Handling SNDS requests

I’ve been working with a new client on getting them signed up for FBLs, whitelists and other sorts of monitoring. One of the places I recommended to them was signing up for the Hotmail Smart Network Data Services (SNDS) program. It’s been a while since I’ve gone through the process, so I decided to sign up our network space to give up to date instructions from to clients.

They use public records (ARIN and IP Whois data) to figure out the “network owner” and send an email to that person. In my case, the mail was sent to a role account at Hurricane Electric (
I asked for access, filling in “this is Laura from Word to the Wise and I am looking for access to our space.” The email address in the request was my address. A few minutes later I checked my inbox to find an email from

We have generally been happy as a customer of, but was impressed they have systems in place for handling SNDS requests. I know this was a boilerplate email, but it was a well done boiler plate. It had the information I needed to confirm the request, let me know what to do if there was abuse, and was sent out within an hour of the signup.
Low volume, highly personalized transactional email is something we don’t often talk about as senders. But this type of email is very important.
