Learn English – use “prompted with sth.”

Edit: as I reread your question, I see that I'm not really answering it. I am advising against using only for emphasis.

I taught foreign students, including students from Southern Asia, for 18 years.

While my case is different from yours, in that I had to communicate with people from multiple cultures, I think the following generalization holds: the reader or listener takes the culture of the writer or speaker into account.

Since you are not of the same culture, and you clearly do not understand all it's nuances (otherwise you wouldn't be asking the question), you should not try to use that dialect. It would be easy to accidentally convey unintended meaning, or even be seen to be condescending. As you mention, it is vital that you get the local office to review your writing. (This is a whole different area with potential for cross-cultural misunderstanding.)

All this suggests that you should just communicate in clear "international" English, using simple, unambiguous language. As you should with any audience.

As @Rupe said, it sounds like you have fixated on one meaning of the word corresponding. When in most cases today the word corresponds denotes a relationship between two things. See MW dictionary for the exact definition of how it's being used in your documentation:

2: directly related to something

In the US you rarely hear correspond used to denote a type of communication, and when I do hear it it's often by the news to talk about their "(foreign, technical, political) correspondent".

Appropriate, however tends to denote 'rightness' or 'correctness', see MW dictionary:

1: right or suited for some purpose or situation

So it can be used to denote a relationship, but in a broader sense then corresponding.
