MT Intelligence
Sender Score is a genuine, long-established email deliverability tool operated by Validity (which acquired Return Path in 2019). The domain is 21.5 years old, hosted on Amazon infrastructure with clean antivirus and abuse scores, and is widely referenced in email industry guides. However, the current page returns a 403 Forbidden error, making the live service inaccessible. More significantly, multiple user complaints on Reddit and forums describe the service's blocklisting and delisting process as resembling a pay-to-whitelist scheme, with some users comparing the delisting form to phishing due to excessive personal-information requests. These complaints reflect frustration with the service's practices rather than evidence of fraud, but they do indicate a pattern of aggressive sender reputation management that smaller operators find problematic.
