Anyone know of a good website for engagement email inviatations?

I need help finding a good website to send engagment invitations by email to my finaces family in Oregon. I am not a fan of sending invitations by email but it is an informal party and we need to do this quick.

Any ideas?

evite is good, because the RSVPs are right there..and they have a lot of nice backgrounds

if you would rather keep the mailing list private, i would suggest making a nice graphic and sending that through email....
