Tell a friend - importing contacts - UI(X) design
===

I am designing a tell a friend tool for our website and I am stuck.

The script is allowing the user to import his own contacts and to mass send an invitation.
For some (SPAM and quota) reasons we do allow sending max of 30 invitation per hour.


Adding contacts one by one is not a problem, we let user know, that more than 30 contacts are not permitted....

but importing contacts is tricky... most users do have 100+, some even 1.000+ contacts. How do I present this? Do I import only first 30 contacts? the problem is I do have just email and a name for a contact, so the only filter I can offer a user is by first letter

![How it looks like now][1]
