In a Word, Yes!

Publishing a newsletter as a part of your marketing campaign can increase the potential profit from existing customers becoming long-term buyers.

Newsletters gives us a tool for collecting the email addresses of targeted visitors with the intent of turning them into paying customers.

Utilizing this tool also gives us the means by which we can remain in contact with an additional valued resource,"The Previous Customer."

If You want to keep customers, A Newsletter is a must.

If you don't have a Newsletter, you have no way of following up with your paying customers, or for that matter, any potential customers. Someone that has purchased from you once is very likely to purchase again. You don't want to run the risk of losing that person because you don't have a follow up method in place. A Newsletter.

The standard for publishing your newsletter is generally once a week. You may want to publish bi-weekly. If you find something of value that your customers might have an interest in, you don't have to stand on ceremony, you can notify them at will. The frequency of your publication will really be determined by your marketing niche. Who and What your marketing.

Your topics will be determined by your area of expertise. If your knowledge is limited, you may have to do some research in order to keep your subscribers informed, There is no shortage of pre-written articles, on any topic, you may be looking for. With Article Directories, such as this one, that abound the Internet, your search will be an easy one.
Of course you can always do the research and write the articles yourself, based on what you've learned. You also may want to consider subscribing to a Private Label Content site. You'll have access to pre-written articles available for re-write.

Your newsletter doesn't have to be "The Great American Novel." (:-) Quite frankly if it's too long, your readers probably will lose interest before they finish reading it. Sometimes a quick announcement about a New Product or Service will be sufficient. Other times a short 400 to 500 word article will do the trick. It will really depend on what you're trying to convey to your readers.

You'll also need to be consistant. With the thousands of newsletters that are available. You'll want to avoid having your newsletter mistaken for spam. Announce your publication in the subject line and don't forget to personalize it by inserting your subscribers firstname.
