Hello! I am concerned that our RSVPs are not going to come back to us - the invitation set that we purchased uses 4 bar envelopes for the RSVP cards but these are 130x90 mm which is below the minimum envelope size for Canada Post! (the minimum is 140x90 mm). Why on earth would Canada Post make a minimum envelope size that is non-standard? And why would my invitation set come with envelopes that are too small to mail? I bought the kit from a Canadian company too.
Does anyone have any experience with their RSVPs not coming back because they were too small?
