7 Best Clean Email Alternatives in 2026
Clean Email is one of the better known inbox cleanup tools, and for good reason: it works with almost any mailbox, groups email into sensible bundles, and has been around long enough to be stable. It also costs $9.99 a month for one account, and it does its analysis on its own servers. Those two facts are why most people go looking for an alternative.
This roundup compares seven options on the things that actually decide the choice: price, where your email gets processed, whether there is a free tier you can keep, and how well each handles Gmail. I build one of these tools (MailMop), so read the MailMop section with that in mind. The pricing for every tool was checked against its own site on the day of writing.

Why people leave Clean Email
Before the list, it helps to be precise about what Clean Email does and does not do, because it is not a bad product.
- Price. $9.99 a month, or $29.99 a year, for one mailbox. Five accounts is $49.99 a year, ten is $99.99. For a single Gmail account that is on the high side for a tool most people use twice a year.
- Server-side processing. Clean Email connects to your mailbox from its servers. It says it only analyzes headers, never downloads full messages, keeps data for 45 days, and does not sell it. That is a reasonable policy. It is still your mailbox metadata sitting on someone else's infrastructure, which is the thing a growing number of people want to avoid entirely.
- More than most people need. Smart folders, auto-clean rules, a screener, multiple providers. If you have one Gmail account and want to clear it out, most of that is surface area you will never use.
If none of those bother you, Clean Email is fine. If any of them do, here are the alternatives.
1. MailMop
Best for: Gmail users who want the analysis done in the browser, a free tier, and a low annual price.
MailMop connects to Gmail through Google's official API and does everything in your browser tab. Nothing about your email is uploaded to a server. It scans the inbox and returns one table of every sender ranked by how many emails they have sent you, with the date of their last email and an unread filter. From that table you delete a sender in one click, delete with exceptions (keep specific emails), unsubscribe, block with an auto-created Gmail filter, mark as read, or apply a label, and you can select many senders and act on them together.
- Price: free tier, Pro is $22.68 a year ($1.89 a month, billed annually). One plan, no per-account tiers.
- Privacy: browser-side processing, message contents never stored. The code is open source and the app passed Google's CASA security assessment, which Google requires for apps that access Gmail data.
- Limits: Gmail only. Large inboxes take a while to analyze because the work happens on your machine (about ten minutes for 25,000 emails), though results appear as it goes.
- Honest downside: it is a smaller, newer project than Clean Email. No smart folders, no multi-provider, no auto-clean rules beyond Gmail filters.

2. Mailstrom
Best for: people who want Clean Email's multi-provider model with a different interface.
Mailstrom is the closest like-for-like alternative. It connects over the server side, groups email by sender, subject, time, size, and social network, and supports Gmail, Outlook, Yahoo, and IMAP mailboxes. Its "Chill" and "Expire" features (mute a sender for a while, or auto-delete their mail after a set period) are genuinely useful.
- Price: Basic is $9 a month or $59.95 a year for one account, capped at 10,000 emails. Plus is $14 a month or $99.95 a year for three accounts and up to 250,000 emails. Pro is $29.95 a month or $199.95 a year. No free plan, a free trial to start.
- Privacy: server-side, like Clean Email.
- Watch out for: the 10,000 email cap on Basic. Most inboxes that need cleaning are past that, which pushes you to the $99.95 tier.

3. Leave Me Alone
Best for: unsubscribing across several accounts at once, with a company that has been vocal about not selling data.
Leave Me Alone focuses on subscriptions. It scans your accounts, lists every mailing list, and unsubscribes with one click. It also has a screener for new senders, a spam blocker, and "rollups" that bundle newsletters into a digest. It has positioned itself for years as the anti-Unroll.Me, and its site states it does not store email content except what is needed to build rollups.
- Price: 10 unsubscribes free, then a $19 seven-day pass, or monthly and yearly subscriptions for 4 or unlimited accounts (check their pricing page for current rates). 14-day refund policy.
- Privacy: server-side, with a stated no-sell, no-store-content policy.
- Watch out for: it is an unsubscribe tool first. Bulk deleting years of old email from a sender is not the focus.

4. Trimbox
Best for: Gmail users who want a browser extension with on-device processing.
Trimbox is a Chrome extension (with mobile versions) that identifies mailing lists in Gmail and lets you unsubscribe or mass delete a sender's old emails without opening them. Its site says emails never leave your device and that it has been through Google's privacy review.
- Price: a free tier with paid upgrades. Trimbox does not publish prices on its homepage, so check inside the extension.
- Privacy: on-device, per their claims.
- Watch out for: extension-based tools depend on Gmail's web interface and can break when Google changes it. Pricing transparency is weak.

5. InboxPurge
Best for: a cheap Chrome extension that keeps processing local.
InboxPurge is a Gmail-only Chrome extension. It groups email by sender, bulk deletes, and unsubscribes, and states that your emails never leave your browser and that data is not sold or shared.
- Price: a free tier, a $5 seven-day pass, or Pro at $7 a month or $48 a year. One license covers unlimited Gmail accounts. 14-day money-back guarantee.
- Privacy: browser-side.
- Watch out for: desktop Chrome only. There is no mobile route.
6. Unroll.Me
Best for: people who want something free and do not mind how it is paid for.
Unroll.Me is the tool most people have heard of. It lists your subscriptions, unsubscribes in one click, and rolls newsletters into a daily digest. It is free and supports Gmail, Outlook, Yahoo, AOL, and iCloud.
The catch is the business model. Unroll.Me is owned by Nielsen Consumer, a market research company, and its Data Usage page explains that anonymized purchase information from your inbox is used for market research. That is how it stays free. In 2017 it emerged that the company's previous owner had sold Lyft receipt data from users' inboxes to Uber, which is the story most people remember. It has been more transparent since, but the model is the same: your inbox is the product.

7. Gmail's own tools
Best for: anyone who does not want to connect a third-party app at all.
Gmail can do a surprising amount of this on its own if you know where to look:
- Manage subscriptions (left sidebar, under More) lists senders with the most recent bulk mail and offers a one-click Unsubscribe for each. See how it works, and what to do if it is not showing.
- Search operators plus the "Select all conversations that match this search" link delete thousands of emails at once.
from:sender,category:promotions older_than:1m, andlarger:10Mcover most of a cleanup. Our complete Gmail cleanup guide walks through it. - Filters delete or archive future mail from a sender on arrival.
What Gmail does not give you is the ranked list of who fills your inbox, which is the thing every tool above is really selling. If you are willing to guess senders and search for them one at a time, it is free and needs no permissions.
A note on self-hosted options
If you are technical and want to run something yourself, there are open-source Gmail cleanup scripts on GitHub that run locally against the Gmail API. They are free and keep everything on your machine. The cost is setup: you create your own Google Cloud project, configure OAuth credentials, and run the tool from a terminal. For most people that is more work than the cleanup itself, but it is the right answer for the self-hosting crowd.
How to choose
- You only use Gmail and privacy is the reason you are switching: MailMop, InboxPurge, or Trimbox. All three keep processing on your side. MailMop is the only one of the three that is open source with a CASA assessment, and the only web app (so it works on a phone browser).
- You need Outlook, Yahoo, or iCloud in the same tool: Mailstrom or Leave Me Alone. Both are server-side, like Clean Email, so you are choosing on price and features rather than privacy.
- You want free and do not care how it is funded: Unroll.Me, with eyes open about the data model.
- You want nothing connected to your account: Gmail's own search, filters, and Manage subscriptions.
If you want to see what a sender-ranked view of your inbox looks like before deciding, MailMop is free to try and takes a few minutes to run.
