I don't get an email from this mac book since February of this year. What can I do?

Hi, byung256, see if you can use a web browser to login and send email ( “Web Mail” mode) if you can, then that means that your email is basically working… you might have to check on your isp’s ( internet service provider’s) web page to see what their settings for email are, you should also have your username and password( for email) handy… within the Apple mail application you can run “connection doctor”…. The default for Mac OS email is IMAP, and not POP/pop 3…. Sorry I can’t help you much more than this
