Get a handle on your mass emails

A switchman directs trains through a train yards, sending them in the proper direction. The job requires skill and training to evaluate and move traffic safely through the yard. Like a switchman, we worked for years to educate our software to correctly read an email and understand the reason it was returned. Most email software only tells you whether an email was received, not why. Our software uses the established rules of email to understand the reason it was sent back. Once we understand the reason, we allow you to take the appropriate action.”

You Have Options

For your returned email processing you have two options. Both options will use the ResponseMaster software so that you receive the best returned email processing solution on the market.
