Is there a better way to say 'feel free to get back to me later'? [closed]

I'm writing an email to ask my friend some questions, it's on the weekend so I just want to be polite and let him know it's okay to get back to me later. Is there a way I can express this meaning while not being so formal? Thanks!!


Good question actually, since this is quite a common requirement when talking to friends, I have found.

  • No need to write back straight away!
  • No rush to respond!
  • Take your time, no need to respond straight away!
  • You don't need to get back to me straight away!

And so on.
