There's no way to set entry and exit criteria on the campaign itself. To start a campaign when a contact meets a condition and stop it when they no longer do, we have to build a separate automation. That makes it hard for providers to set up on their own and needs several steps for something they'd expect to be a campaign setting.

Example: a welcome campaign should start when Lifecycle stage is Prospect and stop when it changes to anything else. Today that takes an automation with two branches. Sending a campaign based on custom object data (for example, every parent whose child attended a class last year) takes a list, then an automation, then enrolment.

What we'd like: Start and stop (exit) criteria set directly on the campaign, using the same filters as lists, including custom object fields.
