The books were personalised by using each recipient's name as the author of their specific book. In addition, the recipient's name was printed on the spine, and the recipient's address was included as part of the copy on the back cover. Inside the book, meanwhile, a personalised letter provided details of the life on offer at the Navy.
The camaign looks to recruit systems specialists, a traditionally 'tough sell', according to Saatchis chief executive officer Simone Bartley.
"It's a difficult role to recruit for, because it's probably not the sexiest," said Bartley.
A 'lift-letter' in the form of a bookmark was also included as a call-to-action, providing details of a half-day naval base tour. Recipients could respond by SMS or post. Inside the book, the rest of the pages are blank, and can be used as a personal journal.
