SpamSieve alternatives for Mac mail

The best SpamSieve alternative for Mac is Alrighty if you use iCloud, Gmail or Outlook and want more than a spam filter: it checks new mail for phishing on your Mac, lists the scams and cold senders that got through, and ends a sender's mail in one action. If you only want spam gone for free, Apple Mail's junk filter and your provider's own filter already run. Clean Email and SaneBox work on their own servers, so they keep going while your Mac sleeps. Canary Mail adds phishing protection on Mac, iPhone, Windows and Android.

Most lists of SpamSieve alternatives are directory pages. They put Windows tools such as MailWasher next to Mac apps and don't say which ones you can install on a Mac today. They also skip the question that decides most switches: does the tool still filter when your Mac is asleep or closed? This page answers that for each pick, and says what each one does with mail that isn't spam but that you still don't want.

How we checked

We read each vendor's own product, help, pricing and privacy pages on November 4, 2026. Every fact about another product links to its source, and where a page didn't say something, we say so. We compared price, the accounts each tool works with, where it filters, whether it needs your Mac to be on, and what it does with mail that a spam filter doesn't catch, such as cold sales pitches and newsletters. We did not test the tools. Alrighty is our app, and it's listed first.

Why people look for a SpamSieve alternative

SpamSieve is a well-liked filter, and many people keep it for years. They look for something else when one of its limits starts to matter. Each of these is a fact from C-Command's own pages:

• It needs your Mac and your mail app running. SpamSieve filters from inside your mail app on the Mac. Its manual says "your mail program needs to be running on your Mac," and the Mac must be on or set up to filter during Power Nap (C-Command).
• There's no iPhone app. "There is not currently an iPhone version of SpamSieve." Your Mac filters the inbox, and IMAP or Exchange sync removes the spam from your phone, but only when the Mac has run first.
• New Outlook doesn't work with it. SpamSieve talks to Outlook through AppleScript, which works only in legacy Outlook. Our spam filter for Outlook guide has the details.
• It filters spam only. A newsletter you signed up for, or a sales pitch from a real company, isn't spam to a Bayesian filter. SpamSieve has no unsubscribe tool and no list of cold senders.

If none of these bothers you, SpamSieve is a good filter, and our spam blocker guide explains how it compares with the filters already on your Mac.

Alrighty: best for stopping spam, scams and cold mail in one Mac app

Alrighty is a mail app that puts iCloud, Gmail and Outlook accounts in one inbox, on Mac, Windows and Linux. It isn't an add-on for Apple Mail, so it replaces your mail app instead of filtering for it. Your provider's spam filter still runs first. Alrighty works on what gets past it.

• Phishing checks. New mail is checked for phishing on your Mac, with no server call. A message that is sure to be phishing goes to Junk. A likely one stays in your Inbox with a warning.
• Stop mail. One action ends a sender's mail. It unsubscribes every way the message offers (one-click, email, or the list's web page), archives their mail, and moves new mail from them out as it arrives. It unsubscribes only from senders whose mail passed DMARC and wasn't marked spam, so a scammer never learns your address is live.
• Clean up. It lists the senders you likely don't want, such as scams, cold outreach and newsletters you never open, so you can stop them all at once.
• Filters. These stop a kind of mail that comes from a new sender each time, like cold sales, which a block or a Bayesian filter can't catch. You describe the mail in your own words or set rules, and new Inbox mail that fits moves to Archive before the list shows it. Mail from people you wrote to, or in a conversation you wrote in, is never moved. Our guide to stopping cold emails explains why this mail gets past spam filters.

Price. A 14-day trial with no card, then a Free plan or Pro.

Where it filters. Phishing checks and rule filters run on your Mac. Your mail stays with iCloud, Google or Microsoft, and Alrighty keeps its copy and search index on your Mac. Some parts use Alrighty's server, signed in only. A filter you describe in words asks an AI model through it; if the AI doesn't answer within 5 seconds, the mail stays in your Inbox. Clean up sends each sender's address, three facts the receiving server found, and up to 3 of their newest emails (2,000 characters each) to Alrighty's server, which asks a model to sort them. Signed in, Clean up sorts senders in the background, and opening a reply starts a suggested draft. Signed out, nothing goes to Alrighty's server.

What it can't do. There's no iPhone app, so like SpamSieve its checks run on your Mac. It takes iCloud, Gmail and Outlook accounts only, not Yahoo, AOL, Fastmail or other IMAP. It has no calendar. It's new, with no long track record. See everything Alrighty does.

Pick it if you want spam, scams, cold mail and old newsletters handled in the app you read mail in, and you're ready to leave Apple Mail.

Apple Mail junk filter: best free alternative if you stay in Apple Mail

Apple Mail has a junk filter built in. To turn it on, choose Mail > Settings, click Junk Mail, and select Enable junk mail filtering (Apple). Like SpamSieve, it learns: Apple says "Each time you confirm a message as junk or not junk, the junk mail filter improves."

Beyond spam. Mail shows an Unsubscribe banner on mailing-list mail, and Block Sender takes up to 3,000 addresses. The steps for blocking are on our block a sender page.

Where it filters. On your Mac, in Mail, so it has the same limit as SpamSieve: it filters when Mail runs.

What it can't do. Apple's junk mail page describes no phishing warning. The filter has no list of the cold senders that got through, so you find them one at a time.

Pick it if SpamSieve was more filter than you needed, and your provider already catches most spam.

Your provider's filter: best free alternative that works with your Mac off

iCloud, Gmail and Outlook.com each filter spam on their own servers before mail reaches any app. This is the one filter that keeps working with your Mac closed, and it covers your iPhone too. SpamSieve's own page says you can use it "instead of or in addition to your mail provider's junk filter" (C-Command), so the provider's filter is already the first layer.

How to make it stronger. Report spam instead of deleting it, so the filter learns. Mark good mail as not spam. Add server-side rules on iCloud.com, in Gmail or in Outlook.com for a domain that keeps coming back. Our guide on how to stop spam emails has the steps for each provider, and which kind of spam each step stops.

What it can't do. Each account learns on its own, so with three accounts you report in three places. A provider's filter guesses from the message, so cold sales mail from a real domain often gets through. It doesn't unsubscribe you.

Pick it if you want filtering that never depends on your Mac, at no cost.

Clean Email: best for screening new senders on the server

Clean Email connects to your mailbox from its own servers, so it works no matter which app you read in and while your Mac is off. Its Screener "intercepts messages from new senders and safely holds them in quarantine for your review" (Clean Email). You choose what it holds: mailing lists, automated messages, or people writing for the first time.

Beyond spam. It sends unsubscribe requests for you and can block lists that ignore them. Its Auto Clean rules act on new mail, such as archiving social notifications (Clean Email).

Accounts and apps. The Screener page names Gmail, Yahoo, Outlook, AOL, iCloud and any IMAP service. Clean Email runs on iPhone, iPad, Android, Mac and the web.

Where it filters. On Clean Email's servers, which index your mail's "sender and recipient details, subjects" and other metadata. Its policy says it doesn't read message bodies, but fetches them to show full previews (privacy).

What it can't do. Its pages describe screening, unsubscribing and rules, not a filter that learns from your mail like SpamSieve, and they make no phishing claims. One more company has standing access to your mailbox. Its plans page showed no prices when we read it. Our Clean Email alternatives page covers its cleanup tools.

Pick it if you want new senders held for your OK on every device, and you keep Apple Mail.

SaneBox: best for pushing unwanted senders aside in every app

SaneBox is a service, not a mail app. It moves mail into folders in your own mailbox, so the result shows in Apple Mail, on your iPhone and on the web, whether your Mac is on or not. It reads less than most services: "We only access the envelope and header data associated with your emails" (privacy).

Beyond spam. Drag a message to @SaneBlackHole, and SaneBox learns "to always send future emails from that sender straight to SaneBlackHole." It moves them to your Trash after 7 days (help).

Price. Plans "start at just $7 per month, with significant savings for annual subscriptions" (SaneBox). There's no free plan.

What it can't do. SaneBox sorts by importance. Its pages we read don't describe a spam or phishing filter, so it doesn't replace what SpamSieve does on its own. Its optional AI features "may now process the body content of your emails." Our SaneBox alternatives page compares it with the apps that replace each folder.

Pick it if spam isn't your real problem, low-priority mail is, and you want it sorted on every device.

Canary Mail: best for phishing protection on Mac and phone

Canary Mail is a mail app for Mac, iPhone, iPad, Windows and Android. Its Pro+ plan "adds end-to-end encryption with PGP and SecureSend, plus phishing and impersonation protection" (Canary). Unlike SpamSieve, it has apps on your phone.

Price. The free plan has unlimited accounts and 1-Click Unsubscribe. Pro+ is $100 a year, and Canary has no monthly billing (pricing).

Where it filters. Its security page doesn't say whether the phishing scan runs on your device or on Canary's servers. Its privacy policy says account details stay on your device, except that push notifications "temporarily store your email address, credentials, sender, subject line" on its server (privacy).

What it can't do. Phishing protection is only on Pro+. Its pages don't describe a learning spam filter like SpamSieve's, a block list, or a list of cold senders.

Pick it if phishing is what worries you and you want one app on your Mac and your phone.

What about MailWasher?

MailWasher shows up on most SpamSieve alternative lists, but it doesn't run on a Mac. Its download page answers "Is there a Mac version? Not currently. MailWasher Pro is Windows-only" (MailWasher). Our MailWasher alternatives page lists the Mac tools that do its job, which is to check mail on the server before it reaches your apps.

How to choose

• Spam, scams, cold mail and old newsletters handled in one Mac app, with iCloud, Gmail or Outlook: Alrighty.
• Free, and you stay in Apple Mail: Apple Mail's junk filter.
• Filtering that works with your Mac off, at no cost: your provider's filter. Report what it misses.
• New senders held for your OK on every device: Clean Email.
• Low-priority mail sorted in every app, for a monthly fee: SaneBox.
• Phishing protection on your phone too: Canary Pro+.
• A stronger Bayesian filter that sends nothing anywhere: keep SpamSieve. Our Apple Mail plugins guide covers it and the other add-ons that still work.

Questions

Is there a free alternative to SpamSieve?

Yes. Apple Mail's junk filter is free and learns from each message you mark. Your provider's filter is free too, and it runs on the server, so it works with your Mac off. Alrighty has a Free plan after its 14-day trial.

Does SpamSieve work on iPhone?

Not directly. C-Command says "there is not currently an iPhone version of SpamSieve." Your Mac filters the inbox, and IMAP or Exchange sync removes the spam from your phone. That works only when your Mac and your mail app have run first.

Does SpamSieve work with the new Outlook for Mac?

No. SpamSieve uses AppleScript to talk to Outlook, which works only in legacy Outlook. If you use the new Outlook, the filter on Microsoft's servers is the one that runs. Our spam filter for Outlook guide covers the other options.

Why does SpamSieve miss cold sales emails?

A Bayesian filter learns what spam looks like from your mail. A cold pitch is often written by a real person or a sequence tool, sent from a real domain, so it looks like normal mail. A screener, a filter you describe in words, or a list of unwanted senders catches it better.

Can I use SpamSieve and my provider's filter together?

Yes, and C-Command suggests it. The provider's filter runs first on its servers, and SpamSieve then judges what got through on your Mac. SpamSieve can also rescue good mail that the server filter caught.
