I sent invitation email for 2 friends, Well, after 1 hour first one told me thank you I received your email and I will be there. The second one told me, Hi lemme know when you send me an invitation.
I want to ask him, you didn't receive my email yet?
what's the most proper way to say?
Didn't you already receive my email yet?
Haven't you received my email yet?
1) Which one is correct?
2) There is another way to phrase it?
