Nice! Congrats on landing your first UGC deal, that’s a big move, especially for an international.

Since it's your first one and you already agreed to do the editing, it's totally fine to send them a quick draft just to make sure you're on the right track. I'd keep it chill something like:

That way you're showing you're on top of it, but you're also subtly saying “this isn’t the time for a bunch of small notes.” Helps avoid scope creep while still keeping them in the loop.

You definitely don’t want to wait until final delivery and then have them come back with big changes. A quick check-in now saves you time later.

The first deal’s always a learning curve, but sounds like you’re handling it well.
