There is no one-size-fits-all answer to this question, as the decision of whether or not to italicize titles in newsletters depends on the individual’s preference and style. However, there are a few general guidelines that can help you decide if italicizing newsletter titles is appropriate in your work.
When creating a title for a journal article or newsletter, it is generally recommended that you use italics to denote different levels of emphasis. For example, a title that is written in all caps might be interpreted as an announcement or warning, while a title written in lowercase could be seen as more casual or conversational.
Similarly, italics can be used to denote specific words or phrases that are especially important or relevant to the article or newsletter topic.
Ultimately, it is up to the author of a piece to decide whether or not to italicize titles in their work. However, following these general guidelines may help you create titles that are easily understood and stylistically consistent.
