What is your newsletter for?
A newsletter is the one audience you own. Social sites can change the rules; an email list is yours. People join from your Brand Page and Link in Bio, and appear below. Get subscribers: Share your Brand Page or Link in Bio. Both have a sign-up built in. Write an issue: Use the Ask button at the top, review it, and approve it in Messages. Send it: Press Send above, or choose a day and time in the Calendar, to everyone or just one tag.
