The InboxGeek system will retrieve all of the lists in your Ongage account. In order for your integration to perform, a list size of at least 30k is recommended. If a list size of under 15k is integrated, the longevity of the performance will be shorter in comparison to a larger list.
Select the list that you’ve created/chosen to use with InboxGeek.
NOTE: InboxGeek will filter and suppress duplicate contacts to prevent sending numerous events to a single contact.

Once your list has been selected, InboxGeek will display a second drop-down, Segment.
Select the segment you’ve chosen to use with InboxGeek and then click Next.
