Is it possible to create a personalized list from the customers who signed up for mailing in the receipt form?**

Yes!

Click on Contacts > Lists > Create New > Custom List

Using Custom List you can filter the list by marking which consents are relevant and what is the time period you want.

In addition, you can create rules for those who signed up for mailing from the receipt. For example, customers whose purchase amount was over 100 NIS.
