Be timely and create a sense of urgency: Technically, invitations should be mailed 6ξ weeks prior to a wedding. In these busy times 10 weeks has become the norm. However, more than that is too early and can backfire. Instead of making sure people respond promptly, this tactic actually causes most people to put the invitation on the "to_do later" list. Also be careful not to confuse your need for deadlines on the room blocks with the final head count for the caterer. You don't need an official head count until about a month before the wedding for the caterer, seating chart and rentals. It is your guests' responsibility to make travel arrangements and hotel accommodations, so try not to stress too much about that in terms of timing for your replies.
Don't lick one hundred envelopes: The safest way to seal your invitations is to use a glue stick. If you use a water sponge, you risk getting important cards wet and wiping the adhesive away. We provide glue sticks to our clients so there are no accidents a la Seinfeld or paper_cut tongues. Don't lick __ use a glue stick!
