Guests and signed-in shoppers

A reminder can only be sent if CartWhizz knows the shopper's email address.

Who can be reached

• Signed-in customers — always, using the email on their account.
• Guests — only if they typed their email address at checkout before leaving. Guests who added products but never started checkout cannot be reached.

Shoppers who log in with a phone number and have no email on their account cannot be emailed.

Getting more emails

• Ask for the email early in checkout.
• Encourage sign-in, for example with reward points or faster checkout.

A cart is tied to one browser for guests

A guest's cart lives in their browser. If they clear their browser data or switch phones, the old cart can't be found — but the reminder email still works, because the link refills a new cart.

When a guest later signs up

If a guest leaves a cart and then creates an account, you may see two abandoned carts for the same person. When they place an order with that email address, both stop.

Marketplaces

On a multi-seller store, one reminder lists all products in the cart, from every seller. Sellers cannot run their own reminders.
