It's super easy to use! Notifications come through every time someone sends me an e mail so I'm never late again! There isn't much you can say bad about this software but maybe it could be made better if there was multiple options that would create different rules instead of just one setting? But besides that everything has been great!! Easy to set up, quick turnaround time between changes.
Great support team behind product as well. No issues so far! We have been able to use this tool effectively against spam campaigns that we send out through our marketing channels.
