Mountain View, CA.,June 18, 2013—Sendmail, Inc., which simplifies business email complexity for Fortune 1000 enterprises, and CPP, Inc., an industry leader in research, training, and organizational development tools including the Myers-Briggs Type Indicator® (MBTI®) assessment, today issued an infographic with findings from its new Email Personalities Survey.

According to 43% of the survey respondents, of all the communication technologies in the workplace, email is the most likely to create resentment between senders and receivers. Texting also ranked high on the list of offenders at 32%.

While 92% agreed email is a valuable communication and collaboration tool, 64% reported having either sent or received an email that resulted in unintended anger or confusion. The reasons for this include: lack of replies (51%), too many “Reply Alls” (25%), messages that were confusing or vague (19%), and too much email in general (18%).

Using MBTI concepts, email senders and receivers can begin to address common issues in email communications, particularly related to reducing confusion, email frequency, and increasing relevancy in this still-abundant communication method.

“This is the reason CPP wanted to work with Sendmail to create this survey,” said Jennifer Overbo, Director of MBTI Product Strategy at CPP, Inc. “By being aware of your personality preferences and those of your colleagues, and adopting better email etiquette, you can tailor communications for more productive interactions in the workplace.”

Findings were mostly consistent across all age groups, except for 18 to 29 year-olds who are 13% less likely than 30 to 40 year-olds to be angered by email, 7% more annoyed by bad grammar than all other age groups, and 12% more likely to value faster replies. At 45%, this group also points to texting—not email—as the technology most likely to create friction in the workplace.

“Thirty years after our founder created the technology that helped make business email what it is today, people still struggle to craft messages that don’t create confusion or resentment,” said Sendmail Vice President of Marketing Barry Shurtz. “Proper email etiquette is key, but co-workers also need to consider the personality and preferences of those they’re emailing. This will help ensure messages are interpreted as intended.”

To avoid creating tension when emailing, CPP and Sendmail recommend combining “personality awareness” with proper email etiquette. For instance, those with a preference for Extraversion—who may send long and frequent emails—can try being more concise. And in general, even the busiest of emailers should acknowledge all emails with at least a quick reply. More tips are included in the infographic, which is available for download here.

More than 500 working professionals in the US, 18 years and over, participated in the Email Personalities Survey, conducted online during the month of March, 2013.
