users being blocked unnecessarily due to spammers; being more aware of your IP’s data; the ability to more quickly address an issue; and not forgetting, thankful customers for the quality and secure service you are providing.

If you are having trouble with deliverability and it’s urgent, we can help you – please contact us.
