Let people/visitors contact you from your website
There are three ways to let people that visit your site contact you. Here they are in increasing complexity.
An email address in the site's footer, header, and/or other page. I.e. "For questions/comments, contact [email protected]" This is often the best bet.
An email form that people can fill out on the site. It includes space for 1. a return address, 2. a subject and 3. a body message. Emails are delivered privately to your "[email protected]" inbox just like any other email would be.
A comments form that people can fill out on the site. It includes space for 1. a return address and 2. a body message. Comments appear publicly on the site for anyone to read, and you can moderate those comments (edit, delete).
Which is your preference?
