Here is an email: I will be on vacation from Monday the 19th through Monday the 26th (returning to the office on Tuesday the 27th). My cell phone and pager will not work either at sea or in the countries I will be visiting. I can be reached via Maritime Communications Network at (877)225-7447 - you will need to give my name and the name of the ship - Celebration. Since the rates are around $10 per minute, I don't plan to check my voicemail as often as usual but will call in when in port.
What is a potential subject line for this email?
