Hey there,
I have done exactly this, but never got an answer to my email and for sure got another two scoops and two booklets.
As one of my main reasons for choosing JJ is your claim to be sustainable I start doubting how serious you are about that.
In another post about spillage it was argued by JJ that additional paper packaging of portions within the Plenny Shake package would be more unnecessary waste. Which by the way I would strongly agree with. But at the same time JJ is selling RTD Tetrapak packaged products with all the additional weight of water and - as far as I can tell - even worse packaging than the Plenny Shake packaging made from layered PE and PET. So how serious are you about sustainability?
But back to topic:
Should I write another email to not receive more unnecessary waste?
Maybe you want to add a box to your ordering form where one can put such additional infos? Or even a checkbox for scoop and booklet?
Please don’t make me search for another product as I am very happy so far with Plenny Shake! 
thanks for caring
reini
