The Sender Reputation Data program is a unique email feedback system operated by Microsoft, in which panelists are asked to provide feedback on emails to which they subscribe.
How it works
The Microsoft Sender Reputation Data (SRD) voting system works like this:
- Microsoft invites email users to be part of a program in which they can vote on randomly selected messages as junk or not junk.
- Users have to be actual subscribers of a sender its being asked to vote on.
- Users must also meet other minimum selection criteria, including having an active email account that is at least six months old.
- Users at domains such as Hotmail.com and Outlook.com can accept or decline the invitation to be part of this program. Other Microsoft users cannot volunteer for this program.
- Users are often selected to represent multiple geographies, languages, and types of Microsoft email services, such as Outloook.com, MSN Hotmail, MSN premium, and Windows Live Hotmail.
- If they accept the invitation to be part of the program, they become SRD panelists and periodically receive an email that has a subject line of [Microsoft Spam Fighters] Junk or not?
- Panelists are prompted to vote within 12 to 14 hours after receiving an email that was delivered to them as a subscriber. These voting messages include the original email as well.
- Panelists are asked to classify the message as Not junk email (an email they want) or Junk email (an unwanted email that should not be delivered to their inbox). They are then prompted to confirm their selection.
- Microsoft aggregates the votes and transmits the counts each day to Validity for its Certification program.
- Panelists are added and removed each month to keep opinions objective and to maintain high response levels.
Note: Random samplings of email are extracted and selected to present to panelists prior to having any anti-spam technology applied during the delivery process. This allows for responses to be obtained for email regardless of whether it was delivered or where it was placed, such as in the inbox or in a junk folder.
