If I receive an email from someone with an AOL email address my first reaction is that they are older and/or old-school. A Gmail email address is the newest iteration of a bad email address for business purposes.
Let me explain. If you have a business such as the ABC plumbing company, you should spend $15 a year and register the domain name ABCPlumbingCompany.com. Via this domain, you can set up an email address such as email@example.com or firstname.lastname@example.org. For years I have worked with GoDaddy for web hosting and email addresses. If you own a domain name, use an email address via that domain name to promote yourself and your business. Not AOL or Gmail.
It is my opinion that this type of email address makes you look more professional and promotes you and your business.
If you don’t have a website you should. A one-page website is an easy and inexpensive way to promote your business. It is your brochure. It is your identity. It is the cheapest marketing material you will ever produce.
