Allow unsubscribed contacts to resubscribe

I would really love the option for unsubscribed contacts to be able to subscribe again when they fill out a form.

Right now, if someone unsubscribes and later decides to sign up again, they remain unsubscribed. In today’s world, where people often unsubscribe temporarily and later come back when they are ready, this feels like a big limitation.

It can also mean lost business opportunities, because someone who is genuinely interested again cannot easily rejoin the email list.

It would be very helpful if SendFox allowed contacts to actively resubscribe through a form, confirmation email, or preference page, so they can clearly give permission again and start receiving emails.
