Adjust “Review” button in e-mail

Hi,
I’ve set the plug-in to Dutch, and everything works perfectly, except for one thing:
In the email that is sent to the customer, asking for a review, there is a button at the bottom (in dutch labeled “Beoordeling”). Probably because this word is longer than the English equivalent, it comes out wrong though. It says “Beoordelin”. The last letter, the ‘g’, drops below on the second line, but since the button is not that high, it is unreadable. This looks very unprofessional.
Can you adjust the button size so it will hold longer text than ‘Review’?
Regards,
