We have the date, venue, dj, officiant, photographer, florist all booked. Our date isn't until fall 2018. Is there a time that's too soon to send out save the dates? Have people coming from out of state (Florida, Illinois, Arizona, Pennsylvania). Some are asking that I send something out as soon as possible so everyone can plan (lots of planners in the family). Is it tacky to send an email before the formal save the dates go out?
