Mail Add on Zoho Recruit and Zoho CRM

Mail Add on Zoho Recruit and Zoho CRM

I currently have a paid edition for Zoho Recruit in which I also pay for the mail add-on. I also use Zoho CRM, but the free edition. Do I have to pay for the mail add-on for Zoho CRM (even though I'm paying for the add-on in Zoho Recruit) to use the add on in Zoho CRM? If neither of these are options, how do I receive emails in the Zoho CRM system?
