"Never use a 'do not reply' email address" is something that we seem to have been saying for years (because we have). Today we are repeating it, hot on the heels of a real-life example, a retail mini-saga that unfolded for us with a large, well-known online retailer. The saga could have been easily downgraded to a minor glitch, had it not been for the fact that we kept receiving what seemed to be quite urgent, even strident, emails, all from a "do not reply" email address, and with no other way to respond to the email (no alternate email address, no phone number, zip, zero, zilch). It serves as a good reminder that not only can "do not reply" email addresses be incredibly frustrating (especially if some sort of alternate communication option is not provided), but they can also affect your email deliverability, especially when "no reply" email addresses are in fact non-existent email addresses.
