After launch, senders, schedule, and exclusions stay locked until you select Edit campaign. You can still enroll leads below that lock.
Unlock senders, schedule, and exclusions
Active campaigns show this banner: "Edit campaign to change senders, schedule, or exclusions. You can still enroll leads below."
Open the Active campaign and go to Settings.
Read the lock banner.
Select Edit campaign.
Change senders, schedule, or the exclusion toggles, then save.
Enroll more leads from the enroll control without waiting on that lock.
Sequence edits follow the lock on the page. If a step control is locked, use Edit campaign first. InMail cannot launch. If you add InMail while editing, Review will block until you remove it or switch to Message.
What you can do without unlocking
Enrollment stays available. Pause and archive stay on the campaign list. You do not need Edit campaign to stop sending or to add more people from a list.
