这句话怎么翻译才比较是pure English？

Please write down the recipient's address and do not forget postcode.
或
Please write down the recipient's address and please add the zip code.

Please write down the address of recipients, and don't forget the postcode.
“and”就可以很好地连接两个部分，前后不是转折关系。而且，and是英语中比较常用的连接词，表示后面还有事情讲。这样表达，就比较native。

有个收件人地址的专有词：addressee，前面的句子就可以用Please write down the addressee, ...

Pls write down the recipients address and don't forget the post code.

呵呵

Please write the recipient's address, do not forget Zip
