Once you have a show confirmed you should send one final email that includes all of the necessary details. This acts like a contract. Most venues with capacities under 600 don't typically work with contracts - especially when booking directly with the artist. Even if they do work with contracts, it takes way too long to send one over, have them sign it, send it back and confirm everything. Most venue bookers won't take the time to do this. Just send them an email that looks something like this. Fill in all the information that you are certain of (what had been discussed in previous correspondences) and highlight the areas they need to fill in.
