First
You need a mark to ask.
Whoever you send this to should be able to see who is asking, and that cannot be a name typed into a box. Asking with a mark means they get a question from somebody identified, not from a string.
Ask
What do you need to know?
What to ask for
Ask for the answer, not the document
Most things you need are a yes or a no, and those never move the underlying detail. Ask for a value only where you genuinely have to hold it, because they will see that you did.
Before you send
Ready
Send them this.
Nothing has reached them yet. They open it, see exactly this, and decide.
