How to send email from my Iphone to my lop top?

Why my email go different areas (IPHONE & LAP TOP)?

Sure you can, open up the mail app on your phone if you have it set up with your email account and type the email address and email that you have set up on your laptop press send and it will go.

If you don't have it set up then just choose add account and add your email account.

As long as you have an email Account set up you can even send to yourself. If you send to the same email account it will be received on both your phone email account and your laptop.

I have all my email accounts set up on my phone, my iPad and my computer and when I receive an email it comes into all three.
