Is it mandatory to verify my 123Greetings connect/Invitations account if I'm a 1st time user?

It is not mandatory to verify your 123greetings Connect account. However, we suggest you verify your email id as the username is common to both 123Greetings.com and 123Invitations.com and without  verifying you may not be able to get access to advanced features at 123Greetings.com.
