The best part of having vaultatic as our archive server was how simple it made sending emails to archives for clients! It's easy enought even an intern could use without too much hassle (or training). I dislike not being able to do more with my account than just send archived mail from one domain or another - but maybe this will change in future updates? We're using them primarily because we have multiple domains which require separate accounts so they can be set up individually rather then managing several different servers ourselves atm. Saves us time by automating all client communication through their system instead of logging into each individual service manually every day/week etc.. Also makes things easier when contacting past customers who were previously managed via these services since everything has been put onto 1 centralised place now :) Highly recommend if your looking for something cheap yet efficient way to handle large amounts of.
