How do I send an email to someone on ps
If by "e-mail" you mean a private message:
Go to "Friends" in your XMB > Message Box > Send New Message
Put in the person's PSN ID you are writing, type your message, and send.
If they are already on your Friends List, just highlight their name, push triangle, and select the option to send them a message.
If you're referring to an actual email as opposed to a message from the XMB. You can not, unless you know the persons actual email.. Or I may just be over thinking the question..
Get your Portable ID!
