I am not expert by any means but I think your 2nd response is better only because you seem like the stronger person, you are not coming across as angry as well you are not letting him walk all over you. The only thing I would change is maybe the gift idea, are you comfortable buying a gift with him? If so then keep this email the same, if not you can still word that nicely as well.
It is funny how the WH still contact us to plan their lives, my WH does it all the time with the kids and I cannot figure out why he does not just do it on his own. However it may just be that your WH and mine just want some form of contact and they are also checking to see how you will react.
So stay strong, positive and pretend like nothing is wrong.
