Mimestream alternatives for iCloud and Outlook
Mimestream is a great Gmail app, but it only does Gmail. When you add an iCloud or Outlook account, these Mac mail apps take all three.
By Emmett Miller
The best Mimestream alternative is Alrighty if you have iCloud or Outlook accounts next to Gmail and want them in one inbox with less junk. Apple Mail is the free choice, Outlook fits Microsoft 365 work accounts, and Spark or Canary suit people who want the same app on their phone. If you're on Gmail and Microsoft 365 at work and price isn't a concern, Superhuman is the fast option.
Most people look for a Mimestream alternative for one reason: it works only with Gmail. Its own site says it's "Optimized for Gmail" and its pricing lists "All your Google accounts" (Mimestream). It's an excellent app for that job. When an iCloud or Outlook account shows up, you need a different one.
How we checked
We read each app's own pricing, help and privacy pages on November 2, 2026, and every fact links to the page it came from. We compared what matters when you leave Mimestream: which accounts each app takes, what it costs, where it processes your mail, and whether it keeps what Mimestream does well, a native Mac app that keeps your mail on your Mac. Alrighty is our app, and it's listed first.
What Mimestream does well
It's worth knowing what you'd give up:
- Native and private. Mimestream "only stores your data and tokens on your device" and connects "directly to the Gmail API, without going through any intermediary sync service" (Mimestream).
- Real Gmail. Labels, categories and Gmail search work the way they do on the web, because it uses "the full power of Gmail-backed search."
- Several Gmail accounts, in a unified inbox or kept separate.
- Price. $49.99 a year for up to five devices, after a 14-day trial with no credit card (pricing).
What it doesn't do: add iCloud, Outlook, Yahoo or any other non-Google account, or run on Windows. The iPhone and iPad app is in beta.

Alrighty: best when Gmail isn't your only account
Alrighty is a mail app for Mac, Windows and Linux that takes Gmail, iCloud and Outlook accounts in one inbox. Gmail signs in with Google, through the Gmail API, the same way Mimestream connects. iCloud uses an app-specific password, and Outlook signs in with Microsoft.
- Search that finds what you remember. Type it in your own words. "When is my flight" finds the airline's confirmation even though it never says "flight". Search runs on your Mac, across all your accounts at once, and you can ask a question and get the answer with the emails it came from.
- Stop mail. One click ends a sender's mail for good. Alrighty unsubscribes in every way the message offers, moves their mail out of your inbox, and keeps their new mail out too.
- Clean up. It lists the senders you probably don't want, such as scams, cold outreach and newsletters you never open, so you can stop them all at once.
- Your AI works in your mail. Claude, ChatGPT's desktop app, Codex, Cursor or a local model can read and search your mail, and can work in a window you watch. Nothing sends until you click Send. This link to your AI is off until you turn it on with Connect AI.
Where your mail goes. Like Mimestream, Alrighty keeps your mail and its search index on your Mac, and your sign-ins stay on your Mac, encrypted with a key from your system's keychain. AI features send only the emails they need to Alrighty's server, which passes them to an AI model (OpenAI's for answers and replies).
Price. A 14-day trial with no card, then a Free plan or Pro.
What it can't do. It has no iPhone app, and it adds Gmail, iCloud and Outlook accounts only.
Pick it if you liked Mimestream's native, private feel and now have an iCloud or Outlook account too.
Apple Mail: best free option
Apple Mail comes with your Mac and adds "iCloud, Gmail (Google), Exchange, school, work, or other" accounts (Apple). On macOS 27 it sorts mail into categories, lets you unsubscribe "directly in Mail," blocks up to 3,000 senders, and searches "based on what you mean, not just the words you type" (Apple).
What you give up from Mimestream. Apple Mail isn't built around Gmail the way Mimestream is. Its search relies on the Spotlight index on your Mac. When that breaks, it misses mail you can see, and our Apple Mail search guide has the fixes.
Pick it if you want free and built in.
Outlook for Mac: best with a Microsoft 365 work account
Outlook is free on the Mac App Store and works with "Microsoft 365, Outlook.com (including Hotmail and MSN), Gmail, Yahoo! Mail, iCloud, IMAP, and POP accounts" (Mac App Store). Personal accounts are free with ads. Work and school accounts need a license from your IT administrator (Microsoft).
Pick it if your second account is Microsoft 365 at work and you want mail and calendar together.
Spark: best for every device
Spark runs on Mac, iPhone, Windows and Android, and takes IMAP, iCloud, Exchange, Outlook, Yahoo and Google accounts (Spark). The free plan has unlimited accounts. Plus is $99 a year and Pro is $199 a year (pricing).
What you give up from Mimestream. Privacy is the big difference. Spark says some features "require our server-side email processing to work," including push notifications, and for custom IMAP accounts its stored access token "is your email login and password" (Spark).
Pick it if you want the same app on your computer and your phone.
Canary Mail: best free unified inbox
Canary runs on Mac, iPhone, iPad, Windows and Android, and its free plan includes unlimited accounts and a unified inbox (pricing). Paid plans are $36 or $100 a year, and Canary also offers 1-Click Unsubscribe.
Where your mail goes. Canary says your data is "stored on your device and is never transferred to our servers," except for push notifications on iPhone and Android, where it "will temporarily store your email address, credentials" (privacy policy).
Pick it if you want a free app across several platforms.
Superhuman: best for Gmail plus Microsoft 365, if price is no object
Superhuman "is only able to support Google or Microsoft 365-hosted accounts as of now" (Superhuman). If your second account is Microsoft 365 at work, it covers both. If it's iCloud or a personal Outlook.com account, it doesn't. Starter is $25 per member a month and Business is $33, billed yearly (plans).
Pick it if you're on Gmail and Microsoft 365 for work, you send a lot of mail, and your company pays.
How to choose
- Gmail plus iCloud or Outlook, native and private, less junk: Alrighty.
- Free: Apple Mail.
- Gmail plus Microsoft 365 at work: Outlook, or Superhuman if speed matters more than price.
- The same app on your phone: Spark or Canary.
- Still only Gmail: stay with Mimestream.
