Creating your own newsletter is one way to build your credibility and visibility online. Since 2009, it has become the easiest and fastest way to connect with your prospects all over the world. The best part is that you do not have to all of the writing yourself.
Connect with several people who do something related to your niche. You can each write one article each month and include it in your newsletter. The others will be able to include their contact information at the end of their article, and that is sufficient as payment. The idea is that everyone can build their list and become both credible and visible in their niche.
If several of you want to also have your own newsletter, one article can be used more than once if necessary. I write every day, so I would prefer to write new content for everyone who asks me.
Find someone to lay out your information so that it is easy to read online. Long ago everyone had a text newsletter, but now we prefer to have full color and graphics. It is so easy to do this and it will make a difference in the experience of your reader.
Take this part of your online business seriously for best results. Make a commitment to put your material together once a month, or once a quarter if that is easier in the beginning. Once you see how quickly it can all be done, you will want to have the exposure once each month. You can promote yourself and your products easily by publishing your own newsletter.
