How do I add Proactive Alerts?
If you are just posting your Sponsored Casting Call, you just check the box next to Proactive Alerts.
To add Proactive Alerts to an existing casting call:
- Edit your casting call
- Choose the Proactive Alert option
- Save the changes
- You will be taken to a review page, and then an invoice page.
You will need to pay the Proactive Alert fee in order to activate the feature.
