Why Automattic (WordPress.com / Akismet) appears in this category
Automattic — WordPress.com, Akismet, Jetpack notification email.
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.
Automattic is a web-software company that operates WordPress.com (a hosted website-building platform), Akismet (a comment and spam-filtering service), and several other SaaS products. When a domain is hosted on WordPress.com or uses Akismet for email-based notifications and comment moderation, Automattic's mail infrastructure handles the sending of transactional and bulk emails on that domain's behalf.
The presence of Automattic's SPF mechanisms across high-traffic, enterprise-tier domains in the .com namespace reflects widespread adoption of WordPress.com hosting and Akismet integrations among established websites. The pattern of Automattic appearing alongside generic or unmatched mail-exchanger records suggests that many hosted sites rely on Automattic's shared infrastructure for outbound mail, which has deliverability implications for both senders (who must declare these third-party senders in SPF records) and receivers (who evaluate mail from Automattic's IP ranges against the broader reputation of the WordPress.com tenant ecosystem).

SPF declarations and shared infrastructure on WordPress.com
WordPress.com-hosted sites typically publish SPF records that include Automattic's mail-sending IP ranges via dedicated include mechanisms. Because WordPress.com is a multi-tenant platform, individual site domains do not control the underlying mail infrastructure—Automattic manages outbound delivery from a shared pool of sending IPs. This means a site owner's SPF record must trust Automattic's include, and receivers evaluate mail reputation partly on the aggregate sending behaviour of all WordPress.com tenants sharing those IPs. Site administrators should ensure their SPF records correctly declare WordPress.com's mechanisms and avoid SPF flattening (replacing includes with static IP literals), as Automattic may change IP ranges over time.
