CRM Recruit and Mail

CRM Recruit and Mail

I have purchased ZRecruit licence and use the mail function however I am using ZCRM free format but I need to be able to use the mail over both the applications, I will never hit 250 bulk emails a day in the Recruit nor in the ZCRM due to the nature of my business and market. Is there anyway I can utilise the mail app I am paying for across both??
