Geo Mail (it is a mobile link - iPhone, Android, Samsung) provides an email form where you type your message title and body and choose whether you want to include a link to either a scrollable or static Google map or just your latitude and longitude. When you hit the "Send" button GeoMail opens your device's default Email app with the message and location information pre-populated, all you have to do is specify the recipient and send the email.
