Buttondown Documentation
Buttondown makes it easy to manage multiple types or segments of subscribers using tags, but sometimes that’s not enough. If you want to be able to completely separate out multiple verticals of a newsletter, keep track of different archives, or have two entirely different publications with different subscriber bases, your best bet is to set up separate newsletters entirely.
To add another newsletter to your account:
After you add a newsletter to your account, you don't need a new login or username or anything. Just open the same dropdown you used to add a newsletter. All the newsletters in your account are displayed there. Click any different newsletter to switch to it.
Buttondown bills you based on your number of total unique subscribers across all of your newsletters. If you have 2,000 subscribers in one newsletter and 1,000 subscribers in another and they’re completely disjoint (meaning that nobody is subscribed to both), you’ll be billed as if you have 3,000 subscribers; if all of the subscribers in that second newsletter are also subscribed to the first one, you’ll only be billed as if you have 2,000 subscribers.
