Here are some of the main features of Sonic Opt-In:

• Steps 1 through 4 create your opt-in page, then only 2 steps to get it up and running on your site!
  
• Audio can be included in your opt-in page -- a special control is included. You can also choose whether the audio is autostart or manual start.
  
• Would you like a series of bullets in your copy? (These things you're reading now are bullets.) Special bullet editor allows you to include as many as you like!
  
• The prospects name and email are required.
  
• People who have already opted in are taken automatically to your sales page -- no getting stuck behind the opt-in page again!
  
• Prospect can be taken to a special page targeted exactly to their interests.
  
• Depending on the prospects answers, subscribe them to different autoresponders. Now you can create sub-niche lists with ease!
  
• Personalize your sales page -- when you use the prospect's first name in your copy it increases conversions.
  
• Use one of the built-in HTML templates or create your own.
  
• Works with Aweber, Get Response, 1 Shopping Cart, Email Aces, etc., most of the major autoresponder services. Just requires the ability to subscribe to a list via an email address.
  
• Even works without an autoresponder account for people who are just interested in the personalization feature.
