Here is my advice to companies sending these statistics review emails. Change your strategy to only send statistic reviews when people have had action on their profiles. This doesn’t mean you can’t send out other emails of interest. Manta for instance sends out some valuable tips. If you asked those companies if they think sending emails that make them look bad is a good idea they would look at you like you have two heads. Yet, this is what they do, again and again.
Bottom Line: When you are trying to build your brand, sending emails to users is not a bad idea. However, sending emails that tell people you are basically irrelevant, is not smart.
