Discount codes are not appearing in the emails sent by Mailchimp

Sometimes Personal Discount codes are not appearing in the emails sent by Mailchimp.

To prevent your emails being sent without a discount code, make sure to add the “Discount Code is not blank” conditionto the automated email in Mailchimp. This way, you can be sure that not-including-code email will never be sent to any customer. Mailchimp will send the email only after a discount code has been generated and assigned to a contact's profile.
