Re: 5th Anniversary Gift to Perpetuum - Marketing Campaign
Zoom if you could commit to doing a Monthly update even if it was nothing more than a progress report to say, "Hey guys we are 75% done with XXX." Include stats from the killboard such as top corp, top agents etc. Links to any fan generated content etc and always include that flyer from the payment change model. Announce any upcoming sales on steam or ingame. Send that out via email to every registered email and keep doing so until they opt out.
A few days maybe to create a template and then a few hours a month to update and send. This will do loads for this game.
