Firebase — Google mobile and web app backend platform sending auth, password-reset and project notification emails.
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 176 distinct TLDs its top three are .com (52.0%), .ai (4.9%), .io (4.9%) — together 61.8% of the 1,854 domains, which makes the footprint moderately concentrated, with a recognisable home market. The service most often observed on the same domains is Google Workspace (Mailbox, 1,089 domains, 58.7% of them), followed by Microsoft 365 (11.5%). Its share of SPF-publishing domains has not moved measurably in 30 days. 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 (2026-07-26); 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.
