According to Daniel Post Senning, co-author of "Emily Post's Etiquette: The Centennial Edition," certain sensitive topics should not be communicated through text messages. One of the most commonly cited examples is break-ups. However, the range of topics that need to be handled delicately extends beyond this. Senning suggests that sharing news of someone's passing or conveying bad health information, such as a negative diagnosis, should also not be done over text. Additionally, he implies that even good news, such as a marriage proposal or finally moving to your dream city, might be better communicated over the phone or in person.
In essence, any conversation that is likely to be emotionally charged should be conducted through a medium that allows for the expression and reception of tone, volume, and body language, elements that are lacking in text communication. These elements can significantly alter how a message is understood and responded to. Therefore, sensitive topics, which usually evoke strong emotional responses, are better discussed in person or over a call, rather than through text messages.

The main guideline Daniel Post Senning suggests regarding the type of conversations that should not be conducted over text messages is to avoid any conversation that is likely to be emotionally charged. According to Senning, it is important to give yourself the best chance possible to bring all your emotional tools to such conversations, which can be better achieved through tone, volume, and body language that can't be conveyed over text.

According to the article, both good and bad news are better communicated via phone call or in person because these types of conversations are often emotionally charged, and it's important to bring all of one's emotional tools to the conversation. Tone, volume, and body language can all help alter how a message is received, and these elements cannot be conveyed effectively through text messages. By having these conversations over the phone or in person, individuals can better express and understand the emotions involved, leading to more effective communication and a better understanding of the news being shared.
