Help Scout is a cloud-based customer support platform offering email ticketing, live chat, and help desk features for teams managing customer communications.
Help Scout's presence in email infrastructure is characterised by concentration among smaller organisations rather than enterprise brands—the platform appears predominantly across .com domains and frequently alongside Google Workspace, indicating uptake by small-to-mid-size companies.

SPF and shared infrastructure for support domains
Help Scout's email infrastructure is typically deployed via SPF include mechanisms, meaning organisations using Help Scout add their support domain to the platform's shared IP pool. Because Help Scout's user base is concentrated among smaller organisations and startups rather than enterprise senders, the IP reputation reflects primarily legitimate customer support traffic; however, senders relying on Help Scout share reputation with all other users on the same infrastructure, making it important to monitor bounce and complaint metrics to maintain deliverability.
