Defining Standard E-mail Open, Click-Thru and Unsubscribe Metrics
February 7, 2012
The most common question I get from clients when discussing e-mail marketing is “What are the standard open and click rates they need to get to be successful?” My standard answer is of course 100%. I quickly explain this number only applies if you’ve successfully built a campaign that clearly identifies prospects that have the need, budget and are ready to buy when the e-mail hits their inbox. In this case, anything less than 100% response rate should be viewed as failure.
For most organizations, having such a clearly defined target audience is not practical. As a result, determining a satisfactory response rate requires a better understanding of your program objectives, what you are attempting to measure and the quality of your list. All three elements will play an important role in determining your target e-mail response rate and measurement criteria.
For example, if your program objectives are to increase awareness of your company, product or solution, then measuring the combination of open rates will give you a good indication of the quality of your program and if your messages are being received. You may also want to include a metric focused on audience growth such as the number of e-mails sent as compared to the bounce rate.
If on the other hand your objective is lead generation or even list segmentation, click-thru rates are going to be much more important. In these types of programs, the number of e-mails sent could actually decrease as you learn more about your target audience and emails become more focused on the specific needs of the individual recipient. In these instances, maintaining your delivery rates will require more, unique e-mails sent in smaller batches. Your goal should be to appeal to the individual and, as a result, achieve a higher click-thru rate.
Regardless of your objective, two numbers need to be consistently measured and acted upon to determine the success of your email program. The first is your unsubscribe rate, or the number of people who request to be removed from your email communications. Clearly, you want this number to be a low as possible from email to email. The second is your click-thru rate, or the number of people that click on a link within your email. This number represents active interest in your email message. Each click should results some activity to further profile or qualify the individual’s buying state to determine if there is an immediate sales opportunity.
This same lesson, although with slightly less dangerous consequences applies to your marketing planning. Unless you’re able to apply real world knowledge to the solution, there’s inherently more risk that your programs will fail to achieve your desired lead generation goals. Similarly, without the pre-requisite experience, the odds are significantly higher that you’ll fail to recognize opportunities that could deliver better results than the programs would that you initially planned.
