Why DocuSign appears in this category
DocuSign is currently catalogued from its observed DNS role.
We classify it as a uncatalogued service from include: mechanisms in the SPF record matching a maintained provider rule. This is infrastructure attribution from public DNS, not evidence of a direct contract or exclusive use.
DocuSign is a software-as-a-service platform for electronic signatures and document management that sends email on behalf of customer domains. It handles outbound delivery of signing requests, completed documents, and related notifications to end recipients across the internet.
DocuSign's mail infrastructure footprint is concentrated amongst smaller and mid-market organisations rather than the largest enterprises, with a marked presence in the .com domain space. It commonly appears in SPF records alongside Microsoft 365, a combination that signals a particular organisational technology profile centred on integrated contract workflows and customer communications.

SPF Record Complexity When Authorising DocuSign Senders
Adding DocuSign to an SPF record authorises their servers to send email on your behalf. The combination of DocuSign with Microsoft 365 and other vendors often approaches or exceeds the limit of DNS lookups permitted in SPF validation, causing authentication failures that manifest as deliverability problems for DocuSign-generated messages despite the service being legitimate and properly configured.
