The one-sentence version#
Abandoned cart automation sends a timed series to shoppers who added items but did not check out, usually one to three messages over 24 to 72 hours, often with the cart contents embedded.
Why you should care#
It is consistently the highest-revenue automation in ecommerce because intent is already proven.
The mental model#
Think of abandoned cart emails as a contract between you and the mailbox providers receiving your mail. You publish or configure something they can check; they check it on every message; the result feeds their decision about where your message lands. Everything below is about making that check pass consistently.
Your first setup, step by step#
- Capture email early in checkout or via identified sessions.
- Send the first message within an hour, the second at 24 hours, and an optional third with a modest incentive.
- Embed the actual products with images and a one-click return link.
- Suppress if the purchase completes at any point.
Words you will see#
- Mailbox provider: Gmail, Microsoft, Yahoo, Apple, and the corporate gateways that decide where mail lands.
- Authentication: proof that a message is from who it says it is (SPF, DKIM, DMARC).
- Reputation: the provider's running score of your domain and IP.
- Placement: whether a message reaches the inbox, spam, or is rejected.
Common mistakes#
- Discounting in the first message, training shoppers to abandon.
- Sending to carts that were already purchased on another device.
Frequently asked questions#
