What about your readers' responses to your emails? This data will tell you fairly conclusively how often you should be emailing your list and how effective your email marketing programs perform.

Your readers' feedback is the best way for you to evaluate the effectiveness of your messages. Readers will let you know if your messages, offers, or promotions are beneficial. You will still hear the news about them if they aren't. So, do your best and do it well.

Once you feel you have reached a cadence that is beneficial for your readers and your business, you can start to improve the effectiveness of your email communications, also known as optimization.

Start by listing your goals for your email program. Are you trying to get a new business or increase brand awareness? Flash sales to clear excess inventory. Next, define success.

This could be as simple as making more money or as complex as achieving higher click-through rates. Or it could be as ambitious as turning your brand into an internationally recognized entity.

No matter what your campaign goal is, remember that it is your audience you are trying to win. Your audience-centric perspective will show your reader that you care about them and are willing to help.
