What CRM does

CRM is part of every store and always on. It lives under Marketing:

• Audiences — groups of customers built from rules, for example "bought from Sarees in the last 90 days and agreed to marketing". Audiences update by themselves as customers buy, sign up or move.
• Campaigns — a message to an audience by Email or SMS, optionally with a discount coupon made just for that campaign. You see how many were sent, opened, clicked and converted.
• Subscribers — your newsletter list.

SMS needs an SMS provider set up in Settings → Messaging (SMS Notifications). Email uses your store's email settings.

Only message people who agreed to marketing. Use the Marketing consent or Newsletter subscriber condition in your audiences.
