Show App Value with Regular Results Emails

One of the tactics we employed early on was taking a page out of salesforce.com’s playbook by sending an opt-in daily email to users of our app highlighting results. What I mean is users get spoon feed an email report detailing all the visitors and prospects that have been recently active. This type of feature has several benefits:

• Removes friction with more passive users so that they see value from the product on a regular basis
• Makes it easy for the stakeholder to forward the results to his or her boss
• Helps keep the product top-of-mind with users while encouraging them to use the app more frequently by clicking through to see more details
• Sets the tone for many of our users to be one of the first emails they look at each day because the data is so valuable

My recommendation is for entrepreneurs to provide daily or weekly metrics to their customers to help drive product value and customer satisfaction.
