The InboxGeek system will retrieve all of the tags in your HighLevel account. In order for your integration to perform, it is recommended to have at least 30k contacts tagged. If less than 15k contacts are integrated, it is unlikely to see any results from your integration.
Select the tag that has been applied to the contacts that you are choosing to use with InboxGeek and then click Next.
InboxGeek will move you to the next tab, Integration.
