I usually like to keep recruiting emails separate from personal emails. But the choice is completely up to you. Some people like to use only one main email account for both personal and recruiting emails. The advantage of doing this is that you won't have another email account to worry about. You'll know that you are getting every single email because you only have one email account. The disadvantage is that if your email account domain name at the end - that is what comes after the @ sign - does not match your company name, then it may not be desirable. For example, if you use YourName@aol.com or YourName@Yahoo.com as opposed to using a more professional sounding account like: YourName@CompanyName.com.
I feel that there is no advantage to you whatsoever if you have a professional email account but rarely access it. I've heard of recruiters who have a professional account, but only check emails on there about once every few weeks. That is not a good idea if you want to promptly answer emails. So, I would use the account that you feel most comfortable using and that you know you will look at on a regular basis.
