Thank’s Carles!
These days all we are overloaded with SPAM.
So, the idea is to let registered user what mailing he/she wants to keep getting. We do topic-oriented mailing lists: one for executives, another one for stress engineers, next for structural engineers etc.
All this effort is focused on avoiding SPAM.
The most efficient would be: 1.) to have list of all available mailing lists at customer profile 2.) let user select mailing lists he wants to subscribe in the widget or dedicated “My subscriptions” page/post.
What do you think? ??
Solution provided above is nice and effective but requires administrative work, as users cannot sign in and review all lists they ar in.
