Sending one message to everyone saves time, but not all readers care about the same things. Some people may be new and need simple explanations. Others may already know your brand and want updates or offers. When everyone receives the same message, many might ignore it because it does not meet their needs. Creating different versions does not have to be complex. Even small changes like adjusting the greeting, the examples, or the main point can make each group feel understood. This often leads to better engagement because the message feels more relevant. Do you think email groups should be simple or more detailed?
