Spark Premium for K-12 - can I resend the new account email?

Is there a way to have our student Spark account information email to be resent?  When I set up our Spark for K-12 accounts, the system sent an email to student users.  This happened before school started as it was an auto-send, so many of the students deleted it not know what it was.  We'd like to get started with our Spark accounts, but need that email to go out again so users can use it to get their accounts started.
