Hi, I want to integrate shipping easy with nopcommerce but in order to register I need to choose an ecommerce platform where nopcommerce isn't listed. So the alternative is to call a number or send an email. I sent an email from my gmail account but received an error stating: "We're writing to let you know that the group you tried to contact (code) may not exist, or you may not have permission to post messages to the group".

I don't want to call the number so how should I proceed?
