The short version: iCloud, Gmail and an IMAP mailbox can share one inbox, but not inside Gmail anymore. The route that used to cover it, Gmail pulling mail from other accounts by POP, is being switched off, and iCloud never offered POP in the first place. What is left is forwarding, a mail client that speaks IMAP, or a feed that reads all of them. Here is what each one does and what it costs you in setup.
Why Gmail no longer does this for you
Gmail's web version cannot be relied on to collect other accounts any more. According to 9to5Google on January 23, 2026, Google is ending Gmailify and the POP based "Check mail from other accounts" feature, and mail imported earlier stays in place. Google's suggested replacements are the Gmail app on Android or iOS, which reads third party accounts over IMAP without the extra Gmailify features, and automatic forwarding from the other provider for the web.
When we opened Gmail's help page on October 20, 2026, it still described the POP import and named iCloud Mail as a provider you can use it with. Apple's own page, dated February 3, 2026, says iCloud Mail does not support POP. The two pages disagree, and the Gmail page itself says Google is making changes to Gmailify and POP support. Do not build a setup on the POP route.
Two limits from the same Gmail page matter if you stay in Gmail: you can add up to five email addresses, and only messages come across, not folders or labels. Outlook accounts cannot be added in Gmail on a computer at all, only through the Gmail app.
Three routes compared
Forwarding keeps everything in Gmail but replies from the wrong place, a mail client shows every account but ranks nothing, and a single feed ranks across accounts. The table shows what each route combines and what stays separate.
| Feature | What it combines | What stays separate |
|---|---|---|
| 1. One ranked feed (Nolario) | Gmail, iCloud and any IMAP mailbox in one list, ranked by score | Shared queues, sending on your behalf |
| 2. A mail client over IMAP | Several accounts in one app | Ranking: you decide what matters in each account |
| 3. Forwarding into Gmail | Incoming mail from the other provider | Replies from the old address, folders, history |
Route 1: one feed that reads every mailbox
A feed that connects to each account and scores the messages is the only route that tells you which one to open first. Nolario is our product, so weigh this pick accordingly. We rank it first because it connects Gmail and any IMAP mailbox, iCloud included, scores every message from 0 to 100 across all of them, and drafts replies in your voice, so a client's message in an old iCloud address is not buried under newsletters in Gmail.
The limits are plain. Nolario is a desktop web app, access is by waitlist, and it ranks and drafts but never sends for you. It has no shared queue, so it is not a team mailbox, as we explain in shared inbox vs unified inbox. For the general idea, see what a unified inbox is, and the integrations page lists what connects today.
Route 2: a mail client with several accounts
A mail client is the simplest route if you only need to see every account in one window. Apple's Mail guide says you can send, receive and manage email for all your accounts in one location on your Mac, and lists iCloud, Gmail, Exchange and other accounts as examples. The page does not say whether the inboxes merge into one list, so check that in the app you pick.
What a client does not do is decide for you. Every account still produces its own stream, and the message that needs you sits wherever it arrived. That is the gap our post on AI email assistants for IMAP and iCloud compares tool by tool.
Route 3: forward everything into Gmail
Forwarding is the cheapest fix and the one Google itself recommends for the web. Turn it on at the other provider, and new mail arrives in your Gmail inbox. You lose the old mailbox structure, and a reply goes out from your Gmail address unless you also set up sending as the old one. Mail from before the forward date stays behind.
Connect an iCloud mailbox over IMAP, step by step
Any tool that connects over IMAP needs the same four things: the server, your username, the port and an app-specific password. Do them in this order.
- Open your Apple Account, go to Sign-In and Security and create an app-specific password.
- Incoming server: imap.mail.me.com, port 993, SSL. Apple says to try TLS if you get an SSL error.
- Username: the part of your iCloud address before the @. If that fails, use the full address.
- Outgoing server, if the tool sends: smtp.mail.me.com, port 587, with your full iCloud address as the username and the same app-specific password.
- Paste the app-specific password, never your Apple Account password. In Nolario the iCloud preset fills the servers in once you type the address, so you only add the password.
All values are from Apple's iCloud Mail settings page, dated February 3, 2026, which we opened on October 20, 2026. Apple also says to use iCloud Settings on a device that meets its system requirements instead of a manual setup, so prefer that where it exists.
Which route for which mailbox set
If you have two or three accounts and one of them is busy, forward the quiet ones into Gmail. If you have iCloud, a work Outlook account and a domain mailbox, use a client or a feed, since Gmail cannot add Outlook on a computer. If your problem is not seeing the accounts but deciding which message matters, only a ranked feed helps, and our Outlook All Accounts view guide covers the Microsoft side of the same question.
Where Nolario fits
Nolario fits when you already have several mailboxes plus Slack or Teams and the problem is attention, not access. It does not fit if you need a shared queue for a team, a mobile app today, or something that sends mail on its own. In those cases a client or a team inbox is the better answer. The pricing page has the plans.
