When you see that a Campaign is 'Locked,' it means that the campaign will run for your contacts that meet that criteria.
Typically these will come from your Team or Office Administrator.
The Campaign will always activate for the contacts that match that criteria, unless of course you modify the contact that qualifies it for a more specific campaign.
Typically, there are default campaigns that are designed to handle basic new buyers and sellers that sign up on your kvCORE site so that you don't need to design a campaign right away.
Dark Padlock - Campaign created at the administrative level that will run for the contacts that match the criteria of the campaign.
Open Padlock - Campaign created at the administrative level that is shared with you but not 'Locked' or mandated.
No Padlock - Campaign created by you, if you are not an administrator.
