According to Live Direct Marketing's daily Tranco top-1M scan (July 13, 2026), Chargebee is the SaaS sender for 321 domains — 0.05% of 617,702 SPF-publishing domains. Detection method: include: mechanisms in the SPF record.
Chargebee is a subscription billing and revenue operations platform operated by Chargebee, Inc. It sends transactional and marketing emails on behalf of subscriber domains — invoices, renewal notices, dunning campaigns, and related subscription lifecycle messages — and thus appears as an SPF include mechanism in the DNS records of sites that use it.
Chargebee's footprint leans heavily toward the long tail of smaller and mid-market sites (rather than the largest enterprises) and concentrates in the .com space, where it is often deployed alongside Google Workspace as part of the typical SaaS stack. For email teams, Chargebee's sending reputation and infrastructure practices directly affect inbox placement for all subscriber domains that rely on it.

Chargebee operates a shared sending platform where thousands of unrelated subscriber domains send email through the same infrastructure, meaning all sites collectively own its IP reputation and DKIM/SPF configuration. A single compromised or misconfigured tenant can degrade reputation across the entire platform, creating a concentration point where one actor's misuse affects thousands of ostensibly separate domains. Deliverability teams should actively monitor their Chargebee integration, as email success depends partly on how responsibly other Chargebee customers use the platform.
