Email newsletters are easily one of the most powerful and cost-effective marketing tools a business has to generate both new and repeat business on a regular basis, yet many business owners who decide to start a newsletter make one big mistake that can actually end up creating a huge headache in the log run -- potentially costing time, revenues and reputation.

Without taking into account the finer details of copywriting such as action words and key phrases that can make your email marketing campaign much more effective, the act of putting together the text and content you want to convey in your email newsletter is easy enough. However, many first-time newsletter writers choose to send their first emails directly from their business computers using their company domain name and email address. What a big mistake.

Why is This Bad?

The majority of personal email accounts, especially those hosted by free services such as Gmail, Hotmail or Yahoo! refer to one of several internet SPAM blacklists to help them decide whether inbound mail should be delivered to the user's inbox or the junk mail folder. The email providers also send the blacklists feedback in the form of a list of SPAM hitrates. In other words, what email addresses are routinely sending email that recipients are marking as junk unsolicited mail and don't want to see.

For many people, the terms email blast and spam are synonymous. While many email blasts are indeed spam, there are a few simple guidelines to make sure that your legitimate messages get through.

First, only send to people who have opted in! The quickest way to get flagged as a spammer is to have a large number of recipients complain about you. Create an opt-in list through your website or when people sign up for your product. Building a list may be a slow process but it will pay off in the long run. Purchasing a list from a reputable list source can work at times, but even with a good list, you are likely to have a higher spam complaint rate than with a pure opt-in list.

Make your subject line clear and accurate. It is better to have someone choose not to open your message than it is for them to open it and log a complaint. If you have to trick them into opening, they probably don't want the product anyway. Avoid common spammer language like "you're a winner", "free", "open immediately" and anything that could be taken as x-rated. If your subject line sounds too good to be true, most people will avoid it. Keep it simple and concise.
