When someone inquires about buying a domain name listed for sale via Embrace.com, they will read my response and the accompanying email signature. You’ll notice a few things I think are important for an informative signature to include.
In addition to including a link to the website’s homepage, I include a link to my LinkedIn profile. This serves two purposes. For one thing, the prospective buyer can see that I am a real person with experience related to domain names. This might make them more comfortable doing business with my company. In addition, if they click through to my profile, I may be able to see more information about them, making me more comfortable.
