Inevitably, someone will need to contact someone in charge of official business of the Web site. This probably will not be a technical matter for the Web master. It will be a sales question or complaint, a product inquiry, a request for investor materials. It is essential that the corporate site have not one but multiple e-mail sources as points of contact for each of these questions. Telephone numbers will not do.
Email is critical for corporate credibility.
Since the questioner has visited the site via the Web, to switch gears and require a different method of communications will un-inspire confidence. It's essential for today's corporate Web site to have and to post a Privacy Policy. If other policies are in effect, such as disclosures for investing in stocks or purchasing goods and services, it's critical to have these as well. Policies must be clearly posted with links with the homepage for corporate credibility, and the policies themselves must be foolproof. Hack me once, the man said, and shame on you.
