Question: Does anyone know of good software for surveys?

Answer: DotNetNuke has a survey module.

The DNN survey module is free, but must be installed and configured.

Let me know if you want me to add the DNN Survey module to your website.

Since you have multiple domain names, you could use one of them for a different website with the survey module, say more of working website, while you leave your other as a marketing website.

You should be sending out a newsletter and building an email list. I really like www.Aweber.com. They do not have surveys, but you do not need them, because you can a survey on your own website. They do have autoresponders which send out a series of emails.

Constant Contact is another email marketing service and they do have surveys, but not autoresponders.
