Service Emails

Service emails keep customers informed about billing events that require awareness or action.

Use service emails for operational communication, not marketing campaigns.

Content guidelines

Every billing email should include:

  • Company name.
  • Customer name or account reference.
  • Invoice or quote number where applicable.
  • Amount due or payment status.
  • Due date or retry date.
  • Clear next action.
  • Support contact.

Deliverability checklist

  • Sender domain is verified.
  • Reply-to address reaches billing support.
  • Test emails render correctly on desktop and mobile.
  • Payment links point to the correct environment.
  • Live mode emails are not sent during test runs.

Dunning emails

Dunning emails should be configured with the failed payment policy:

  1. Payment failure notice.
  2. Reminder before retry or due date.
  3. Warning before suspension.
  4. Suspension notice if configured.

Use dry run before executing dunning actions so operators can review the affected customers.
