A customer finds a sold-out variant, leaves their email in a small form from your theme editor, and confirms if you use double opt-in. The moment stock is back, they get one email from your own domain, in the language of the page they signed up on. You set the rules: a minimum stock before anything goes out, waves so the people you notify can still buy, or pausing a variant to time a launch. Templates per language, exclusions per variant or collection, stats on delivered, opened and bounced.

• Send restock emails from your own verified domain.
• Let customers confirm their email with optional double opt-in.
• Set stock thresholds and send in waves to match available inventory.
• Customize email templates for each customer language.
• Track email delivery, opens and clicks, and export your waitlists.
