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.
