Your subject lines plays a crucial role in any email campaign ads whether you're using safelists, autoresponders, ezine solo ads or any opt-in list where email is involved. Your subject line will make or break your return on your investment so make sure you get their attention first.

Here are six headlines that have worked for me in the past which I'm sure will work for you too in the future. The technology will always change but peoples desire to succeed and curiousity will not.

1. Promote Your URL Here - Free!

For whatever reasons, I've had so much success using this subject line when promoting free classified sites, safelists, and those viral ad boards.

2. Hi, My name is Paul

This works simply because it raises prospects curiosity. I'm always a sucker for this subject line. Who's this Paul anyway?

3. I need your help, please?

There's something about being a human, always wanting to help another human being, It's hard to explain, it just works.

4. Bob, I haven't received your shipping address yet.

What! my shipping address? why do you need my shipping address for. This particular subject line really piqued my interest.

5. How my site got listed #1 on Google, for free!

This one made several sales from Trafficswarm traffic exchange program when I was promoting an affiliate program about search engine e-book. Even made more sales with ezine solo ads using the same subject line.

6. Paul, Please accept my sincerest apology.

When I saw this subject line from an email, my first reaction was, "who/why/what are you sorry about?...huh?" Exactly it got my attention and my curiosity. The sender was apologizing for not sending that email sooner which was about a new traffic exchange program. Good grief.

In conclusion, make your subject line so compelling that it's almost irresistible for your prospects not to open the email message. If you can hypnotize your readers with cleaver subject lines, you are half way to making a sale.

Of course, I am not recommending that you use any of these headlines if they are not true in relation to the content of the e-mail message. If you rely on deception in e-mail marketing, all you will do is tarnish your reputation and make it that much harder for all internet entrepreneurs.
