I've already tried e-mailing the MEPs, it doesn't work. If you do get a response it goes in the lines of sorry mate, but you're wrong, here's why blah blah; our party consensus is that we're doing the right thing by voting for this controversial measure. Good luck with that.
That doesn't mean that contacting MEPs "doesn't work", you can't expect them to change their opinion immediately based on receiving one email from one of their constituents.
Use handwritten snail mail; generally the less effort a communication medium takes the less the politicians pay attention. Though with how many of them are on board you may want to start researching up on their opponents for the next election
