You sent a paragraph about the band, a link the mail client turned into plain text, and "we'd love to play sometime." The booker has forty of those this week. Sometime is not a night. A night is a calendar cell they can say yes or no to.
A venue is a room with a door and a clock. The booker can hold a cell if you name it, name how long you play, and do not invent a draw you cannot fill.
Ask for a night
"Can we have Saturday June 14, 45-minute set, 9:30 start, we can bring an opener, yes or no by Wednesday." That is a decision. "Any openings in June" is a hunt you are asking them to do.
One fallback date is allowed if you write it as a closed pair. Six dates is a spreadsheet. They will not build it for you.
Give the facts that are checkable: city you are based in, last room you played and about how many people were in it, set length, whether you need backline, whether this is a single night or you are asking for a hold on a tour. A tour hold is a different letter. Do not hide four cities inside one Saturday.
Your lean: "June 14 is the one we can fill. If that is gone we can do the 21st, and I need the no by Wednesday so we stop holding the opener."
They are not on your stack
The booker is not connecting an assistant for incoming bands. Write anyway. The mail is how they get it. They reply from the mail or the page. You approve every word. The assistant does not book rooms as the band.
Music does not travel as a file here. Name the page or the service where the songs already are. They will go find it if the date is possible. A note full of addresses and no date still fails the swap test: it could have gone to any room.
Do not put a private nickname in the package. They are the room, or they are the name on the last reply.
If you write in Claude and a bandmate writes in ChatGPT, the venue sees one briefing. That is the point.
Follow up once, with a fact
Following up without nagging means the second message carries something the first did not. "The opener confirmed" is a fact. "Just bumping this" is not.
If the second also goes unanswered, that is the answer. Write the next room.
Set a default. "If I do not hear by Wednesday, I will take the 21st at the other room and write you once that is settled." Do not show up on the 14th on a silence.
What this is not
It is not a press kit. It is not a merch conversation. Those wait until someone has said the night exists.
It is not a blast to every booker in town with the name swapped. One room, one night. The test is whether the sentence would be false if you sent it next door. If it would still be true, keep cutting.
If your assistant already has the last booking note, let it draft this one. You read the date. Then a booker can answer between load-ins.
