Have in the past worked as Customer Service Representative at an outsourcing top notch company for an international business, work profile required daily chat or email based interaction with international clients. Received 99 percent satisfaction feedback from customers in first month of interaction, and a top performer status. I believe even though email or chat interactions involve just words, one needs to make sure even the words are expressed so as to align with the person's interest level, so that emotions expressed are understood well.
