Q: Is it okay to have guests reply by email? And if you do an email RSVP, do you print it on the invite or a separate card?

A: Using email for RSVPs can be a great option on your wedding invitations—but just be sure it's not the only option! Add the following line to the RSVP: "If you prefer, you may reply by email to happycouple@rsvp.com." This is a great choice for an informal wedding or if the wedding is taking place on short notice. Emailed RSVPs are also a great choice for those looking to be green. Just be careful, as emails can be lost or caught in spam filters and addresses mistyped, leading to confusion. It's key to have a mailing address or phone number as your other RSVP option for guests who don't use email regularly, such as grandparents or others of an older generation. —Anna Post, The Emily Post Institute
