Why Chargify (Maxio) appears in this category
Chargify (Maxio) — subscription billing platform.
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.
Chargify, now operating under its parent company Maxio, is a SaaS billing and subscription management platform that sends transactional and marketing email on behalf of its customers' domains. The company provides email infrastructure integration so that subscription renewal notices, invoices, and other billing communications appear to originate from the customer's own domain rather than Chargify's.
Chargify's presence in email infrastructure is concentrated amongst smaller and mid-market organisations rather than large enterprises, predominantly in the .com namespace. The platform is frequently deployed alongside Google Workspace, suggesting it serves organisations that already use Google's email service and need to scale billing-related communications. For email professionals receiving or sending mail involving Chargify, this footprint pattern indicates a widespread but geographically dispersed user base of smaller companies rather than a dominant platform within individual vertical markets.

SPF publishing and authentication patterns
Chargify publishes SPF include mechanisms that allow customers to authorise the platform to send email from their domains. This delegation pattern is common amongst transactional email providers: rather than customers maintaining their own mail infrastructure, they add Chargify's SPF record to their domain's authentication policy. When Chargify sits alongside Google Workspace in the same domain's SPF configuration, both services are authorised to send on the domain's behalf, creating a layered authentication setup where DKIM signing practices and authentication chain integrity matter for overall deliverability.
