Hi @Julian2 ,
Just a few things to note:
Our abandoned cart recovery system only works for certain channels. These include Online Store, Buy Button or our Plus Wholesale channels.
If any orders are placed through third-party channels as well as POS, while an abandoned cart is still created, the system doesn’t send recovery notifications to these specific orders. Additionally, some third-party apps may use the Draft Orders API in which case abandoned cart notifications do not send, as they did not originate in the Shopify checkout. You can read more about this in our help documents.
Something else to consider, if your abandoned cart emails are being sent to some customers, but not others, you’ll want to double check that the option to send these emails is set to: “anyone who abandons their checkout” VS “Email subscribers who abandon their checkout”, otherwise only customers that ticked the “subscribe to email” box at checkout will receive the abandoned cart recovery emails. Hope that makes sense!
To access where to check or make changes to this setting, head to Settings > Checkout > Abandoned checkout emails.
Please let me know if the above information solves the issue!
