My site gives wallpapers to visitor in 6 different resolutions. I use to update the site frequently with new wallpapers. What new I'm thinking is to give all the new wallpapers in single compress file (rar or zip). And to get the file, one has to provide his name and email address. So, whenever I update my site, I'll send a notification email to all of the subscriber with the download link, which will only be accessible to them. Will this help to get people back to my site? as i have only 15% of visitors visits my site more than one time (Daily unique visitor count is 150-200). Will this help making those subscriber as a referral to my site? (resulting in increase of traffic) I'll have a list of subscriber, What is your opinion? will that list help me in my next website launch? please advice. my site is : www.getcarwallpapers.com
