It contained the phrase "me love you long time".
The phrase is from Stanley Kubrick's 1987 film Full Metal Jacket, and was uttered by a Vietnamese prostitute as she propositioned an American soldier.
It is now widely considered to be offensive to people of Asian descent.

It received an outpour of angry comments labelling the email "racist" and "sexist".
"I'd report them. That's straight up racist," one Facebook user wrote, while another added: "This company has disgusting behaviour."
"This is highly unprofessional and unwarranted," another posted.
Initially, a friend of Cheung reached out to the company on her behalf to request an apology.
However, the situation then seemed to take a nastier turn when the unnamed friend allegedly received the following response from Haugh.
In the message, Haugh said he had "bigger problems" to deal with and appeared to threaten Cheung and her friend with legal action.
" β¦ with all due respect, I am focused on bigger problems than you friend being offended by a movie quote. Sorry, but just don't have time for this. Best of luck to you! You may want to Google libel laws before your crew posts things publicly. Our attorneys are on call β¦" a screenshot of the message posted on Facebook reads.

In a Facebook post, Cheung said McMahon had called her to apologise and "explain that the quote he used regarding me was from a movie".
But she said it was still inexcusable.
"Regardless if it was from a movie, it doesn't justify that this phrase has been used to demean Asian women for decades and that this phrase was emailed from someone's work email to a co-worker in regards to a potential employee, who happened to be an Asian American female," she wrote.
McMahon apologised again in an interview with USA TODAY.
"This was an isolated incident that will not happen again and my sincerest apologies go out to Connie and anyone else who was offended by this statement," he told the publication.
"It was intended for my business partner of over a decade who was also my college roommate.
"This does not excuse or justify anything. However, imagine if everyone had every inappropriate comment or poor joke that was typed, texted or spoken available for the public to see. It is a reminder for all of us that we should communicate with anyone as if everyone was listening."
Hughes also apologised, and said the email was "unacceptable".
Cheung is reportedly still job hunting.
