Maximising Email Deliverability with Salesforce Marketing Cloud – ISP Feedback Loops



  In the dynamic world of digital marketing, understanding and managing ISP Feedback Loops is crucial for the success of email marketing campaigns. This becomes particularly important for Salesforce Marketing Cloud users as these feedback mechanisms are integrated into the platform, offering a unique advantage in managing email deliverability and recipient engagement.


Understanding ISP Feedback Loops in Email Marketing

ISP Feedback Loops allow recipients to report unwanted emails as spam. This feedback is essential for email marketers, as it helps maintain a healthy sender reputation and ensures compliance with anti-spam laws. When a recipient clicks the “report spam” or “this is spam” button, an FBL complaint is generated and returned to the Salesforce Marketing Cloud.


The Role of Salesforce Marketing Cloud in Managing Feedback Loops

Salesforce Marketing Cloud simplifies the process of managing ISP Feedback Loops by automatically enrolling its clients in various ISP feedback loops. This feature is critical for marketers as it saves time and ensures comprehensive coverage. The ISPs included in this automatic registration are:

  • Bluetie (Excite)
  • Comcast
  • Cox
  • Fastmail
  • Microsoft Hotmail
  • and many others.

This automatic enrollment means no additional action is required from the clients’ side to participate in these feedback loops.


Special Considerations: Yahoo! Mail and Gmail Feedback Loops

It’s important to note that Yahoo! Mail and Gmail operate their feedback loops differently:

  • Yahoo! Mail: Clients are not automatically enrolled in the Yahoo Feedback Loop. Specific steps must be taken to register your domain for this feedback loop.

         Register your Marketing Cloud domain for the Yahoo Feedback Loop article for more details.

  • Gmail: The Gmail Feedback Loop does not function as a standard Feedback Loop. Understanding its unique operation is crucial for effective email marketing with Gmail users. Clients need to enroll in Google Postmaster Tools.

Best Practices for Leveraging ISP Feedback Loops

  • Monitor and Analyze Feedback: Regularly review the feedback from these loops to understand recipient preferences and improve email content.
  • Maintain Email List Hygiene: Use the feedback to keep your email list clean, removing recipients who consistently mark your emails as spam.
  • Compliance and Reputation Management: Adhere to anti-spam regulations and maintain a positive sender reputation by responding appropriately to feedback loop data.
  • Tailor Strategies for Different ISPs: Recognize the differences in how various ISPs handle feedback loops, especially in the case of Gmail and Yahoo! Mail, and adjust your strategies accordingly.


Integrating ISP Feedback Loops into your email marketing strategies offers a streamlined approach to managing recipient feedback. 

By understanding how these systems work and utilising the automatic enrollment feature, marketers can enhance email deliverability, maintain a positive sender reputation, and ensure their campaigns are more recipient-friendly. 

Special attention to platforms like Yahoo! Mail and Gmail will further refine your strategy, making your email marketing efforts more effective and compliant.
