In Building your subscriber base we covered the set-up steps for integrating Buttondown with your existing social media presences, web sites, and long-term steps to make sure you're growing.
However, sometimes you want to just add a couple ad-hoc subscribers: a friend that mentioned they're interested in reading, or a couple of colleagues that you'd like to invite. For these use cases, an import is not necessary.
Go to the Subscribers page and click the "Add" button: a pop-up will appear that lets you enter an email address (plus some optional notes and metadata) and add new subscribers manually!
