iContact -- recommended autoresponder

Autoresponder is very import for IPC business. However, if you think aweber is too expensive, then iContact is your best choice.
Actually it is as powerful as aweber, but it starts with $9.95 per month.
If you are using the pop-up page in the IPC website, then you still should use aweber.
However, the IPC website is definitely a good landing page.
You should use a squeeze page.
So you should find a squeeze page template, edit it and put the web form code generated by the autoresponder, and then drive traffic to your squeeze page rather than IPC website.
People must fill the email to read more information about your offer.
You can drive a 14 days free trial of iContact. They provide detailed trainings, so you won't have any problem.
