Expert writing Tips
Best practice
Place a comma before the phrase if it follows another imperative, such as 'Take care, and "please keep well".'
Common error
Avoid using "please keep well" when you actually mean to suggest performing an action skillfully; in those cases, you should specify the action, such as 'please keep the project running well'. Remember that 'well' in the target phrase refers to the person's state of being, not the quality of their performance.

Ludwig's WRAP-UP
In summary, "please keep well" is a highly effective and grammatically correct phrase for expressing concern for someone's health. While Ludwig AI notes that the specific three-word string is rare in its literal exact form, the underlying sentiment is a staple of polite English. It carries a dual meaning: most commonly as a warm wish for health (similar to "stay healthy"), and occasionally as a way to emphasize physical distance. Whether you are signing off a letter to a colleague or expressing care for a friend, it remains a versatile choice for modern writers.
