Hi guys I find myself in the following topic: There will be a functionality that if someone leaves the shopping cart that was sent an email to remind you that your products are pending regards
Not sure what is your question, but functionality which you're mentioning is "abandoned cart". There are plenty of free and paid extensions out there, just google for "magento abandoned cart extension".
Advanced Abandoned Cart Report provides more insight and the additional information for Abandoned Cart Reports.
