Why SuperOffice appears in this category
SuperOffice — Scandinavian CRM.
We classify it as a SaaS sender 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.
SuperOffice is a cloud-based customer relationship management platform operated by SuperOffice AS, a Norwegian software company. It provides email sending services for marketing, sales automation, and customer communications, with customers authorising its infrastructure through SPF records.
SuperOffice's sending footprint sits predominantly among smaller and mid-market organisations rather than the largest global brands. Its presence correlates strongly with Microsoft 365 deployments, reflecting the typical scenario where organisations layer SuperOffice's CRM capabilities atop Microsoft's email infrastructure. For email administrators and deliverability teams, detecting SuperOffice in SPF records indicates reliance on managed third-party email services—an architectural choice that carries implications for authentication configuration and delivery predictability.

SPF configuration and the DNS lookup limit
SuperOffice's SPF mechanisms require authorised include statements in customer SPF records, and when combined with Microsoft 365, Salesforce, or other SaaS platforms, the cumulative DNS lookups can quickly approach or exceed the hard limit of ten lookups per record. Organisations with multiple email service providers must carefully audit their SPF syntax to avoid exceeding this ceiling, which causes authentication failure regardless of whether individual senders are legitimate. Flattening, consolidating, or transitioning to DKIM + DMARC-focused authentication becomes necessary at scale.
