According to Live Direct Marketing's daily Tranco top-1M scan (July 12, 2026), TOPdesk is the SaaS sender for 449 domains — 0.07% of 617,244 SPF-publishing domains. Detection method: include: mechanisms in the SPF record.
TOPdesk is a Dutch SaaS platform that functions as an IT service management system, sending notifications, escalations, and status updates via email on behalf of customer domains. Organisations authorise TOPdesk to send from their own domain rather than relying on a shared TOPdesk sender address.
TOPdesk's presence in SPF records reveals a long-tail distribution: the platform appears most frequently among mid-market and smaller organisations rather than large enterprises, with particularly dense adoption across the Netherlands and other European regions. When encountered alongside Microsoft 365 (a common pairing), it indicates a hybrid environment where email infrastructure and IT service management are separately managed—a configuration that creates both opportunities and risks for email deliverability, particularly around SPF policy configuration and authentication consistency.

Organisations using TOPdesk typically authorise the platform via an SPF include mechanism, allowing it to send email notifications from the organisation's own domain rather than a third-party sender address. This approach preserves domain branding in email but requires careful SPF configuration and ongoing monitoring of TOPdesk's outbound IP reputation. When SPF records are misconfigured or TOPdesk's infrastructure experiences reputational issues, service management notifications risk landing in spam folders or being rejected entirely. Email administrators should treat ITSM notification flows—particularly automated escalations and critical alerts—with the same rigour as marketing or transactional email, ensuring SPF, DKIM, and DMARC policies align correctly and that the authorised sending infrastructure maintains consistent deliverability.

If your organisation uses TOPdesk, verify that your SPF, DKIM, and DMARC setup correctly accommodates its outbound IP space and treat service management notifications as critical delivery channels. If you encounter TOPdesk in incoming email but do not use it yourself, no action is needed—it simply indicates the sender's domain has authorised TOPdesk for notifications.
