Why AFAS appears in this category
AFAS Online — Dutch ERP/HR cloud.
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.
AFAS is a Netherlands-based SaaS platform for email delivery. Organisations use it to send email on their own domains through AFAS's infrastructure, authorising it via an SPF include in their DNS records.
AFAS's footprint is concentrated in smaller and mid-market organisations rather than large enterprises, and is particularly prevalent in the Netherlands and adjacent regions. It is often deployed alongside Microsoft 365, suggesting organisations that combine Microsoft-hosted mail systems with external sending infrastructure. For email receivers and reputation systems, AFAS appears as a regional sending platform in the long tail of email infrastructure; its presence in an SPF record signals a sender's reliance on delegated sending capacity.

AFAS as an SPF delegate and its role in regional sending infrastructure
When a domain authorises AFAS to send on its behalf, that delegation appears as an SPF include in the domain's DNS record. This model allows AFAS to manage sender authentication and reputation independently, a standard architecture for third-party email platforms. For reputation systems and email operators, an AFAS include typically signals a mid-market or smaller sender, particularly in the Netherlands, that uses external infrastructure for sending workloads.
