When to use this email
A customer emails support outside your working hours
You want every message acknowledged instantly, before an agent picks it up
Your reply times vary and you want to set expectations up front
Tips for making it yours
State a real response window, not "as soon as possible"
List your support hours so off-hours senders know why it's quiet
Link the help center so simple questions get solved without waiting
Keep the tone human. It's automated, but it shouldn't read like a robot
