you can't do much without optins nowadays... try the old bait & hook.
go on facebook and look at pages for gamers (razer, steelseries, etc) which do giveaways.
both splurgy and rafflecopter have an option to get more entries based on referrals.
go to spurgy or rafflecopter and create a fake giveaway.
send them an email with 'top 5 gaming giveaways of the week' and include yours.
to sign up into a giveaway done through splurgy the user optins into your list.
seeing your fake giveaway next to razer/steelseries/valve etc real ones will make them more eager to sign up to yours as well...
sit back, relax and collect optins.
after that email them cr4p.
btw splurgy is free for 1000 signups... but if the list is scraped I am 100% sure you won't have more than 1000 signups
