Thanks for your note.
Instead of sending a press release to hundreds of media members, try contacting the editors via phone directly with your pitch.
Prepare a unique story idea for each person in advance and provide valuable information. For help, see our 7 steps at http://www.startupnation.com/steps/77/steps-successful-public-relations.htm.
This does take time, but it is the way to get media attention and publicity that can be worth thousands in advertising dollars. If you just don't have time to pitch the media, you may want to check into hiring a PR professional to help you.
Hope this helps.
