Incentives

• Use incentives. If your newsletter is distributed via your blog or website, tell readers they will get access to something special if they sign up for the newsletter. For example, "Sign up for my newsletter and you'll automatically be entered into my weekly giveaway" or "Sign up for my newsletter and get a coupon for 20 percent off your next visit." Require the reader to sign up for the newsletter in order to get something she would miss out on otherwise.
  
  

Quality

• A newsletter with high-quality, useful information is more likely to attract and keep your readers. Spend the time to write informative articles or hire someone to help you if you have the funds. Include tips and tricks about your industry or business. Provide content that is actually helpful for people, not just promotional for your business. Once readers know they can rely on your newsletter for good information, they will be more likely to continue reading it and may even recommend it to others.
  
  

Style

• Newsletters tend to be more casual and informal than website content or marketing material. Use your newsletter to create a personal relationship with your clients or customers. Be friendly and accessible while still maintaining an authoritative voice. Write your content so it comes across as conversational and engaging to anyone. In a newsletter, it's generally OK to write in the first person voice or say "we" when talking about the company or business.
  
  

Promotion

• Your newsletter should be easily accessible for everyone. Promote it on your website, blog, business cards, brochures and marketing materials. Readership can increase only if people know about your newsletter. Ensure it is easy to find on your website. Mention it to clients or customers who want to know more about your business. In many cases, people will be willing to sign up for your newsletter if you make it accessible and simple for them to subscribe.
