Hello everyone!

Tree questions, actually:

1) If someone had asked you with a letter to provide some information, you had done it and recieved a letter with thanks, would you reply? (If the person you communicate with is a stranger to you)

2) I know several ways of informal reply to a 'thank you': 'no problem', 'don't mention it'... Could anyone suggest other words (just in order to make the language brighter)?

3) And, of course, more formal replies: 'It was my pleasure', 'Glad to help', etc. What else can we say?

"You are Welcome, 'person's name'."
Kind regards,
your name
I have found this to work very well especially with coworkers.
I think something like... "You're welcome... please let me know if there's anything else I can help with"...
