I didn't approve my proof. Web site postcards are glossy printed postcards featuring a full color snapshot of your web site on the front and an optional customized marketing message on the back.
Most customers are surprised at how faithfully their postcards match their online image.
Because of differences in calibration of monitors, however, some printed colors may not exactly match the colors on a specific monitor. Many businesses send them to their mailing list to tell people they are online. Schools give them to students to tell parents about the new web site. You can hand them out at trade shows, send them to vendors and partners to drive them to work with you online, and announce enhancements to your site. Some people have even used them as Christmas or business cards.
