Customer sync between Joomla and Eshop

Hello,

I have a website where the users have to login at first to see the webshop.
When they login to the website they already have an email registered to that account. 
I do not want Eshop to ask the user for another email address, how do I do that.
I have tried to migrate the users to Eshop but it keeps on asking for an email address. 

What am I missing?

Thank you,
Greetings Gerrit 

Hi again Gerrit,

You can use Joomla Users Tool in EShop to sychronize data between existing joomla users and EShop customers. Please read more about it here: eshopdocs.joomservices.com/system-manage...ls#joomla-users-tool

I hope this is useful.

Sincerely, Giang
