Your Invitation and Save the Date are the first look at your special day, so make sure your stationary (print or electronic) accurately reflect the style of your wedding.
The best pieces of advise that we could offer: 1. Make sure your Save the Date and/or Invitation look good in print and in electronic format. 2. Electronic invite or not, be sure to take the same care and concern that you would with a printed invite. 3. Confirm that you still have both current email and physical addresses. 4. Be aware of SPAM filters that could hinder your invite from being delivered to a recipients inbox.
