Professionally ignore people with style.

Thank you for your email. I will be ignoring it on a delay. I am away from the office for a general and none-of-your-business absence. Budget drama, calendar gymnastics, and status updates may proceed without me. I will respond when I return, which is earlier than some expectations deserve. If the issue cannot wait, contact the on-call lead or team alias. Thank you for your measured response to my unavailability.
