Any form of marketing can be used to enhance your email list. If your business spends time and money managing media campaigns, you should leverage these endeavors to help collect additional addresses.

In The Constant Contact Guide to Email Marketing, Eric Groves, the Vice President of Global Marketing Development with Constant Contact, explains how to make your marketing campaigns work together:

Do you participate in the Greater Kansas City Home Show, the Kansas City Auto Show, or the Overland Park B2B Expo? If so, are you doing everything you can to generate new customers from these events?

Frequently, businesses do not take maximum advantage of the prospects they meet at tradeshows and other events. One of the things you can do to ensure you get the most out of these efforts is to add all the appropriate new contacts to your email marketing list. Be careful, however, to add only the appropriate contacts. Some people might not be good prospects--or they might not be prospects at all!

Personal points-of contact are great places to collect email addresses for your mailing list. Whether you have a retail shop or a professional office, if customers come to you, it's a golden opportunity.

Just as with every other form of customer contact, you should have a well-defined process for collecting email addresses from those who visit your business.

From Kansas City, Missouri to Kansas City, Kansas, there are networking events all over the Metro. What are you doing to ensure you collect the maximum number of email addresses from each event you attend?

Just as with inbound phone calls, you should have a email marketing strategy designed just for business networking.

Customers contact your business in a number of different ways. Whether they reach out to you via traditional land lines, mobile phones, or inbound email messages, you should have a definite plan for adding email addresses to your list from each of these conduits.

In his new book, The Constant Contact Guide to Email Marketing, Eric Groves of Constant Contact suggests specific approaches for each of these situations.
