Yep. Basically you need to respect their time, and not ask them to duplicate the work you’ve already done. This is especially important for executives, but works well on anyone… if you really need someone to do a thing or answer a question, make it easy for them to focus on completing your ask.

Address the email to one person who you need action from.

Tell them succinctly:

Why is this important? What do you need from them right now?

After that, preemptively provide the answers to any followup questions they might ask - give them further context so they don’t have to dig for it. Don’t ask them to read a whole email string below if you can summarize it.
