I have sent you an email to your hotmail account.  Can you let me know when you receive it.

 sana emaileri hotmail`inde gönderdim. onu aldin bana bilebilir misin

my try

 E-mail´i hotmail adresine gönderdim. (E-mail)´i aldığında bana bildirebilir misin ?( or bana haber verir misin ?)

isnt it "mail attım" better ?

 yes. Of course, real fans of TDK would insist on "ileti gönderdim" but everyone says "mail attım"

Sorry guys which translation is correct?  Thanks for all your help xx

 Go with Harpoon´s, either as it is, or with Reyhan´s suggested amendment

 Hi Elena, hope you don´t mind me explaining why the second sentence in particular needs changing:

It says. You got it can you know me.

Onu aldın= past tense = you got it.

If you want to say "when you get it" you need to say onu aldığında.

bilmek = to know

bilebilir misin = can you know.

You need to use bildirmek = to let me know, to tell me, to cause me to know.

bildirebilir misin

thank you very much

my best regards

sincerelly yours

elena
