We've all received them, but are you sending them yourself? I am specifically talking about an email message signed by an executive but with a Yahoo.com, Hotmail.com or Gmail.com address in the signature.
When you have a website, you should really use the associated email addresses that contain your domain name. Not only does this market your brand - your site and you, but using your domain name in your email address is a silent salesman to drive traffic to your website for prospects, customers, and even clients. Once on your website they can learn more about your products and services. You would be absolutely amazed at how many times you will find email application notes as referrers in your website traffic logs.
Yes using some of these free email services is easy, but does not communicate the level of professionalism or the services that you may provide. If you feel that you really must use these generic email addresses, you may want to consider having your custom domain email forwarded to your catch all Yahoo.com, Hotmail.com or Gmail.com account.
When you are an entrepreneur, you have to take advantage of every edge, every avenue, and every free opportunity to promote your brand and your services. There is simply no better way to do this than to use your own domain name as your email account.
