The bottom line is stop starting again. If you've done so before, it might be too late to revive your old subscribers without being reported or attacked, if you're thinking about it, don't do it. Five hundred people are a gold mine on its own, and hey, only fifty more of these and you're at 25k already. If you have no idea what I'm going on about with all this giving up lists stuff, great. Take note and fix your organization and your situation before starting anything new, or you might just find yourself in the above situation and wasting the last few weeks, or even months in severe cases of your promotion time and budget. (I’m still amazed at how many actually throw prospects away).
