The average email account receives only 2 emails each day, said Massoud Janekeh, a partner at Integrum. Research by the firm on the trading floors of three investment banks showed that traders and support staff received a daily average of 40 emails.
Janekeh said at least 6 of these are usually spam. Employers filter out many spam emails, but some still get through. Banks make things worse by sending pointless emails about company events, which are best left to the company intranet, he said.
He said that one reason traders liked to use Bloomberg to send messages (which were not included in the survey) was that they could avoid spam. For this reason, closed messaging systems could become more important in the future.
