1. Use either "Please" or "Kindly" but not both. If you use both, one is redundant because in this context they mean the same thing.
2. Who is writing the sentence?
3. Who are they writing to?
Note my corrections above. "Crystal clear" is the adjective you're looking for. We don't use "crystal clearly" and if we did, it would an adverb.
I have changed your thread title so that it is relevant to this thread. Titles should include some or all of the words you are querying.
