Can someone point me in the right direction to understand how to add a brand new subscriber and add them to an existing automation when I do? The automation is set up so that when the subscriber is tagged with a particular tag as a result from clicking on a specific link they get the sequence started... What I want to do is add subscribers one at a time and when I do have them move into that sequence. I have been simply adding the tag and yet it does not seem to add them to the automation. Hopefully this makes some sense?
