Hi,

By this time, the email should have arrived.
By this time, you should have received an email.

Are they okay/correct?

They're OK but unless you are talking about a specific time (ie 4pm), I would say "The email should have arrived by now" or "You should have received an email by now".

Great! Your sentences are better than mine and I will follow those. Well, can you please give me just an example with time if it is different when it comes to time?

Please check your inbox tomorrow afternoon at 4pm. By that time, you should have received my email.

Note that although correct, it's an unlikely construction and we are more likely to say "Please check your inbox tomorrow afternoon at 4pm. By then, you should have received my email".
