Send a "welcome email" on new membership.

We are a seasonal club.  Each year members have to purchase a membership.

I'd like to send an automatic email out when a member purchases a membership.   Things that would be included in this email.  Generic welcome statement, a link to our Membership rules for the current season, information that is important on a yearly basis, like the gate lock code.  We change this yearly.

Currently I'm doing this manually, and it's very time intensive.
