When there are contacts that have been tagged (as a paying customer for example) in Ontraport, you will receive a text overview to Slack.
You can schedule the scenario to run as you need but adjust the filter in the first module accordingly. For example, if it runs once a day, only contacts that have been tagged in the last 24 hours should pass the filter.
This is a predefined template that will make the creation of your scenario much easier. Of course, you can always expand and customize the scenario to meet your own individual needs.
