About Customer.io

Customer.io is a versatile messaging platform that enables teams to create and send targeted communications based on real-time customer behavior and data. The platform supports email, push notifications, SMS, in-app messages, and webhooks in automated, data-driven workflows.

Unlike traditional email marketing tools, Customer.io is built for behavioral targeting, allowing teams to trigger messages based on specific user actions, attributes, and segments. The visual workflow builder makes it easy to create complex multi-channel campaigns without engineering support.

Customer.io serves both B2B and B2C companies, with particular strength among product-led growth companies that need sophisticated event-driven messaging. The platform's data-first approach and developer-friendly API make it a popular choice for technical teams.

Sync Customer.io with Cubbie

Cubbie connects straight to the Customer.io admin API, so your seats, usage, and plan stay current without anyone updating a spreadsheet. That is what turns renewals and unused licenses into something you can act on.

Workspace list and high-level usage metadata (people count, object count, monthly billable emails) via GET /v1/workspacesRegion (US/EU) the account lives inNote: no admin-seat roster or per-seat activity is available from Customer.io's App API (team members are SCIM-only), so licensed-seat, active-seat, and dormant-seat counts are reported as not-available

Connecting takes about a minute. Paste a read-only key from your Customer.io admin settings. Cubbie never writes to your account.
