If you are a startup or a small company, bootstrapping marketing efforts for fast growth on a shoestring budget is totally understandable. But think about this: will cutting corners reach your potential customers effectively? This includes using free email accounts instead of paying for professional business email.
General and free email accounts such as Gmail, Hotmail and Yahoo mail are unprofessional in the eyes of clients. These free email addresses detract from the value you want to offer your customers, leaving them with a bad impression towards your business. Hence, having a company custom email address is important to build trust and confidence with your clients.
