Why Docebo (LMS) appears in this category
Docebo — Canadian cloud LMS for enterprise learning, sending course enrollment and reminder notifications.
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.
Docebo is a cloud-based learning management system operated by Docebo Inc. that enables organisations to administer online training, courses, and employee development programmes. It sends transactional and marketing emails—such as course notifications, login credentials, and enrolment confirmations—on behalf of customer organisations, meaning its mail servers become part of each customer domain's email infrastructure.
Docebo's presence in email infrastructure is concentrated among smaller and mid-market organisations rather than Fortune 500 enterprises, predominantly within the .com domain space, and frequently appears alongside Microsoft 365 deployments. For email professionals managing authentication or testing deliverability, this means Docebo's SPF includes are more common in medium-sized corporate and educational configurations, warranting consideration in multi-provider email assessments.

SPF include mechanisms and authentication delegation
Organisations using Docebo typically authorise its mail servers via an SPF include mechanism in their domain records. This distribution of sending authority between the customer's SPF policy and Docebo's infrastructure means deliverability and authentication testing across Docebo-using organisations requires validation of both the customer's SPF configuration and Docebo's mail-sending reputation, particularly when Docebo coexists with other SaaS providers like Microsoft 365.
