# Notification Templates

> Create and manage custom notification templates to control how Collate notifications appear across all communication channels.

# Notification Templates

Notification Templates control how Collate notifications appear across all communication channels (email, Slack, Teams, Google Chat). Instead of managing separate formatting for each channel, you define a single template using HTML and Handlebars templating language, and Collate automatically adapts it for all channels.
