The consent rules Repeatly follows, why some customers are skipped, and how to change the policy deliberately.
This is the setting worth understanding properly, because it is both a legal question and the most common reason a merchant asks why so few reminders went out.
Out of the box, Repeatly only emails customers who accepted marketing at checkout. In Shopify this is the customer's email marketing consent state. If your checkout does not show a marketing opt-in box, almost nobody will have accepted, and your recipient list will look empty.
You can enable that box in your Shopify admin under Settings → Checkout, in the customer contact section.
Open the recipients page and search for their address. The status badge answers the question immediately: active, no consent, or unsubscribed. If they are active and still received nothing, check whether the product has a learned interval and whether the reminder is scheduled — the upcoming sends list shows the next seven days.
If anything here was wrong, unclear or out of date, tell us — the article gets fixed the same day.
