We sent out our invites and we hear that many people will not RSVP one way or the other. The reply cards were stamped, have a due date of May 1st and there is NOT an option to RSVP via email or online (my dad thought this was less traditional and tacky).
I am wondering what suggestions there are for how to get ahold of the people who do not RSVP. We are having seating assignments so it is important we get an accurate name/head count. I though a simple email a few weeks before the wedding might be a polite way to say "hey I hope your invite arrived to you...blah blah....will you be able to attend?" Thoughts? Also, what to do about those who I do not have an email address for?
