Gmail’s 2027 Shutdown of External POP Fetching and Send As
You read and answer your business address’s mail from inside Gmail. When that stops in January 2027, how will clients’ messages reach you, and where will your replies come from?
- In January 2027, Gmail stops fetching external mail through POP or Gmailify and sending as a non-Google address. If you use Gmail for a separately hosted business mailbox, you need a replacement for replying as well as receiving.
- Forwarding can preserve incoming mail in your Gmail inbox. Sending from the external address needs a separate route, such as its provider’s webmail or a directly connected account in a mail app.
- Before removing the old setup, have a test recipient reply to your new outgoing message. Confirm that their answer returns to the business mailbox, and locate your outgoing copy in the intended account’s Sent folder.
If Gmail has been your front end for a separately hosted business mailbox, replacing POP fetching with forwarding solves only the incoming half of that arrangement. You also need somewhere to send replies using the business address. Google’s third-party account announcement includes the removal of external Send As in January 2027. A message can still arrive in Gmail through forwarding after that change without giving you a way to reply from the address your customer wrote to.
A user seeking an alternative describes the practical constraint: other family members share the domain, so moving its mail hosting is not a simple personal decision. Adding both accounts to the phone also leaves the desktop web workflow unresolved. You can keep both addresses without necessarily moving the whole domain; the work is deciding how incoming messages and outgoing replies will travel.
What ends in January 2027—and what stays
Gmail’s “Check mail from other accounts” fetches messages from an external mailbox using POP. Gmailify applies certain Gmail features to a linked external account. The Gmailify and POP FAQ separates new and existing users: new users stopped being supported after the first quarter of 2026, while existing users can continue until January 2027. A connection still working today is not evidence that it is exempt.
External Send As is also ending. This is the arrangement in which your primary Gmail account sends using a separately hosted address. Google-hosted identities, including other Gmail addresses and Google Workspace aliases, are excluded from that change. A business domain does not by itself identify the hosting provider: a company address hosted by Workspace is different from one hosted elsewhere.
Direct access to an external account through the Gmail mobile app remains supported. So does accessing Gmail itself from Outlook, Thunderbird, or another client using IMAP or POP. “Gmail is ending POP” is therefore too broad a description. The affected workflow is Gmail fetching external mail, alongside its external-address sending feature.
Choose where you will read and send
Consider an illustrative order address, [email protected], hosted outside Google. You currently read its incoming orders in Gmail and choose that address when replying. The following replacements preserve different parts of that experience.
| What you want to retain | Replacement arrangement | What changes |
|---|---|---|
| Incoming mail in Gmail on the web | Provider-side forwarding, with replies sent through the provider’s webmail | Reading and replying use separate interfaces. |
| Both accounts on your phone | Add the external account directly to the Gmail app | The mobile combined view does not recreate the desktop web inbox. |
| Several accounts in a desktop application | Connect Gmail and the external account separately to a mail client | You install and configure an app, then select the sending account. |
The first option suits someone who needs browser access and can tolerate opening another mailbox to reply. The second works well when most correspondence happens on a phone. The third provides a desktop place to work with both accounts without asking Gmail’s web service to fetch the external one.
Before changing anything, inventory the existing setup under Gmail Settings → See all settings → Accounts and Import. Record both the external fetching entry and the sending address, including the default sender and reply-to configuration. Google’s Send As instructions now carry the retirement notice. Recreating an external Send As entry is not a durable migration plan.
Forward mail from the provider that receives it
Set forwarding at the external mailbox’s provider, with your Gmail address as the destination. Setting Gmail to forward outward would send mail in the opposite direction. Ask the provider whether automatic forwarding is available for your account and whether an administrator must allow it.
For a personal Outlook.com account, Microsoft’s current forwarding guide gives this route: open Settings → Mail → Forwarding and IMAP, select Enable forwarding, enter the destination address, and save. Complete any additional sign-in prompt. These are Outlook.com instructions; classic Outlook rules and organizational Outlook settings have their own paths.
If you use an inbox rule, distinguish Forward to from Redirect to. Microsoft’s rule documentation explains that a reply to a forwarded message goes to the forwarding account, while a reply to a redirected message goes to the original sender. In Outlook.com, these actions are available through Settings → Mail → Rules.
That distinction determines the recipient of your reply. It does not grant Gmail permission to send as your business address. Check both To and From: replying to your own forwarding mailbox and replying from your personal Gmail address are two different errors.
You do not need to begin by changing the domain’s mail-server records. A mailbox-level forwarding arrangement or direct app connection may be sufficient. This is especially useful when colleagues or family members use other addresses on the same domain and are not moving their mail.
Connect the external account directly on mobile or desktop
In the Gmail mobile app, add the external account itself rather than relying on an alias attached to your primary Gmail account. Google’s iPhone and iPad instructions start with the profile picture, then Add another account, the provider’s name, and its sign-in process. For an unlisted provider, use Other (IMAP) with the settings supplied by that provider.
The app’s Menu → All inboxes view can display multiple accounts together. It does not merge their stored messages into your Gmail account on the web. Switch to the external account and send a test message from it so you know which address the recipient will see.
On a PC, a client such as Thunderbird can connect to both mailboxes. Its official account setup guide describes entering an existing account, checking the automatically discovered configuration, and completing the provider’s authentication. IMAP is normally the preferred option. If discovery fails, obtain the provider’s manual configuration rather than copying another service’s server names.
Ask for incoming IMAP and outgoing SMTP settings, ports, encryption, and the required sign-in method. SMTP is the sending connection. Seeing an inbox populate does not prove that outgoing mail works. Add the Gmail account separately if you also want to reach correspondence already stored there; connecting only the external account will not bring Gmail-only archives into it.
Test a complete conversation before switching over
Use a separate address you control and a recognizable subject. Send the reply through provider webmail or the directly connected external account. A successful reply through the retiring Gmail Send As entry would only test your old setup.
- Send a fresh message to the external business address. Verify that it arrives in the provider’s own mailbox.
- Confirm it reaches Gmail through forwarding, or appears in the directly connected external account if that is your chosen arrangement.
- Reply through the interface you plan to use. Check that To identifies the test sender and From identifies your business address.
- Open the reply at the test address. Inspect its actual sender and reply destination, then locate the outgoing copy in the sending account’s Sent folder.
- Reply again from the test address. Check that the recipient is the business address before sending, then confirm arrival in the provider’s original mailbox. If forwarding is part of the arrangement, check the Gmail copy as well.
A business address in the received message’s From field does not by itself show where the recipient’s next reply will go. If that reply targets your personal Gmail or a forwarding address, compare the new sending account’s Reply-to setting with the intended destination. A different problem occurs when you reply to an incoming forwarded copy and To points back to your own external mailbox: check the Forward versus Redirect behavior described above. Successful incoming forwarding does not establish either reply path.
If the original mailbox receives the message but Gmail does not, compare the provider’s mailbox with Gmail’s Spam folder. Google’s forwarding recommendations explain that forwarding can affect authentication. SPF may fail along the changed delivery path, and changes to signed headers or message content can break DKIM validation. Give the provider specific missing-message examples, times, and errors instead of assuming all forwarding is broken.
Also watch the overlap period when old POP fetching and new forwarding are both enabled. A message may reach Gmail through two routes; do not mass-delete apparent duplicates before comparing their contents and confirming the new route. If you retain messages at the original provider, monitor that mailbox’s capacity. Microsoft notes that its forwarding and redirect rules retain copies and that a full mailbox can prevent delivery and forwarding.
Keep old correspondence available during the transition
Previously imported messages remain in Gmail. You can continue searching that archive while sending new replies through the external account. You do not have to move every historical message before the new workflow becomes usable.
For active conversations, locate the latest reply and attachments before changing your daily interface. Some older messages may exist only in Gmail, depending on how you previously handled the external mailbox. Adding that external account to a new app does not restore those Gmail-only copies to its server.
Google’s import FAQ also distinguishes one-time mail and contact imports from continuous synchronization. Importing history today does not establish a route for tomorrow’s orders. Once you can receive a fresh order, reply from the intended address, and find the sent copy, retire the old fetching and external Send As configuration in line with your chosen workflow.
