A tiny punctuation mark is sparking a big workplace conversation. Researchers from Penn State University and the University of Southern California have found that exclamation points in emails make the sender seem warmer and more enthusiastic, all without hurting how competent they appear. The findings could change the way millions of workers think about tone every time they hit send.
What the Research Revealed
4 The study, titled “Nice to meet you.(!) Gendered Norms in Punctuation Usage,” was published in the Journal of Experimental Social Psychology. 4 The researchers set out to evaluate whether exclamation points signal gender associations, how men and women perceive their use, and how exclamatory punctuation affects social perception. 1 The team from Smeal College of Business at Penn State and USC report that exclamation point use is widely read as feminine and shapes impressions of warmth, enthusiasm, power, and analytical thinking, without evidence that effects differ by communicator gender.
Here are the key takeaways from the five-part study:
- 4 Women were more inclined than men to prefer exclamatory messages.
- 4 Both genders anticipated that using exclamations would generate warmer impressions but also feared negative judgments regarding their competence and analytical abilities.
- 1 Exclamation points are widely perceived as feminine and signal warmth and enthusiasm, but reduce impressions of power and analytical thinking, without affecting perceived competence.
- 1 These effects occur regardless of the sender’s gender.
The bottom line: your fear that an exclamation point will make you seem less capable is not supported by the data.

Why Women Worry More About Punctuation
2 The research found that women are more likely to use exclamations and also spend more time worrying about their implications, fearing they may seem less competent. That worry, the researchers say, creates a real cognitive burden during everyday email exchanges. 4 Over the studies, it became evident that women frequently used exclamation points across various platforms, whether in emails or texts. They reported feeling greater pressure to manage their exclamation use, reflecting on how their tone might be perceived in terms of warmth versus professionalism.
This is not a new pattern. 13A 2006 study analyzed 200 exclamation marks in online discussion groups for library and information science professionals. The results showed that 73 percent of all the exclamation marks were made by females, while only 27 percent were made by males.
Psychotherapist Kassondra Glenn has explained this gap in simple terms. 13Women and female socialized people tend to be raised to believe that it is their role to be accommodating to others. The use of exclamation points can be representative of people-pleasing patterns, calming the situation by conveying to another that they are not angry and willing to compromise.
How Email Strips Away Human Connection
Email removes all the cues we rely on when speaking face to face. There is no tone of voice. No smile. No hand gesture to soften a direct request.
15 Email, like most of our digital communications, suffers from the fact that it doesn’t benefit from the kind of non-verbal cues we rely on to get our point across when we’re speaking in person, such as tone of voice, facial expressions, and body language. That is exactly why a period at the end of “Thanks.” can feel cold, while “Thanks!” can feel friendly. 32 Research shows that 90% of employees blame workplace misunderstandings on communication started via email, because it is difficult to express non-verbal tone in text. In 2026, with hybrid and remote work still growing, that problem is not going away. 29 Tone has weight without voice or facial emotions. A brief communication may come across as direct to one person and impolite to another. The goal of email etiquette in 2026 is to lighten tone without sacrificing clarity.
A single exclamation point can bridge that gap between sounding robotic and sounding human.
What This Means for Managers and HR Teams
For team leaders, the study sends a clear message. Tone markers like exclamation points can help build trust across teams. If enthusiasm reads as friendly and does not erode credibility, managers should feel comfortable modeling balanced use in updates, check-ins, and feedback.
1 Messages that aim for warmth may benefit from exclamations, while situations that call for power signaling or analytical tone may favor standard punctuation.
For HR professionals and recruiters, there is a deeper lesson here. Some hiring managers read punctuation style as a personality tell. They may judge a candidate who uses exclamation points as less serious. This study challenges that instinct directly. A single exclamation point signals engagement, not a lack of rigor. Treating it as a flaw may introduce bias without improving judgment.
| Situation | Exclamation Point Helpful? | Why |
|---|---|---|
| Welcome or thank-you email | Yes | Signals warmth and goodwill |
| Quick team check-in | Yes | Builds friendly rapport |
| Formal report or proposal | No | Analytical tone matters more |
| Disciplinary or legal notice | No | Neutral tone is safer |
| Job application follow-up | Use sparingly | One mark shows energy without excess |
Tips for Using Exclamation Points the Right Way
The study does not tell us to flood every message with marks. Context still matters. Here is a simple guide rooted in the research:
- Use one exclamation point in short, friendly messages. A “Thanks!” or “Great work!” goes a long way.
- Do not stack multiple marks. “Amazing!!!” feels forced and can hurt your credibility.
- 28 Look at how others around you write. Match their formality, not their exact phrasing. Mirroring tone shows awareness and empathy.
- Lead with substance. Clarity, facts, and deadlines should always come first. The exclamation point is a finishing touch, not a crutch.
- 10 It is important to be mindful of your emotions when crafting emails, as they can have a significant impact on your credibility. While it is great to show excitement, avoiding going overboard with exclamation points, smiley faces, and emojis is best.
“Don’t Overthink Your Use of Exclamation Points!” That is the actual title of the Harvard Business Review piece co-authored by the study’s lead researchers, Yidan Yin and Cheryl Wakslak.
There is also a generational angle worth noting. 3Gen Z participants aged 25 or less viewed the email senders who used exclamation marks as 22% more likable and about 16% warmer and more competent. If your team skews younger, a warm tone in emails could land even better.
As more of our work lives unfold inside inboxes and chat windows, the smallest choices carry surprising weight. This study reminds us that a single exclamation point is not a sign of weakness. It is a tool, and a powerful one when used wisely. For the women who have spent years second-guessing that choice before clicking send, the data is finally on your side. Your warmth is not your weakness. It never was. Drop your thoughts in the comments and let us know: do you think twice before adding an exclamation point to your emails
