Dealing with unwanted messages, especially when they come repeatedly with phrases like 'Go Away' or 'Return to Sender,' can be frustrating. From my personal experience, setting clear boundaries is essential in reducing the influx of these messages. One effective way I found is to create a consistent response routine. Using simple, firm replies such as "Go Away - done" helps signal that their messages are unwelcome. Over time, this can discourage further contacts. Additionally, utilizing automated filters or spam blockers on your messaging platform can drastically cut down on these unwelcome notifications. Another practical approach involves leveraging the 'Return to Sender' concept, especially useful in email or postal communications. Marking messages or items as such clearly communicates that they are unwanted and should not be sent again. It also helps in tracking and reporting persistent spam sources. While there is no magical fix, persistence and clear communication paired with technological tools make it easier to manage and eventually reduce unwanted messages. It's important to stay consistent and protect your mental space from unnecessary interruptions.
