The Rules Engine lets you create if-then automation rules that respond to label changes on members. When a label is added or removed, rules can automatically subscribe or unsubscribe the member from specific newsletters.

​
How rules work

A rule has three parts:
  1. Condition: What event triggers the rule (label added or removed)
  2. Audience: Which members the rule applies to (by status, tier, or labels)
  3. Actions: What happens when the condition is met (subscribe or unsubscribe from a newsletter)
When the trigger fires, Outpost checks whether the member matches the audience criteria. If they do, all actions run.

Apply timing

When selecting “Apply to all subscribers now,” a confirmation dialog shows the number of members who will be affected. Review this count carefully before confirming.

FAQ

The Rules Engine responds to label changes and manages newsletter subscriptions. The Autoresponder is for sending email sequences triggered by registration, renewal, or other lifecycle events. They complement each other: use labels to connect the two.
Yes. When creating a rule, choose “Apply to all subscribers now” to run it against all existing members who match the criteria. Otherwise, it only fires for future label changes.
All matching rules run independently. If two rules both subscribe a member to the same newsletter, the duplicate subscription is simply ignored.
No. The Rules Engine only manages newsletter subscriptions (subscribe/unsubscribe). To send emails based on conditions, use the Autoresponder with a “Member Label Added” start condition.
