Hello @happybabyclass,

Thanks for sharing your question with the Klaviyo Community!

Since you are trying to send a one time reminder email to contacts who have purchased one of these classes, I would suggest sending these reminders as a campaign email scheduled for the day before the designated class dates.

You can do this by creating segments capturing customers who have purchased each of these class variations and then using these segments as the recipient group for your emails. You can create these segments by using the definition of “What someone has done, Ordered Product at least once where Name equals X”. For example, to target users who have purchased the “3rd July” variation, you can create your segment with the rule of: “What someone has done, Ordered Product at least once where Name equals 3rd July”. You also can replace “Name” with any other defining dimension you want. 

With these segments created capturing each of these variations, you can create and schedule a reminder email to be sent out the day prior of these classes occurring. 

As a bonus, you can also schedule your campaigns in advance to automatically send out the day before each of these class by designated the date and time you want the campaign to be sent out at. Keep in mind that if you decide to schedule your classes in advance, I would also recommend ensuring you are using the Determine recipients at send time option. This feature will allow Klaviyo to double check and re-evaluate the recipient list to ensure that it is as up to date as possible before sending. 

Thanks, and have a great weekend!
