Ask the missing questions in a client brief
A brief that leaves out the approver, the audience, or the file format can cost you a revision round. Paste the brief and ask for the questions you would need answered to scope the work.
What to check in the answer
Go through each question and check whether the brief or an earlier email already answers it. Cut duplicates before anything goes out. Replace loose questions with specific ones. "What is your timeline?" is weaker than asking for a launch date and a date for first-draft review. Make sure each question asks for one fact the client can answer in a sentence.
What to do next
Send the questions in one message. When the client replies, paste the answers back in and ask whether any new gaps show up. Keep the whole exchange in writing so the scope is documented before you start.
