Facebook did open its messaging system to ordinary email. In November 2010 it gave users an @facebook.com address, then retired the service in February 2014 because, in a spokesperson’s words, “most people have not been using their @facebook.com email address.” As of November 2026 Facebook has no email service. Messenger is a chat app on phones and at facebook.com/messages, after Meta shut its Windows and Mac desktop apps on December 15, 2025 and closed messenger.com in April 2026. Email never got turned “on its head.” The bigger change came from Gmail, Yahoo and Microsoft, which since 2024 and 2025 have required bulk senders to authenticate with SPF, DKIM and DMARC, offer one-click unsubscribe and keep spam complaints low.
The original post
If you use Facebook, the social networking site of the moment, you may notice that its email options have widened considerably. Until recently, Facebook messages stayed inside the site and could only go to other Facebook users. Now Facebook lets you send messages to regular email addresses through its system.
Historical note: this widening became official on November 15, 2010, when Facebook announced the messaging system it had built internally as “Project Titan.” It combined Facebook messages, chat, SMS and email in one inbox, and any user who wanted one could get an @facebook.com address. Mark Zuckerberg told the press, “This is not an email killer,” and called it a messaging system that included email as one part. At the time, he said more than 350 million of Facebook’s half-billion users were actively sending and receiving messages on the site.
The problem with Facebook’s email service is that, as things stand, almost nobody uses Facebook as their only way to send email. Most people check their main email account to see whether a notification has arrived from the social networking site. Then they log in to the site to actually read the message. That seems a little convoluted, for now. If Facebook adds a few key features, such as POP access and forwarding, it could turn the email marketing world on its head.

What happened next
The convoluted workflow described above turned out to be the whole story. Facebook never became anyone’s main inbox, and it closed the email side of the service within about three and a half years.
| Date | Event |
|---|---|
| November 15, 2010 | Facebook announces Messages with optional @facebook.com email addresses |
| June 2012 | Facebook replaces the email addresses shown on users’ profiles with their @facebook.com address, which causes a backlash |
| February 24, 2014 | Facebook retires @facebook.com addresses and forwards incoming mail to each user’s primary email on file |
| 2014 | Messaging moves into the separate Messenger mobile app |
| December 15, 2025 | Meta shuts the Messenger desktop apps for Windows and macOS |
| April 2026 | Messenger.com closes and redirects to facebook.com/messages |
The 2014 shutdown also exposed a privacy weakness. Each address was built from the user’s profile name, so anyone could work out an address from a profile URL. When forwarding was switched on, mail sent there landed in the person’s real inbox. Users who had never added a primary email address simply stopped receiving anything sent to the old address.
What this means for email marketers today
POP access and forwarding were never what mattered. Owning the inbox mattered, and the inbox stayed with Gmail, Yahoo, Outlook.com and Apple Mail. If you send marketing email in 2026, those providers’ rules are the ones that count:
- Gmail and Yahoo (from February 2024): if you send roughly 5,000 or more messages a day to their users, you need SPF, DKIM and a DMARC record. You also need one-click unsubscribe, unsubscribes honored within two days, and a spam complaint rate kept below 0.3%. Google advises staying under 0.1%.
- Microsoft Outlook.com (from May 5, 2025): domains sending more than 5,000 emails a day to Outlook.com, Hotmail.com and Live.com addresses must pass SPF and DKIM and publish DMARC with at least
p=none. Mail that fails can be rejected with error550 5.7.515. - CAN-SPAM in the US: every commercial email needs accurate header information, a non-deceptive subject line, your valid physical postal address and a working opt-out that you honor within 10 business days.
A minimal DMARC record that meets the starting requirement looks like this:
_dmarc.example.com. TXT "v=DMARC1; p=none; rua=mailto:[email protected]"
Start with p=none so you can read the reports. Once all your legitimate sending sources pass, move to p=quarantine or p=reject.
Your open rates have also changed since this post was first published. Apple Mail Privacy Protection preloads images, which inflates opens, and Gmail serves images through its own proxy. Clicks, conversions and complaint rates tell you more than opens do. Most email is now read on phones, often in dark mode, so design for a narrow screen and test your logos and colors on dark backgrounds.
FAQ
Does Facebook still offer an @facebook.com email address?
No. Facebook retired @facebook.com addresses in February 2014. Mail sent to an old address was forwarded to the user’s primary email on file, provided they had added one. Facebook has not offered an email service since.
Can you email Facebook users through Messenger?
No. Messenger is a chat service, not an email system, and it does not accept mail sent to an email address. You can only reach people there through Messenger itself, on Meta’s own terms, which is one reason marketers keep building lists they own.
Where can you use Messenger on a computer in 2026?
Use facebook.com/messages in a web browser. Meta shut the Windows and Mac desktop apps on December 15, 2025, and messenger.com started redirecting to Facebook in April 2026. The iOS and Android apps were not affected.
Did Facebook’s email service ever affect email marketing?
Not much. Few people used their @facebook.com address, so it never took a real share of the inbox from Gmail, Yahoo or Hotmail. The changes that did reshape email marketing came later: Gmail’s inbox tabs, Apple Mail Privacy Protection, and the 2024 and 2025 bulk sender rules.
Should you collect email addresses from Facebook to build your list?
Only with clear consent. Getting people to opt in through a sign-up form you promote on Facebook is fine. Scraping addresses from profiles or buying lists breaks platform rules and spam laws, and it pushes your complaint rate past what Gmail and Yahoo allow.
What do you need to send bulk email to Gmail, Yahoo and Outlook today?
You need SPF, DKIM and DMARC on your sending domain, a one-click unsubscribe header, and a spam complaint rate below 0.3% (Google suggests under 0.1%). Microsoft enforces similar rules for anyone sending more than 5,000 messages a day. US senders also have to follow CAN-SPAM: a valid postal address and opt-outs honored within 10 business days.
