What about the ms or mr on inside address could it be open punctuation?

You're right, it's a common question! The use of "Ms." or "Mr." within an inside address can be open punctuation. Here's a breakdown:

Open Punctuation:

* No punctuation after "Ms." or "Mr." This is a more modern style and is increasingly preferred in business writing. It emphasizes clarity and readability.

* Example:

* Ms. Jane Doe

* Mr. John Smith

Closed Punctuation:

* Period after "Ms." or "Mr." This is the traditional style, but it's becoming less common.

* Example:

* Ms. Jane Doe.

* Mr. John Smith.

The Key Takeaway:

Ultimately, the choice between open and closed punctuation depends on the preferred style guide of your organization or the specific recipient.

Additional Points:

* Consistency is crucial: Within a single document, stick to one style consistently.

* Professional Judgment: In some cases, it might be wise to err on the side of closed punctuation for more formal situations or older recipients who may be accustomed to it.
