According to Live Direct Marketing's daily Tranco top-1M scan (July 12, 2026), SuperOffice is the SaaS sender for 99 domains — 0.02% of 617,244 SPF-publishing domains. Detection method: include: mechanisms in the SPF record.
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.

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.

If SuperOffice shares the SPF record with many other services, the domain is at risk of hitting the DNS lookup limit, which may silently break authentication.
