Yes, there is! I'm happy to show you how you can do a query search for a customer based on an email.
You can use the Search feature to search for a customer using a part of a keyword from their email address. Simply click the Magnifying glass icon, then enter a portion of their email address. The results will show from the matching keyword.
Alternatively, you can use the Customer Contact List report to look for a particular customer. Go the the Reports section, search for Customer Contact List, then click the result.
There are other things you can do on the Search function. Please check this article for more details: Search for transactions.
