Note that each membership requires a unique email address. If a family/household has multiple memberships and wishes to have all emails sent to one email address, the email address that is to receive the emails can be used for subsequent household memberships by adding '+[name]' to the original email address. For instance:
A household with memberships for John Pyro and Sally Pyro wishing to have email for both memberships go to the Johnpyro@email.com email address would set up John's membership with 'Johnpyro@email.com' and Sally's membership as 'Johnpyroemail@example.com'. In this case, both emails will go to the Johnpyro@email.com address. We recommend using truely unique email addresses as not all mail servers recognize this '+name' protocol.
