How to Set Up Gmailify and Prepare for the 2026 Shutdown
How to Set Up Gmailify and Prepare for the 2026 Shutdown

This Gmailify setup guide covers three things: how to use Gmailify (if the option still appears in your Gmail app), what changes to expect during the Gmailify sunset in 2026, and a practical replacement workflow so you’re not stuck when syncing stops. [1][2] If you’re planning ahead, explore Gmail alternatives that don’t depend on Gmailify.

The replacement is straightforward: connect each mailbox directly using IMAP (and use “Sign in with Google”/OAuth for Gmail when offered), then manage everything in a Gmail desktop client with a unified inbox. In Mailbird, you can keep multiple Gmail accounts and other providers together on one screen without relying on Gmailify as the middle layer. [3][4][5]

If you don’t see “Try Gmailify” or “Link account” anymore, treat that as normal during the phase-out and move straight to the IMAP workflow. [1]

What’s new Gmailify + POP changes in 2026

Google is phasing out both Gmailify and Gmail’s POP-based “Check mail from other accounts” in 2026. The official timeline says new users will lose the ability to set these up by the end of Q1 2026, and existing users can keep using the features until they’re turned down later in 2026. [1] If you’re evaluating your next setup, review Gmail alternatives that don’t rely on Gmailify or POP fetching.

Key takeaways

  • Gmailify is Gmail’s “link account” feature for certain non-Gmail providers (for example, Yahoo, AOL, Outlook/Hotmail, and select other accounts). [2]
  • Google is phasing out Gmailify and Gmail’s POP-based “Check mail from other accounts” in 2026; new setups end by the end of Q1 2026. [1]
  • If Gmailify setup options no longer appear, treat that as expected during the phase-out and move to an IMAP-based setup. [1]
  • You can recreate “everything in one place” by connecting each mailbox directly (IMAP/OAuth) and using a unified inbox view on desktop. [4][5]
  • For Gmail accounts, prefer “Sign in with Google” (OAuth) when available instead of typing your Gmail password into apps. [3]
  • After you test your new setup, unlink Gmailify and decide whether to keep already-synced copies in Gmail. [2]
  • If you see duplicates after switching, pick one delivery path (for example, avoid forwarding + IMAP at the same time). [2]

Quick plan (the long-term fix)

  1. Add accounts directly to Mailbird. Use “Sign in with Google” for Gmail when available; use IMAP for other providers.[3][5]
  2. Enable Unified Inbox. Read across accounts from one view, while still sending from the right address.[4]
  3. After testing, unlink Gmailify. This helps you avoid duplicates and makes direct IMAP your main delivery path.[2]

Before you start

  • Prerequisites: Working sign-in for every mailbox you want to keep (and your 2-step verification device, if enabled).
  • Tools: A computer, Mailbird installed, and (for custom domains) your IMAP/SMTP server details from your email provider.
  • Time: One focused session for setup; allow extra time if you’re syncing years of email for the first time.
  • Cost: $0 if you use Mailbird Free; paid plans are optional.[6]
  • Safety notes: For Gmail accounts, prefer “Sign in with Google” (OAuth) instead of typing your Gmail password into apps when possible.[3]

Gmailify setup: what it is and how to use Gmailify (temporarily)

Gmailify is Gmail’s “link account” feature for certain non-Gmail providers (for example, Yahoo, AOL, Outlook/Hotmail, and select other accounts). When it’s linked, mail from that address shows up in Gmail and you get a more “Gmail-like” experience (such as spam protection and Gmail-style organization/search).[2]

  1. Add the non-Gmail account to the Gmail app (if you haven’t already).
  2. Look for the Gmailify prompt:
    • On iPhone/iPad, you may see a Try Gmailify option after adding the account.
    • On Android, you may see Link account inside the account’s settings.
  3. Follow the on-screen steps to confirm the link.[2]

After linking, your messages can appear in Gmail on mobile and on the web, and Gmail can organize them similarly to a Gmail inbox.[2]

  1. In the Gmail app, open Settings.
  2. Find the Gmailify/linked account area, then tap Unlink.
  3. When prompted, choose whether to keep copies of the already-synced messages in Gmail.[2]

Once you unlink, Gmail stops showing new messages from that other account. If you keep copies in Gmail, changes you make to those copies (like moving or deleting) won’t necessarily affect the original mailbox at the other provider.[2]

Gmailify changes in 2026: the Gmailify sunset (what to expect)

Google is phasing out both Gmailify and Gmail’s POP-based “Check mail from other accounts” in 2026. The official timeline says new users will lose the ability to set these up by the end of Q1 2026, and existing users can keep using the features until they’re turned down later in 2026.[1]

When (per Google) What you can expect
By the end of Q1 2026 New Gmailify links and new POP-based “Check mail from other accounts” setups are no longer available.[1]
Later in 2026 Existing Gmailify and POP-based fetching connections are turned down.[1]
When (per Google)
By the end of Q1 2026
What you can expect
New Gmailify links and new POP-based “Check mail from other accounts” setups are no longer available.[1]
When (per Google)
Later in 2026
What you can expect
Existing Gmailify and POP-based fetching connections are turned down.[1]

What typically changes first

  • You may no longer see “Try Gmailify” / “Link account” for new setups.[1]
  • Your existing linked account may stop syncing into Gmail during the turn-down window.[1]

What you lose when Gmailify is gone

  • Gmailify-specific benefits applied to the third-party account (for example, Gmail-style spam protection/organization and other Gmail features for that account).[1][2]
  • Continuous POP-based pulling of messages into Gmail on desktop via “Check mail from other accounts.”[1]

What stays true

  • Messages that were already synced into Gmail can remain in Gmail.[1]
  • You can still use third-party email accounts in the Gmail mobile app via standard IMAP (with fewer Gmailify-specific perks).[1]
  • You can still connect Gmail itself to other email apps using POP or IMAP (this change is about Gmail acting as the “collector” for other providers).[1]

What can change

Google’s exact shutdown timing can shift, and the rollout may look different by account/provider. If your workflow depends on Gmailify, assume it can stop working at any point during 2026 and keep your replacement workflow ready.[1]

The replacement workflow: IMAP + a Gmail desktop client + Unified Inbox

Gmailify’s big value was “one place to manage everything.” You can keep that convenience by connecting to each mailbox directly (IMAP/OAuth) and using a unified inbox view on desktop. In Mailbird, you add each mailbox once, then use Unified Inbox to read across accounts from a single screen while still replying from the correct address. If you want to compare that workflow with staying inside Gmail, see Mailbird vs Gmail.[4][5]

For Gmail accounts, aim for an OAuth flow (“Sign in with Google”) when possible—Google describes this as a safer way to sync Gmail to other apps.[3] This approach also keeps a consistent Gmail workflow for people juggling multiple Gmail accounts (personal, work, side projects) without constant account switching.[4]

Step-by-step: Gmailify migration to Mailbird (IMAP + Unified Inbox)

Step-by-step: Gmailify migration to Mailbird (IMAP + Unified Inbox)

  1. Make a simple account list.

    Write each email address you need (including multiple Gmail accounts), what you use it for, and whether you must be able to send from it.

  2. Confirm whether Gmailify is currently linked.

    On your phone, open the Gmail app and look for a Gmailify/linked account section for the non-Gmail address. If it’s linked, take a screenshot so you remember what’s connected before you change anything.[2]

  3. Sign in to each original mailbox in a browser.

    Confirm you can open the inbox and send a test email (to another address you own). Fix password/recovery issues now—before you set up IMAP.

  4. Enable IMAP at your non-Gmail provider (and create an app password if required).

    In the provider’s web settings, find “IMAP,” “Mail apps,” or “App passwords.” Turn on IMAP. If the provider requires an app password for desktop clients, generate one and save it in a password manager.

  5. Open Mailbird and go to the Accounts screen.

    In Mailbird, open the menu → Settings → Accounts, then click Add to connect a new email account.[5]

  6. Add your first Gmail account using “Sign in with Google” (OAuth).

    Add the Gmail address, then follow the Google sign-in window. If you need the manual path, use this Gmail IMAP setup guide. If you’re prompted to choose an authentication method, use OAuth 2.0 rather than username/password.[3][7]

  7. Add your other Gmail accounts (repeat the same process).

    This is a clean way to keep multiple Gmail accounts in one place without browser profiles or constant account switching.

  8. Add your non-Gmail account(s) in Mailbird using IMAP.

    Click Add again, enter the address and password/app password, and choose IMAP when asked. Wait until you see messages begin to populate.

  9. Turn on Unified Inbox.

    In Mailbird, go to Settings → Accounts, then enable the Unified Inbox. Confirm that “Unified Inbox” appears and shows messages from more than one account.[4]

  10. Send a test message from each account (and verify the “From” address).

    Compose a new email, pick the correct From address, and send it to another address you own. Then reply from the receiving account and confirm the reply comes from the expected sender.

  11. Unlink Gmailify after you verify Mailbird is working.

    Open the Gmail app → settings → Gmailify/linked account → Unlink. Choose whether to keep the already-synced copies in Gmail for search/history.[2]

  12. Remove duplicate delivery paths and set a reminder to re-check later in 2026.

    Pick one “source of truth” for new mail (direct IMAP in Mailbird is usually simplest). If you see duplicates, disable forwarding or remove the extra account connection. Then set a calendar reminder to confirm none of your workflows still depend on Gmailify/POP during the full turn-down later in 2026.[1]

Why this works

Gmailify relied on Gmail acting as the middle layer for other providers. During the Gmailify sunset, the safest move is to connect to each mailbox directly (IMAP/OAuth), then use a unified inbox to recreate the “everything in one place” workflow on desktop—without waiting for Gmailify to break.[1][4] If you’re comparing long-term setups, reviewing Gmail alternatives can help you choose a workflow that doesn’t depend on Gmail as a middle layer.

Troubleshooting

Symptom Likely cause Fix
“Try Gmailify” / “Link account” is missing in the Gmail app. The provider isn’t eligible, or Gmailify setup is disabled during the 2026 phase-out. Skip Gmailify and connect the account directly in Mailbird via IMAP (or keep it as a standard IMAP account in the Gmail app).[1][2]
Your third-party inbox stopped updating inside Gmail on desktop. Gmail’s POP-based “Check mail from other accounts” is being removed. Connect directly to the provider with IMAP in a desktop email client, or set up provider-side forwarding if that fits your workflow.[1]
Mailbird shows “Authentication failed” when adding Gmail. Gmail sign-in is being attempted with username/password or blocked by security/VPN. Re-add the account and use OAuth 2.0 / “Sign in with Google,” then retry with VPN disabled.[3][7]
Gmail keeps asking for your password repeatedly in an email client. The client/version doesn’t complete OAuth correctly. Update the client, remove the Gmail account, and add it again using “Sign in with Google.”[3]
You get a “Too many simultaneous connections” error for Gmail. Gmail allows up to 15 email clients connected at once per account. Sign out of extra clients/devices, remove duplicate setups, then try again.[3]
Your non-Gmail provider rejects the password even though webmail works. 2-step verification is enabled and the provider requires an app password for IMAP/SMTP. Create an app password in the provider’s security settings and use that in Mailbird instead of your normal password.[7]
Replies send from the wrong address in a unified inbox. The wrong “From” identity is selected during compose, or identities aren’t set up. Before sending, pick the correct From address; if needed, add identities and test each one.[4][5]
You see duplicates (or missing messages) after switching. Forwarding + IMAP are both active, or you’re looking at Gmailify copies vs originals. Pick one delivery path. If you keep Gmail copies, remember changes to those copies may not sync back to the original provider.[2]

Variations

  • Mobile-first: Keep the third-party account inside the Gmail app using IMAP (even without Gmailify features) and use Mailbird only on desktop.
  • Forwarding-first: Set up automatic forwarding at the original provider so mail lands in a single Gmail inbox (useful if you truly want Gmail to be the only inbox you check).
  • Two unified inboxes: Use Mailbird’s Unified Inbox for “work + bills,” but keep low-priority accounts separate so they don’t distract you.
  • Send-as only: If you only need to reply from an old address (not read its whole inbox), create an identity rather than adding a full IMAP account.[5]

Google’s own guidance during the change highlights forwarding and adding the account in the Gmail app (IMAP) as the two main ways to keep accessing third-party mail via Gmail.[1]

Make-ahead / backup / storage / scaling

Make-ahead (10 minutes that saves headaches)

  • Screenshot your current Gmailify/linked account screens before you unlink anything.
  • Write down which address receives password resets for each account (recovery email/phone).
  • Send yourself a “baseline” test email to each address now, so you can compare delivery after migration.

Storage

  • If you previously linked accounts into an existing Gmail inbox, keep an eye on your Google storage—linked accounts can contribute to storage use.[2]
  • If you keep Gmail copies when unlinking, treat them as an archive copy—your original mailbox remains the source of truth.

Scaling (adding more accounts later)

  • Add the account in Mailbird once, verify it syncs, then decide whether it belongs in Unified Inbox.
  • Unified Inbox only appears after you’ve added more than one account, so add your accounts first, then enable it.[4]

Frequently Asked Questions

Is Gmailify being discontinued? — Yes, phased out

Yes. Google has confirmed Gmailify is being phased out during 2026, with new setups ending by the end of Q1 2026 and existing connections turned down later in 2026.[1]

Can I still set up Gmailify right now? — Maybe, during phase-out

Maybe. During the phase-out, some accounts may still show Gmailify options while others won’t. If you don’t see “Try Gmailify” or “Link account,” treat that as expected and move to an IMAP-based setup.[1][2]

Will I lose emails that already synced into Gmail? — No, can remain

No. Messages that were already synced into Gmail can remain there. You can also choose whether to keep copies in Gmail when you unlink a Gmailify connection.[1][2]

What’s the difference between Gmailify, POP, and IMAP (in plain English)? — Linked certain third-party

Gmailify linked certain third-party accounts into Gmail with extra Gmail-style features. POP is an older “download mail” method used by Gmail’s “Check mail from other accounts.” IMAP is a syncing method used by many email apps (including Gmail mobile and desktop clients) to keep folders in sync across devices.[1][2]

Why do I see “Gmailify is not available for this provider”? — Provider isn’t eligible

Gmailify only supported certain providers/accounts to begin with, and the feature is also being phased out. If your provider isn’t eligible (or the rollout has already reached your account), you won’t be able to link it.[1][2]

Can I manage multiple Gmail accounts in one desktop inbox? — Yes, unified inbox

Yes. Add each Gmail account to a desktop client that supports “Sign in with Google,” then use a unified inbox view to read and search across accounts from one place.[3][4]

Do I need an app password for Gmail in a desktop email client? — Usually not

Usually not. When available, “Sign in with Google” (OAuth) is the preferred method. App passwords can still exist for some cases, but they’re generally not needed if OAuth works.[3]

Does unlinking Gmailify delete my original inbox at Yahoo/Outlook/etc.? — No, remains intact

No. Unlinking stops Gmail from showing new messages from that provider. Your original mailbox remains intact at the original provider.[2]

Quick checklist (screenshot this)

  • Listed every account I need (including multiple Gmail accounts)
  • Confirmed whether Gmailify is currently linked (screenshot saved)
  • Signed into each original mailbox in a browser (recovery info updated)
  • Enabled IMAP (and generated any needed app passwords) for non-Gmail providers
  • Added each Gmail account to Mailbird using “Sign in with Google”
  • Added each non-Gmail account to Mailbird using IMAP
  • Enabled Unified Inbox and verified I can see mail from at least two accounts
  • Sent test emails from every account and verified the “From” address
  • Unlinked Gmailify (after verifying Mailbird is working)
  • Removed duplicate delivery paths (forwarding / extra imports)
  • Added a calendar reminder to re-check during the 2026 turn-down window

If you regularly manage multiple inboxes, using a Gmail desktop client with a unified inbox is the most stable long-term replacement for Gmailify.
