Is it correct to write can you please send me?

The phrase "can you please send me?" is grammatically correct, but it's not a complete sentence. It's missing the object of the verb "send."

To make it a complete sentence, you need to add what you want to be sent. For example:

* Can you please send me the file?

* Can you please send me the link?

* Can you please send me an email?

You could also use it as part of a more polite request:

* Would you mind sending me the file, please?

* Could you please send me the link?

* I would appreciate it if you could send me an email.
