I won't go into all the thoughts that run through my mind when I see someone with an email address ending in @aol.com. However, I must chime in on business emails.
It's simple, if you have a business you have to have a website. If you have a website you have to have a domain. Purchasing this domain entitles you to an email address of the same name. Use it. If you have not set this up you aren't in business yet. Be patient.
On average I have seen contacts from 5-10 staffing agencies every week for the last several years. This has led to an extensive list of healthcare staffing
agencies I've worked with. Of all of these contacts I still see at least 2-3 agencies per month with an email such as 'firstname.lastname@example.org' or simply, 'email@example.com'. (These are fictional examples)
Whenever I see an email address like this I automatically think – how can I take you seriously if you don't realize you need a website with a domain and a proper email before you start making business contacts? What else are you overlooking? Further, how is it I can seriously help represent you as a business partner?
The worst is when these same companies actually send information requests. I personally won't send any business information electronically unless it's to a corporate email address. How am I to trust that you're not a competitor? You may not be but your email certainly isn't helping me to know that.
The summary – as a business owner, one of the first things you should do is register a domain and get your email account set up. You can even do this before you have your actual website built. There's no reason to wait.
Please, use a corporate email address. It's the least you can do.
