In 2020, there are an estimated 306.4 billion emails sent every day.
So here is the question: Are the emails you send worth your time or a waste of time? Do they uplift others or bring them down? Do they make the world a better place, worse place or neither?
Another thought: Hashem reads them ALL! That is just a drop in the ocean of His abilities.
The upshot of that is that part of our judgement on judgement day is on our emails.
Another judgement will be on our browsing history. Would be comfortable if your browsing history were made public? Well, it is not forgotten. You can delete your history from your computer but not from the Ribbono Shel Olam. So think about that before you click.
