Why ServiceNow appears in this category
ServiceNow — ITSM enterprise platform.
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.
ServiceNow is a cloud platform operated by ServiceNow Inc. that enables organisations to automate business processes and service delivery. A core feature is its ability to send transactional and notification emails on behalf of customer organisations, integrating with their domain mail infrastructure.
In email deliverability terms, ServiceNow appears as an SPF include mechanism in domain authentication records. Its footprint skews towards smaller and mid-market organisations—particularly those in the .com namespace—rather than the largest global enterprises. It is frequently deployed alongside Microsoft 365, reflecting its popularity in Microsoft-centric IT environments.

SPF authentication and shared mail infrastructure
When an organisation uses ServiceNow to send email, it must authorise ServiceNow's mail servers in the domain's SPF record via an include mechanism. This delegates outbound mail authentication to ServiceNow's infrastructure. Unlike dedicated mail servers, this creates a shared reputation pool: the sending IP address space is used by many ServiceNow customers, so any one customer's mail behaviour (or spam complaints) can affect deliverability for others on the same infrastructure. Organisations should audit their ServiceNow mail configuration and monitor bounce rates and authentication failures to catch reputation issues early.

Frequently asked questions
Should I test email deliverability specifically against ServiceNow infrastructure?
If your organisation sends mail via ServiceNow, yes—test that SPF, DKIM, and DMARC are correctly configured for ServiceNow's mail servers, and monitor bounce rates and spam folder placement to detect shared-infrastructure reputation problems. If you receive mail from ServiceNow senders, treat them like any other external mail system and remain alert to spoofing or misconfiguration.
