How to send an email to a 2nd email address associated with Lead or Account

Within CRM, I have a primary contact, or Lead.  There is a second person closely related to the Lead that I'd like to send an email to, who has a different email address..  Is there a way to do this?  Perhaps connecting the Lead module to another module?  As it relates to the Lead, I'd like to set up a task, or automated task even, to send an email to this second person.  Recurring emails actually, once per month.

Perhaps this can be set up outside of CRM?
