How to check whether a customer has placed another order since beginning the post purchase flow?

[empiricalarby]

Hi there.

I'm using a post-purchase flow that targets customers who buy samples of my product.

The goal is to remind them to buy a full size order if they liked the sample. But I don't want to send them an email if they've already come back for more. I only want to send the email if they've not placed another order since buying the sample. How do I do that?

Here's my current attempt:

I'm struggling with the 2nd to last box, which says "check if created at is equal to order customer last order created at". The goal is to check if their last order was a sample order, so that I can remind them to order a full size order if they liked it. I'm finding it very confusing to determine whether I'm selecting the right condition, since there's no way to test whether the flow actually works without waiting many days.

Thanks

Can you show what is in your condition?

That condition would check if the last order date is the same as the order that started the workflow. So if it's true you know they haven't purchased any product. But I suspect you want something that is specific to the SKU. For example, they could've purchased any product. 

Doing that latter thing is more complicated and depends on your store. For example, how would you know that a sample is related to full size product? Are they different variants of the same product? Does one always have "sample" in a product attribute or a tag?
