When it comes to marketing, it can be hard to know what works and what doesn’t. One option that you have is to do something called mass mailing. This is where you send out an email to a large group of people to advertise a product, service or your company in general.

Some businesses send out mailings to an existing database they have built up from previous, current or prospective clients and other businesses buy in lists from a third party. When doing any mass mailout you need to ensure that the people you are sending it to have opted in to receive information from you as it is illegal to send to someone that hasn’t. All emails should have an unsubscribe link on to allow people to remove themselves from the list should they wish to do so.

Buying lists of data can be dangerous as you do not know that they have opted in and more often than not you will find a number of the email addresses no longer exist or that you are contacting people that have no interest in your company and the products or services you sell.
