A mail echo

A mail echo!

A mail echo is a type of email loop where an email is sent to a list of recipients, and each recipient responds to the email, causing the email to bounce back to the original sender. This can create a never-ending loop of emails, with each recipient receiving a copy of the original email, followed by a response from the sender, and so on.

Here's an example of how a mail echo might occur:

  1. John sends an email to a list of 10 colleagues, including Bob, Sarah, and Michael.
  2. Bob responds to the email, sending a reply to John.
  3. John receives Bob's response and sends a reply back to Bob.
  4. Sarah, who is also on the original list, sees John's response to Bob and decides to respond to John.
  5. John receives Sarah's response and sends a reply back to Sarah.
  6. Michael, who is also on the original list, sees John's response to Sarah and decides to respond to John.
  7. And so on...

As you can see, the email loop continues to grow, with each recipient responding to the previous response, creating a never-ending chain of emails.

Mail echoes can be frustrating and time-consuming, especially if they involve a large number of recipients. To avoid mail echoes, it's a good idea to use email filters or moderation tools to prevent responses from being sent back to the original sender.
