Mass emailing can work especially if you are using your own database to send to. If you opt to buy lists of email address from third parties you have to be aware that you may get the results that you had hoped for and can end up upsetting people by contacting them when they have not agreed for you to do so.

Although many companies that sell these lists stipulate that all the addresses are opted in, this is very often not the case. Also the data contacted in a mass email marketing list can often be out of date and not relevant to the business you are promoting.

You have to be careful how you send out these emails if you do decide to give it a try, as many server owners will not allow mass emailing as it not only uses up all their server bandwidth but can also cause the IP of the server to be blocked. If you are not sure on the limits of emails you can send through your server in any one time perior then check with your service provider.
