Hello,
I want to apply for European Voluntary Service programme and become a volunteer. To do so, I need to write a motivation letter. But I am hesitant about the style of letter. Should it be formal or not? What words it should begin with? I read somewhere that starting with words “Dear Sir/Madam” is not a good idea. So could you guys please help me? Every your advice on writing the motivation letter for this programme will be appreciated!!!
Thank you all in advance!
