Communication Channels
Configure email, WhatsApp, SMS, and Messenger notifications for customers
Overview
RevKeen's communication channels let you reach customers through the channels they prefer -- email, WhatsApp, SMS, or Messenger. Whether you are sending an invoice, a payment reminder, a receipt, or a dunning notification, you can configure which channels to use and customize the content for each.
Communication channels are built on top of RevKeen's notification engine, which handles delivery, tracking, and retry logic automatically.

Channel Strategy
Different channels work better for different situations:
| Scenario | Recommended Channel |
|---|---|
| Initial invoice delivery | |
| First payment reminder | |
| Urgent overdue reminder | SMS, WhatsApp, or Messenger |
| Payment receipt | |
| Subscription renewal notice | |
| Failed payment follow-up | SMS, WhatsApp, or Messenger |
Multi-Channel Configuration
You can configure a delivery sequence when multiple channels are available:
- Primary channel -- The first channel attempted (usually email)
- Fallback channel -- Used if the primary channel fails or goes unread after a configurable period
- Escalation channel -- Used for urgent communications like final dunning attempts
This ensures important billing communications reach customers even if they don't check one particular channel.
