You can now add the person behind a reply to another campaign, so a yes on one sequence can start the next. Open the thread in Replies and press Enroll in another campaign in its header, then pick a Destination campaign. The reply's own campaign is left out of the list.
Ken adds the person to that campaign's Leads as a candidate. Enrolling sends nothing by itself. If they are already on it, Ken adds nothing. Ken will not enroll a contact with no verified email, one marked do not contact, or one on your blocklist.
On a thread linked to a campaign, Add colleague to campaign finds the person a prospect referred you to. Search by name at the prospect's company, or clear Only people at to search wider.
The reply Tag picker now has Out of office. Click a selected tag again to clear it.
