I would like to use this phrase in my formal correspondence. Translation with dictionary does not help, it results with something like "M'яке нагадування", which doesn't seem plausible.
Do you have any suggestions or correction or maybe know alternative phrases?
Formal correspondence in Ukrainian is generally a bit more strict than in English. If it is necessary to send a reminder, it is sufficient to say
Нагадуємо вам, що...
Хочемо нагадати про...
and add "Дуже дякуємо" or similar at the end.
"М'яко нагадуємо" is acceptable and is becoming more common due to globalization, but still has a distinct feeling of using an English phrase in Ukrainian.
You should use the 'делікатне нагадування'.
This article at DiloMova provides with several different ways to translate "gentle reminder", depending on your attitude to the nature of the matter being reminded of.
The word "gentle" can be translated in a number of ways into Ukrainian, there is no Ukrainian word that corresponds to "gentle" one-to-one. "M’яке нагадування" sounds pretty well ("soft reminder"), but if you do not like it, maybe "лагідне нагадування" will suit you better. "Лагідний" is much close to "gentle" in its meaning than "м’який".
