I recently ordered a swimsuit online to get ready for a beach vacation. Choosing between hundreds of swimsuit styles after months in sweats is overwhelming, so I breathed an audible sigh of relief when I saw the order confirmation in my inbox.

I could almost smell the ocean and feel the sand under my feet in that moment.

That “shopping high” is a feeling of instant gratification and anticipation after an order. You can leverage this valuable window to boost customer loyalty and retention as a brand. To achieve this, you need the post-purchase email.
