Capture Email Addresses from Abandoned Carts for Remarketing

This article applies to Classic Commerce. (Looking for Contextual Commerce documentation?)


Potential customers who started, but have not completed, the checkout process are close to making a purchasing decision. Studies have shown that about 67% of online users abandon their shopping cart before completing a purchase. You can significantly increase conversion rates if you follow up with these potential customers. Don't give up on these customers so easily! Instead, FastSpring can easily and automatically capture email addresses of abandoned potential customers and send them to a list in your MailChimp account. There you can design remarketing emails to turn potential customers into actual customers.

MailChimp Setup

If you have not already, go to and get an account with MailChimp. Once you have an account, create a list that will be used solely for abandoned cart email addresses. If you are not doing so already, you may want to manage your mailing lists with MailChimp.

Open a Support Ticket with Required Information

Open a support ticket with us. In your support ticket, please provide the following information obtained from MailChimp:

  • The API Key 
  • The List ID (with the numerical id associated with it) for your remarketing mailing list

Note: Although MailChimp strongly suggests not giving your API Key to others, this is necessary to integrate with them. If you have already completed the setup described in Manage Mailing Lists with MailChimp, we already have your API Key, so you will only need to supply the List ID associated with your remarketing campaign. We can take care of the rest for you.

Once we set it up, emails of potential customers – who entered in their email addresses, but have not completed the checkout process for your store within 12 hours – will be passed on to MailChimp periodically (usually within 30 minutes) after cart abandonment.
