Measuring the value of an email address to your business is more than measuring open and clickthrough rates. Where offers are made within emails, that are likely to lead to a purchase or sale, real value (in terms of return on investment and revenue per email) can be measured and compared directly with other methods of promoting to your customers.
Having your customers' email addresses can provide you with two key benefits. Firstly, it can help you promote your products in a way that allows you to accurately measure the success of a campaign in real dollar terms Secondly, it provides a really low cost method of distributing product information and catalogues to your customers.
