How to save customer's emails?

[Honeybones]

We ran our first even last night and sold some products that will require collection at a later date so need to contact the customers. The first couple of customers entered their email address to send the invoice to but were not added as customers. I assumed there would be a record of the email address that was entered but I can’t seem to find it, is there a way to do this?

Hi @Honeybones!

So when customers enter their email after a purchase- that is just to send digital receipts to but not for email collection.

In order to have their email on file under > Customers, you would have to manually enter them in to the Customer Directory yourself before or after the sale.
