“Our company had a huge problem due to the large number of returned mail. We found out about “AES System” and decided to buy it to see if this software could help us solve this situation. It’s been more than 4 years now, and we’ve seen how the problem of returned mail has been dramatically reduced. This Postal address correction software is very user friendly.”

“AES System had a great integration system was able to integrated all my products using AES simple API. I was a bit worried about making a change and seeing if a new system will work, but it wasn’t a problem at all. I love using AES System CASS engine when I’m processing all my data to keep up to date.”
