Short and simple
When to use: Use it during a brief crunch where you still check email but cannot respond at your usual speed.
Message
Thank you for your email. I am currently in a busy period with very limited availability, so my replies will be slower than usual. I am checking messages briefly once a day and will get back to you within reply window. I appreciate your patience while I stay focused on priority work and keep everything moving.
Shorter version
Thanks for reaching out. My availability is limited right now, and I will reply within reply window. Thank you for bearing with me during a busy stretch.
Personalize
- Name the busy period plainly so senders understand this is temporary and not the norm.
- Keep the reply window realistic so you can beat it rather than quietly miss it.
