Emails??

I am planning to make a website and in that I am thinking to make a newsletter and every time people sign up they will get some thing.
But i dont know what should I provide them through newsletter? ebooks, products??

What do you do?? Or is my question wrong??

With a newsletter you need to provide your readers with useful information about your topic, and only after you have given them useful information you can offer them a product.

Or are you looking to give something away with every signup? That could work well as a tactic.

The newsletter should keep your readers up-to-date with your content. If you offer them a product as a reward for signing up, they should be motivated. You can choose an ebook related to your content, a discount coupon or even a product or a free service.

Giving Free e-report is the best way to get subscribers that are relevant to your niche. Also inform them that they will get up do date news when they subscribe so they are at least ready for your future emails.
