PLEASE ADD EMAIL ID FILED IN MERCHANT PANEL.
SO THAT WE CAN ADD MORE DETAILS OF CUSTOMERS.
IT WILL BE EASY FOR US TO MAINTAIN ONE DAIRY OF MAIL IDS FOR FUTURE DISCOUNT OR OFFERS.
We will try and add this feature. The issue is not all the merchants want to share the customer email id and it is an additional field to fill.
We will look into this.
Thank you for your feedback.
