Engagement Rules

An Engagement Rule watches new comments on a connected channel and answers them with a public reply, and optionally a private message. Rules run on Instagram, Facebook Pages and X in the beta; other networks are not supported yet.

Build a Rule

1. Open Rules and choose New Rule.
2. Pick the connected channel and the post or account the Rule watches.
3. Add the conditions that decide when the Rule matches, such as a keyword in the comment.
4. Write the public reply and, if you want one, the private message. Use the language variants you need.
5. Publish the Rule. It starts matching new comments only after it is published.

Guardrails Murmalo enforces

• A comment receives at most one automated public reply and one private message.
• Every branch of a Rule must end in a reply, so a missing step cannot leave a comment unanswered.
• Automated replies carry a disclosure that the reply is automated. The disclosure cannot be removed.
• A person who opts out is not contacted again by a Rule.
• Messaging windows are respected: a private message is sent only inside the window the network allows.
• Automated replies never trigger another Rule, so a Rule cannot loop.
• Each channel has its own rate limit, shared by all Rules on that channel.

Versions and pauses

Publishing a change creates a new version of the Rule. Comments already being handled keep the version they started with. Pause a Rule at any time; a paused Rule stops matching new comments, and you can resume it later.

Testing

Before publishing, use the Rule preview to try a sample comment and check which branch matches and what the reply says. A Rule with no matching branch is reported before it can be published.
