Hey [NAME]!
I wanted to reach out and see how you're doing. I've noticed you haven't been able to take on some of the recent projects that have come your way, and I wanted to check in to see if anything has shifted with your schedule or availability.
I completely understand that things change, whether it's other commitments, bandwidth, or just needing to adjust your workload. I want to make sure I have a clear sense of the team's availability going forward, so I'm reaching out to everyone to share or confirm everyone's availability.
