Learn English – How to translate “mention bien” and “mention très bien” in English

There are myriad ways to express a sentiment similar to the one you describe. Here are a few examples:

The above is purely for your information.

This is solely by way of information.

I write this simply to keep you informed of the situation.

. . . keep you apprised . . .

. . . keep you in the loop.

In my experience (mainly in the world of business), including this sort of phrase in a letter serves to clarify that the recipient is not expected to take specific action at this time. If you want a more general phrase to accompany an informative letter, you might also try:

I hope you find this useful.

By way of agreement with commenter jmoreno, I will add that the most similar practice I have observed in AmE (especially in the business world) is to introduce information that is included purely for information's sake. Often this will occur as early as the subject line of an email, which could begin with “FYI:” without appearing too informal.

Company names tend to not be translated.

But as discussed here, sometimes a translation is required.

(Taken from link above)

Depending on the situation, it might be appropriate to add a translation, in italics, between square brackets, immediately following the company name. Especially if the company or agency name is an acronym.

Example: when translating from Italian to English, it might be really useful for the reader to know that "FFSS" means [Ferrovie dello Stato - Italian State Railways].

But in general, translating company names might lead to strange outcomes: FIAT (Fabbrica Italiana Automobili Torino) would translate as "Italian Automobile Factory, Turin - IAFT"

You need to make your own judgment as to whether a translation of the company name would be expected or would help to clarify the translation as a whole.
