A survey by a office products company in UK found that kisses on emails to clients are disliked by 66 per cent people while 44 per cent said they didn't approve of smiley faces in mails.
Two-thirds of people said that they regard simple mistakes in an email as 'shoddy' and would 'have no faith' in the sender, the Daily Mail reported.
Fifty-eight per cent of office workers said they felt irritated and wouldn't do business with people who took annual leave and failed to leave any 'Out of Office' message at all as it showed a lack of professionalism and care.
Rude or abrupt 'Out of Office' message was also one of the biggest workplace irritations for 46 per cent of UK businessmen and women.
Terms of endearment to clients, such as 'honey' or 'dear' also do not make a good impression, according to 54 per cent people, the report by Staples said.
Abbreviations such as 'OMG'(50 per cent), cheesy lines such as 'Happy Friday' (28 per cent) and asking clients about plans for the weekend (17 per cent) were also a big no.
