We have a site a.com and b.com, and correspondingly a_list and b_list. We faced a small problem, when the user of "a.com" site is subscribed to a_list and then the same user using the same email on b.com site tries to subscribe to b_list. We receive the error 409: WE'RE SORRY! IT APPEARS THAT YOU ARE ALREADY A SUBSCRIBER OF OUR MAILING LIST." The code of the form is created using Constant Contact Signup Form Generator (CCSFG) Probably the lists are merged in the admin panel? Can we cancel this option somehow? We'll appreciate your advice on this point!
