"You are a despicable bottom feeding wretched disgrace of a person" This was the email sent to a prospective bride by New York catering company Sweetery in November 2016. It hit all the headlines and went viral on social media. Google Sweetery and guess what you find?

The worst mistake you can make is to think you are having a conversation when you email someone. In your head it sounds like one thing, on paper it is something entirely different. Emails can be painful, are always visible and can quickly go viral. 

Durham graduate Oliver Alcock spent his last day at a leading accountancy firm writing an excoriating email about his boredom at work. It went viral and has been published in full on various media. 

So for top lawyers to go head to head on email is not a good idea. The story has already gone viral and the content will have an adverse effect on the reputation of the firm. As it is a law firm it is a double whammy because it is often law firms who are asked to help with damage limitation caused by inadvertent emails.

If you want to negotiate, have a conflict, disagree do it face to face or on the phone or don't do it at all.  It could come back to haunt you for ever and ever.
