Pantheon — managed WordPress and Drupal hosting platform whose local MTA can send site email.
Directory category: Saas. The classification comes from include: mechanisms in the SPF record. It describes observed DNS infrastructure, not a commercial relationship and not the placement of any individual message.
Across 10 distinct TLDs its top three are .org (37.8%), .com (34.1%), .edu (13.4%) — together 85.4% of the 82 domains, which makes the footprint narrow — three TLDs cover most of it, which is typical of a regional or single-market operator. The service most often observed on the same domains is Microsoft 365 (Mailbox, 31 domains, 37.8% of them), followed by Google Workspace (35.4%). Directly comparable by the same detection rule: Shopify, Pardot (Salesforce), CodeTwo Email Signatures 365. Ranking between them reflects what is published in DNS, not delivery quality or volume sent. All figures come from a single daily DNS snapshot (2026-07-25); a domain appears here when its published records match the include: mechanisms in the SPF record rule, which is an infrastructure fact, not a commercial relationship.
