Customer.io price alerts

One-line email alerts when Customer.io changes published pricing. No marketing, no nurture sequence — only the alert and the source link.

We send an alert only when the Price Sensor confirms a list-price change on https://customer.io/pricing. Unsubscribe with one click from any alert. Your email is stored in Cloudflare D1 and never shared.
