Subscribers
Most themes include a newsletter section customers can sign up through — every signup lands in Growth → Subscribers.
Where subscribers come from
The newsletter section in your theme (enable and place it via the theme editor) collects an email address and adds it to your subscriber list — no separate signup form or third-party tool needed.
Managing your list
The Subscribers page lists everyone who's signed up, with when they joined. It's a running record you can export and use with whatever email tool you send campaigns from — Forma captures the list, it doesn't send marketing emails on your behalf.
Subscriber count on your dashboard
Your subscriber total is one of the six KPIs on your dashboard home, so growth in your list is visible right alongside revenue and orders. See Analytics.
