得到 means you finally get something after making an effort. 收到 means someone sent you something and you got it.

其中一个区别是：“得到”有时候强调“经过努力之后最终获得”，例如，“经过几年的追求小伙子才得到她的心！”；“收到”在这个方面没有强调这个意思，例如，“周末，他收到她的来信”。所以说，“得到”常常强调人主动争取获得的积极态度，而“收到”往往没有这个意思。

得到 - you get something He got first prize in a competition. 他得到比賽第一名 收到 - someone give you something and you receive it I received a gift from him. 我收到他的禮物。

"de dao" means you achieve something (it can be an objective or some effort to get to a higher level) Ex: wo de dao gao cheng ji "shou dao" just simply means you get something concrete, such as when sb send you a gift you "shou dao" it Ex: wo shou dao ni de li wu

if you say 得到，it always means it's what you wanted. if you say 收到，it just means you receive sth. eg.我努力工作，终于得到了老板的赏识。 今天我收到了一张话费单。
