Hi, i have a online store without payment and im using the gravity forms to place the order, you can see here http://www.sitrana.com/comprar/
At the moment im reciving emails all the time and i would like to register users and create a new account for them if they purchase a shoe so i can have a customer database, but the problem is , if they purchase once the user will create a new account but when they decide come back and purchase again and use the same emails as the first time, the registration user will say the email address is all ready use so the customer will need to use a new one, what we can do whith that?
and the second question is: how i can parse the users i have in entries (855) to users so i can create a new database with all the customers had made contact with us? i will need to use mailchimp to store every contact in a database?
i need help to figure out what i can do
Thanks
