The interface is super simple. There are no instructions but it's relatively easy to figure out how to set it up.

The software initially sent emails from my email address but as another person. I felt uncomfortable with this and changed the signature in their settings to reflect my company. I am happy that they provided that option. It would be good if that was the default setting.

The software worked great for a couple of days but hasn't sent any emails in about 4 days. I am not sure why it stopped. A notification from the company and an explanation will help reduce the guesswork.

Overall it's a good product with great potential.
