 LuxSci’s High Volume Outbound Email service now supports the optional use of VERP / Variable Envelope Return Path for simplified bounce message analysis.
Normally, when an email message is sent, but fails to reach its destination, a “bounce message” is sent back to the “Envelope Sender” (i.e. the “Return path” address, which may or may not be the same as the “From” address). These bounces inform senders of delivery issues and allow for the management and pruning of mailing lists. However, there is no uniformity in the format of these bounces messages. It is even sometimes the case that it is not possible to tell to whom the message was originally sent! This makes analysis of bounces both difficult (no standard format) and imperfect (can’t always tell).
Enter VERP – “Variable Envelope Return Path”
With this method of sending, the address to which bounces messages are sent (the Return Path) is customized for every recipient, so that it contains the failed address.

 In many ways, the Internet is still like the Wild Wild West. Email messages sent to you or from you can and do “go missing” for no apparent reason. This can happen no matter what email provider you use. So, what happened to these “AWOL” messages? How can you diagnose and solve the problem?

So, you’re minding your own business, going about your daily tasks, checking your email, and suddenly your INBOX is flooded with a series of non-delivery reports (aka NDRs or bounce messages). But wait just a minute, you didn’t send these. How did this happen? Did someone steal your email address? How is that possible?
