Mailshots & Campaigns - support 'opt-in' as well as 'unsubscribe'
At the moment when you send a campaign mailshot, you can include an 'unsubscribe' page which allows people to unsubscribe from all future mail, or from individual campaigns which they've *already* received email from.
We'd like to extend this so you could include future possible campaign mailshots on the same page, allowing opt-in as well.
eg: You run one general 'Newsletter' mailshot to all customers, but use that page to allow them to opt into more specific campaign newsletters on sub-topics if they wish to.
Or a one-off campaign mailshot after an exhibition to new leads allows people to opt in to your general newsletter campaign.
(Where 'opt in' obviously means they've not received a mail from that campaign before).
We don't want to show all campaigns on the subscribe / unsubscribe page (many are internal only) but a 'Allow mailshot opt in' flag or something along those lines on each campaign might work.
