I'd like that when a user subscribe the newsletter in a certain post of my blog, he is automatically added to a specific mailing list according to the post he is reading: different post, different mailing list.
I know I could let the user choose which mailing list can subscribe, but I'd like to make the subscription process more friendly.
A solution could be to load the post page with the relevant mailing list tick box already ticked.
Can you help me to do it? or any other ideas to have the same result?
Thank you very much! :)
