It works like a charm

The only problem is that people can exploit the subscribe widget to send random subscriptions to people. There is no captcha on the widget, people can use the same IP address to register email addresses in succession, and emails are sent to unverified email addresses.

Because of this my account got blacklisted by Verizon. I had to remove all the subscribe2 widgets and forms from all my sites before the server would reinstate my service. One of my domains was offline for three days because of this.

All that being said, the other features are awesome. After I removed all the widgets, and no longer use this program for subscriptions, it sends emails as it says it will. Very nice!
