Definition
Customer success emails are automated or manual communications designed to help customers get maximum value from a product or service they have purchased. Unlike marketing emails (which focus on acquisition and conversion) or support emails (which react to problems), customer success emails proactively guide customers toward achieving their goals.
Effective customer success emails reduce churn, increase product adoption, improve customer satisfaction, and generate expansion revenue through upsells and cross-sells.

| Feature adoption | Ongoing | Introduce features the customer hasn't used |
| Best practices | Periodic | Share tips for getting more value |
| Milestone celebrations | At key achievements | Reinforce progress and commitment |
| Health check | Regular intervals | Assess satisfaction and identify risks |
