Imagine you are meeting a prospective client about a new business development project. The meeting goes fantastic and you realize you are about to close the deal with this client.
(It’s all about professionalism so far..)
The client asks you for your email address so he can send you the deal-closing contract.
You gotta walk the talk if you mean business…
While both are valid email addresses, they would bring about completely different responses. When you are trying to close a deal and talk money, a gmail.com just doesn’t cut it.
A custom domain email address might actually land you that business.
