According to one study, maybe not. From the Trust Advisor:
In fact, when texts or other computer-mediated communication (CMC) messages are followed by a period, the sender is perceived as insincere, according to a study by researchers at Binghamton University’s Celia Klin recently published in the scientific journal Computers in Human Behavior.
This is not the case when the period is used in hand-written notes, however, which leads Klin and her colleagues to conclude that the period text messages has taken on new meaning and is no longer the right way to finish your sentences when using CMC, according to the [Washington] Post.
Furthermore, and perhaps to the dismay of polite society everywhere, follow-up research not yet published is expected to show that exclamation points, rather than no punctuation, is what you should use to seem more sincere, the Post writes.
You can read more here. The study’s subjects were college students. I would wait for more studies.
