“Did you get the revised schedule I sent out last week?”
You are planning a business trip for you and several coworkers. You send an early schedule a month ago, but then you made a new schedule which you sent last week. You want to make sure that your coworkers saw the new schedule, so you ask this to one of them.
Did you get the revised schedule I sent out last week?
This is a general phrase that can be used with lots of different words:
I liked the guy you introduced me to at your party.
The computer I was using was pretty slow.
In written English or formal speech, it's considered correct to include "that":
Did you get the revised schedule that I sent out last week?
This means a document that has been changed and created as a new version. You can "revise" an essay, a price estimate, an email, a schedule, or other similar documents. You can also use the word "revise" to describe changing plans that are not actually written down:
We revised our lunch plans and decided to meet at 12:30 instead.
The changes that you make are called revisions.
When you add "out" to the verb "send", it suggests that you are sending it to more than one person:
We sent out our wedding invitations 6 months before the wedding.
Did you receive the revised schedule that I distributed on March 7th?
"Get" means "receive" in casual or informal business settings.
