A quiet but significant change has rolled out to millions of Gmail users. Since 2026, Google has removed two features that many considered essential to the service’s convenience. Those managing multiple mailboxes through a central Gmail account will face noticeable limitations.
Since the beginning of the year, Gmail has disabled two key features: integration via Gmailify and access through the POP3 protocol. This notice is visible, among other places, when logging into a personal email inbox. Users of third-party accounts will need to adapt to continue retrieving emails.
Overview
Google Discontinues Gmailify and POP3 in Gmail
Gmailify allowed third-party mail accounts like Yahoo or Outlook to connect with Gmail, offering enhanced features such as spam filters, inbox categories, and improved search options. Push notifications were also among the benefits. These capabilities are now completely eliminated.
Regarding the POP3 protocol, Google slightly delayed the shutdown schedule, giving users more time than initially expected. The original deadline was set for the end of January. Google then changed its stance, announcing that support for new users would end in the first quarter of 2026–affecting those who hadn’t used POP3 by then.
Those already actively using the protocol can continue to do so for now. However, its end is foreseeable: POP3 will be completely shut down for existing users sometime in 2026. Google has not yet provided an exact date.
It’s clear: POP3 is definitely on its way out at Gmail–albeit with an extended timeline. Those who have relied on integrating external accounts through this older protocol should start looking for alternatives early.
IMAP Becomes the New Mandatory Solution
To continue accessing third-party accounts, Google recommends switching to the modern Internet Message Access Protocol (IMAP). Unlike POP3, IMAP is still supported and allows email synchronization directly on mobile devices like Android smartphones or iPhones via the Gmail app. This usage occurs without the usual Gmail extras such as spam protection or categorization.
Google explicitly advised users to check their mail settings and make the switch early. As an alternative to the previous POP3 retrieval, automatic forwarding can be set up with the external email provider to have new messages appear in the Gmail inbox.
For users of external, local mail clients, it remains possible to locally secure emails independently of Gmail–for example, by moving or copying messages from an IMAP-linked mailbox to local folders.

How to Identify How an External Mail Account is Linked
To check which external mailboxes are integrated into Gmail via POP3, follow these steps:
- Open Gmail in the browser.
- Click the gear icon in the top right → See all settings.
- Go to the Accounts and Import tab.
- Under Check mail from other accounts, all accounts integrated with Gmail are listed.
If entries are still found here, such as with POP3 integration, you need to take action and switch to IMAP. Ensure that IMAP is enabled on both email clients. At Gmail, this has been the default since January 2025.

Users Face Challenges
Gmail generally supports retrieval for external mailboxes like GMX only through the older POP3 protocol. A full IMAP integration, where folders, structures, and changes remain synchronized between both mailboxes, is not provided by Google. Therefore, external accounts cannot be directly integrated into Gmail via IMAP, and importing the complete folder structure is technically excluded.
To reliably receive all new messages in Gmail even after the shutdown of POP3 and Gmailify, users must set up automatic forwarding. This ensures incoming emails are immediately delivered to the Gmail account–without the limitations that come with the lack of IMAP support.
Previously imported emails will remain in the Gmail account even after the mentioned functions are discontinued. It is also still possible to perform one-time imports of messages and contacts from third-party accounts. However, ongoing synchronization as before will no longer be possible.
