Facebook Announces a Unique Vision of Email

Facebook’s email vision didn’t last. The @facebook.com addresses launched with Facebook Messages in November 2010, and Facebook retired them in early March 2014, forwarding mail to each user’s primary address. The messaging side became Messenger, and email itself kept running on open standards. Since this post was written, Gmail, Yahoo and Microsoft have also started requiring SPF, DKIM, DMARC and, for Gmail and Yahoo, one-click unsubscribe from bulk senders, so authentication now matters more than any idea of social filtering.

The first reaction to Facebook’s announcement

The first verdict on Facebook’s new messaging system came down to one point. It looked very helpful for people who were on Facebook all day, and much less useful for the average, casual user.

It also looked a lot like Google Wave. In August 2010, a few months before Facebook’s event, Google said it would stop developing Wave as a stand-alone product after mainstream users found it confusing. You might have expected Facebook to learn from that. At the time, the only option was to wait and see. As it turned out, the email part of the vision went the same way.

What Facebook presented on November 15, 2010

Mark Zuckerberg and Andrew Bosworth showed the new system on Monday, November 15, 2010, at the St. Regis in San Francisco. Zuckerberg called it a “modern messaging system” built on three ideas: seamless messaging, conversation history and a social inbox. Here is what they announced, with notes on what happened later:

• Development: Bosworth said 15 engineers worked on the project for 15 months.
• Scale: Zuckerberg said about 350 million of Facebook’s roughly 500 million members used its messaging, sending more than 4 billion messages a day. That count covered private messages and chat.
• Format: The idea was to make messaging simpler, with shorter, quicker exchanges than “conventional” email. Subject lines, CC and BCC were dropped.
• Old email habits: Facebook argued that traditional email conventions were outdated. It also said whitelists weren’t a practical way for most people to filter mail, and used social connections to filter instead.
• One thread per person: Private messages, chat, SMS and email from the same person would all land in a single conversation history.
• A three-level inbox: The social inbox put messages from friends in the main inbox, sent messages from everyone else to an “Other” folder, and moved junk to its own folder. In October 2015 Facebook replaced the “Other” folder with Message Requests, which lets you accept or ignore a message from someone outside your network.
• Your username as your address: If your profile was facebook.com/yourname, your email address was [email protected]. Facebook retired these addresses in early March 2014.
• Integration: Facebook planned to support Jabber (XMPP), its own API and eventually IMAP. Once the @facebook.com addresses were gone, the IMAP plan no longer mattered.
• “Not an email killer”: Facebook said the system wasn’t meant to replace email. It was a simpler, more real-time way to communicate.
• Future plans: Facebook said it would connect with other email systems over time and add voice and video. Voice and video calls did arrive, but in Messenger rather than in email.

Facebook also said it would show ads in Messages. The rollout began by invitation. In February 2011, reports said the service would reach most of Facebook’s 500 million-plus users within two months.

That was the short version of the announcement.

I need an invite and get my hands dirty with this feature as soon as possible. Anyone out there care to send an invite my way?

Could Facebook Email take over conventional email

At launch, the big questions were whether Facebook Email would take over “conventional” email, flame out like Google Wave, or make no difference at all. Looking back, the answer is somewhere between the last two. The email address failed, and the messaging model succeeded once Facebook took email out of it.

In 2014, a Facebook spokesperson said most people hadn’t been using their Facebook email address, and that the company would focus on improving mobile messaging for everyone. The announcement came just days after Facebook agreed, on February 19, 2014, to buy WhatsApp for about $16 billion in cash and stock, plus $3 billion in restricted stock units. That deal showed where the company thought messaging was going: phones, chat and phone numbers, not inboxes.

What happened to Facebook Messages after 2010

Facebook’s messaging product changed shape several times after the launch. The email layer was gone by 2014, and the messaging layer kept moving between a standalone app and the main Facebook app.

As of November 2026, the Messenger mobile apps still work as usual. On desktop, messaging now happens inside Facebook itself. People who use Messenger without a Facebook account can only keep chatting in the mobile app.

What the experiment means for email marketers today

The lesson from Facebook Messages holds up well: email lasted because it runs on open standards that no single company controls. What has changed is that the big mailbox providers now enforce those standards much more strictly. They don’t decide what reaches the inbox by social connections. They look at authentication and how recipients react to your mail.

In February 2024, Gmail and Yahoo began enforcing bulk sender rules. Google applies them to senders who send more than 5,000 messages a day to Gmail addresses. Here is what bulk senders must do:

1. Authenticate with both SPF and DKIM.
2. Publish a DMARC record, with at least p=none, aligned with SPF or DKIM.
3. Support one-click unsubscribe in marketing messages and honor requests within two days.
4. Keep the spam rate reported in Google Postmaster Tools below 0.1%, and never let it reach 0.3% or higher.

On May 5, 2025, Microsoft began enforcing similar SPF, DKIM and DMARC requirements for senders who send more than 5,000 messages a day to Outlook.com, Hotmail.com and Live.com addresses.

A minimal DMARC record that meets the baseline looks like this:

_dmarc.example.com. IN TXT "v=DMARC1; p=none; rua=mailto:[email protected]"

Start with p=none and read the aggregate reports. Once every legitimate source of your mail passes, move to p=quarantine or p=reject. For practical purposes, this is how the “whitelist” problem Facebook complained about in 2010 got solved: through authentication, not friend lists.

FAQ

When did Facebook launch its email service?

Facebook announced Messages, which came with @facebook.com addresses, on November 15, 2010. It rolled out by invitation first. In February 2011, reports said it would reach most of Facebook’s users within the next two months.

Does an @facebook.com email address still work?

No. Facebook retired the addresses in early March 2014. At the time, it forwarded mail sent to an @facebook.com address to the user’s primary email, and users could turn that forwarding off. Don’t use these addresses for anything today.

Why did Facebook email fail?

Facebook said most people simply weren’t using their Facebook email address. People kept their regular email accounts for sign-ups, receipts and work. Meanwhile, Facebook’s own focus moved to mobile chat and its WhatsApp deal, worth about $16 billion in cash and stock plus $3 billion in restricted stock units.

Was Facebook Messages like Google Wave?

Both tried to merge email, chat and conversation history into one stream, and both were pitched as more modern than email. Google stopped developing Wave in August 2010 and shut it down on April 30, 2012. Facebook’s email layer ended in 2014, but the messaging product lived on as Messenger.

Can email marketers reach people through Facebook Messenger instead of email?

Messenger is a separate channel with its own rules set by Meta. It doesn’t replace an email list. Email still runs on open standards, and inbox placement depends on SPF, DKIM, DMARC, consent and low complaint rates. Under CAN-SPAM, commercial email also needs a clear way to opt out and a valid postal address.

What replaced the “Other” folder on Facebook?

In October 2015, Facebook replaced the “Other” folder with Message Requests. Messages from people outside your network now show up as requests that you can accept or ignore, and the sender doesn’t get a read receipt unless you accept.
