Key Takeaways
- Unlistr is no longer installable. As of our July 2026 testing, the "Install on Microsoft 365" button on Unlistr's own website leads to a Microsoft AppSource listing that no longer works, and the add-in can't be found or added from within Outlook.
- It appears unmaintained. Existing installations failed to load during our checks, there are no recent updates, and our attempts to reach Unlistr's support went unanswered.
- No official explanation exists. Neither Microsoft nor Unlistr's developer (J&H Web Technologies) has published a shutdown notice—so we can only report what we observed, not why it happened.
- Clean Email is the maintained alternative. It unsubscribes across Outlook and Gmail, Yahoo, iCloud, AOL, and any IMAP inbox, works on web, macOS, iOS, and Android, and is actively supported.
Is Unlistr Still Available in 2026?
⚠️ In short: no—not for new users. As of our latest testing in July 2026, Unlistr's website is still online and still advertises "100,000+ users," but the "Install on Microsoft 365" button leads to a Microsoft AppSource listing that no longer works, and the add-in can't be installed from within Outlook. Existing installations appear to have stopped loading, and the product shows no signs of active maintenance or support.
Here's exactly what we found when we checked:
- The Unlistr website (unlistr.com) loads normally and still promotes the Outlook add-in.
- The site's own "Install on Microsoft 365" button points to a Microsoft AppSource product page that returns an error rather than an installable listing.
- Searching Microsoft AppSource directly for "Unlistr" returns no active listing.
- For accounts that still have the add-in, the Unlistr panel failed to finish loading in our tests.
- There is no visible pricing page, update history, changelog, or working support channel, and messages we sent went unanswered.
We want to be precise here: neither Microsoft nor J&H Web Technologies has published any statement that Unlistr has been discontinued, and we don't know the reason its listing is gone. What we can say, based on first-hand testing, is that it is no longer something you can install or rely on. If you depend on it today, it's worth moving to a tool that's still supported—which is what the rest of this guide covers.
What Unlistr Did (and Where It Falls Short Now)
Unlistr was an unsubscribe app built specifically for Outlook on Microsoft 365. Once installed from Microsoft AppSource, it added an unsubscribe button to Outlook that scanned your mailbox, collected everything that looked like a subscription into a "subscription center," and let you opt out of the ones you didn't want with a few clicks. It also tried to avoid suppression lists and other malicious senders that abuse unsubscribe requests to confirm a live address, and it let you add multiple accounts and target folders.
On paper, that was a useful tool for Outlook users. The problem in 2026 is twofold. First, as covered above, it's no longer installable and appears unmaintained—which means no security updates and no support if something breaks. Second, even when it worked, Unlistr was Outlook-only. If you also use Gmail, Yahoo, iCloud, or AOL, it could do nothing for those inboxes, and its mobile apps are no longer available either. For most people, replacing a single-platform tool that has stopped working is a good moment to switch to something that covers every inbox and stays maintained.
Switching from Unlistr to Clean Email
Moving off Unlistr is straightforward, because Clean Email isn't an add-in you install inside Outlook—it's a dedicated app that connects to your mailbox directly. There's nothing to uninstall and no broken listing to work around. Here's what switching looks like:
- Connect your inbox.Sign in with your email account—Outlook on Microsoft 365, Outlook.com, Gmail, Yahoo, iCloud, AOL, or any IMAP service. You can connect more than one.
- Open the Unsubscriber. Clean Email finds your active subscriptions and newsletters and groups them together so you can see everything in one place.
- Unsubscribe in bulk. Opt out of anything you don't want in a couple of clicks—including emails without an unsubscribe link. You can also "Pause" a sender to keep the subscription but move its messages out of your inbox.
- Keep it clean automatically. Use Auto Clean rules so future messages from the senders you choose are archived, moved, or deleted the moment they arrive.
Unlike an Outlook add-in, this works on every device you own and every inbox you depend on. For a wider view of the category, see our comparison of the best unsubscribe apps.

With the right inbox cleaner, you'll be able to easily unsubscribe from emails on Outlook and other services and use the saved time for something more productive and enjoyable.
What Is Clean Email?
Clean Email is a dedicated inbox cleaner that helps you unsubscribe from unwanted mail, block senders, and keep every inbox organized—across all your accounts and devices. Where Unlistr was a single-purpose add-in locked to Outlook, Clean Email connects to your mailbox directly and does far more than opt you out of newsletters.
Its Unsubscriber gathers every subscription in one view and lets you leave mailing lists in bulk, including messages that don't include a working unsubscribe link. Its Auto Clean rules automate the repetitive part of inbox management—Delete, Archive, Move, and more—so incoming mail is handled the moment it arrives, without building complex filters. You can also block any sender without notifying them, move "read later" messages out of your inbox, and check your address against known data breaches with Privacy Guard.
Crucially, it works not only with Outlook on Microsoft 365 but with every major IMAP service—Gmail, Outlook.com, Yahoo, iCloud, AOL, Yandex, and more—on web, macOS, iOS, and Android. It's a freemium app, and all you need to get started is to sign in with your email account.
Verdict: Clean Email Is the Best Unlistr Alternative
Unlistr was a capable Outlook add-in, but in 2026 it's no longer installable and shows no signs of active support—which makes "which alternative do I move to?" the only question that matters. Clean Email is the natural answer: it covers everything Unlistr did for Outlook, extends it to Gmail, Yahoo, AOL, iCloud, and every other IMAP service, works on all your devices, and is actively maintained.
It's also, for the same reasons, the best Unsubscriber alternative, the best Unroll.me alternative, and a strong alternative to Leave Me Alone. But rather than take our word for it, the best way to decide is to try it on your own inbox.
Best Unlistr Alternative - FAQs
Is Unlistr still available in 2026?
Not for new users. As of our July 2026 testing, Unlistr's website is still online, but its "Install on Microsoft 365" button leads to a Microsoft AppSource listing that no longer works, and the add-in can't be found or installed from within Outlook. Neither Microsoft nor Unlistr's developer has published an official explanation, so we can only report what we observed: it is no longer possible to install or reliably use it.
Why won't Unlistr load or install?
The most common issue is that Unlistr's Microsoft AppSource listing no longer resolves, so the "Install on Microsoft 365" link fails and the add-in can't be added to Outlook. For accounts that still have it installed, the panel may fail to finish loading. This points to an unmaintained back end rather than a problem on your side. The reliable fix is to switch to an actively supported tool such as Clean Email.
Is it safe to keep using Unlistr?
Even if an existing Unlistr installation still opens, an unmaintained email tool receives no security or privacy updates and has no working support if something goes wrong. For anything that connects to your mailbox, we recommend using a tool that is actively maintained. Clean Email is a supported alternative that works across all your accounts.
How do I switch from Unlistr to Clean Email?
There's nothing to migrate. Because Clean Email connects to your mailbox directly instead of installing inside Outlook, you simply sign in with your email account, open the Unsubscriber to review your active subscriptions, and unsubscribe in bulk. It works with Outlook on Microsoft 365 as well as Gmail, Yahoo, iCloud, AOL, and any other IMAP service.
Does Clean Email work with Outlook and Microsoft 365?
Yes. Clean Email fully supports Outlook on Microsoft 365 and Outlook.com, so Unlistr users don't lose any coverage by switching. On top of Outlook, it also works with Gmail, Yahoo, iCloud, AOL, Yandex, and any IMAP-based email service, from a single app on web, macOS, iOS, and Android.
What is the best way to unsubscribe from emails on Outlook?
You have three main options. First, use the unsubscribe links included in most subscription emails. Second, use an Outlook add-in—though Unlistr, once a popular choice, is no longer installable. Third, and most reliably, use a universal inbox cleaner like Clean Email, which supports not just Outlook on Microsoft 365 but most other major email services as well, and stays maintained.
