From now on, emails sent to an "@facebook.com" address will be forwarded to the personal email address from which the member signed up for the site.
"We're making this change because most people haven't been using their Facebook email address," said a Facebook spokesperson.
The change will happen in early March.
The service was launched in November 2010 and billed as a way to streamline users' communication by providing a single inbox that could receive Facebook messages, SMS texts, and conventional emails.
It came under fire
in 2012 when Facebook replaced users' published email addresses with their "@facebook.com" email on their profile.
The company later reversed course.
