So I’m changing my old ihug e-mail address to gmail.... just deciding on what e-mail address to have as my current ihug one is too short apparently

I have an apple macbook pro and just using the default mail server that comes with it

My question is how do I add a new account so that I can send and receive e-mails from my gmail account?

I don't want to have to log in to gmail separately - I would like it to come through to the mail server on my macbook

any advice would be welcome thanks  :-)
