Summary: Both Clean Email and Mailstrom support multiple email providers and accounts, enabling users to reply to and forward emails directly within the platform. They are available in the EU and EEA, ensuring compliance with privacy regulations. Neither service shares user data with third parties for advertising, prioritizing user privacy and security while offering reliable inbox management tools.
Similar Features With Varying Functionality
Both services offer a basic set of functionalities, but let's dive deeper to explore the differences — spoiler: Clean Email can do much more.
The key difference to highlight is the Unsubscribing feature:
✅ Mailstrom: allows one-click unsubscribing from mailing lists, but only when an unsubscribe address is available. If such an address doesn’t exist, the option to unsubscribe via the sender’s website in a new tab is provided, putting the work back on you. It's also important to note that Mailstrom only permits unsubscribing from one subscription at a time.
✅ Clean Email: automatically unsubscribes you by sending requests and completing unsubscribe forms. If the sender doesn’t comply, Clean Email will still automatically delete future emails from that sender for extra protection. Unlike Mailstrom, Clean Email improves its form-handling capabilities, so you won’t need to manually fill out anything. The app also allows you to opt out of multiple subscriptions at once.

Yes, Mailstrom is a legitimate and safe tool for managing your inbox. It uses OAuth authentication, which keeps your email credentials secure.
Here’s how it works:
- Data Collection: The service gathers only the basics, such as your email address and a few non-personal details like your IP address. This information helps the system work properly and improve over time.
- Data Usage: Mailstrom uses this data to refine its features and may share it with a few trusted third parties who help deliver specific services. The purpose is functionality, not marketing or advertising.
- No Selling: Mailstrom does not sell your information or use it for ads. If you want to know more, you can read their privacy policy, which explains everything in plain language.

Is Clean Email Safe?

Key Differences Between Mailstrom and Clean Email
While Mailstrom and Clean Email may seem similar, there are key differences in functionality.
Blocking
- Mailstrom provides a one-click Block option for individual senders but doesn’t automatically block new addresses from the same domain. You will need to manually block new senders from the same domain.
- Clean Email allows you to block entire domains, including future emails from new addresses, and supports blocking multiple domains at once within a single email rule.
Why do I need this? Spammers often change email addresses within the same domain to bypass filters. Clean Email’s robust blocking prevents future spam from these sources.
Unsubscribing
- Mailstrom’s unsubscribe feature is quite limited. It only works when an unsubscribe link is actually present, and there’s no bulk option available. This means you have to unsubscribe one email at a time, which can be tedious if your inbox is overflowing.
- Clean Email, on the other hand, supports bulk unsubscribing and automatically blocks future emails from senders who ignore your unsubscribe request. It’s a much smoother and faster experience.
Unlike Mailstrom, Clean Email’s Unsubscriber tool can even handle cases where no unsubscribe link exists. It takes care of that for you. On top of that, it comes with a few extra features that make managing subscriptions easier:
- Pausing a Subscription: You can temporarily stop emails from certain senders and decide later when you want to receive them again.
- Unsubscribing in Bulk: With one click, you can opt out of multiple mailing lists at once, saving yourself a lot of time.
If you’d rather keep some emails but still maintain control, Clean Email gives you options for that too:
- Move to Read Later: You can send messages from specific senders to a Read Later folder, so they’re out of sight until you’re ready to deal with them.
- Keep the Newest: This feature lets you keep only the most recent message from a sender, automatically deleting older ones to help keep your inbox organized.
Message Filtering & Automation
Mailstrom offers some filtering options, but they’re fairly basic:
- Filters by: size, sender, subject, or date.
- Pre-defined filters: Shopping, Social, Mailing lists, and People I’ve emailed.
- Automation: Can only move messages from specific senders to folders.
Clean Email goes much further with both filtering and automation:
- Organizes messages into 33 Smart Folders, including Social notifications, Finance and Insurance, Entertainment, Unread emails, Travel, and more.
- Advanced filters: size, date, sender, read/unread, labels, and more.
- Automation: Apply rules like delete, archive, label, move, or mark as spam for future emails.
Platforms
Mailstrom is mainly a web-based tool, but it does have iOS support through a separate app called Chuck. That means you might end up switching between different apps depending on your device, which can feel inconvenient.
📌 Discover Clean Email’s edge as a versatile Chuck Email alternative.
Clean Email provides a comprehensive experience across platforms:
- Available on web, macOS, iOS, and Android
- Seamless multi-platform support ensures consistent functionality across all devices

How to Get Started with Clean Email after Mailstrom
If you’re ready to try Clean Email out as a Mailstrom alternative, here’s how to get started:
Step 1. Go to: https://app.clean.email/
You can get started with Clean Email for free and instantly use it to transform a messy inbox into a neatly organized collection of email messages.
Step 2. Sign in with your email account.
Clean Email works with any IMAP email services, including Gmail, Outlook, iCloud, Yahoo Mail, and others.
Step 3. Begin with the Cleaning Suggestions feature for an effective start to decluttering your inbox.
Clean Email’s Cleaning Suggestions are like a helpful assistant that knows what to tidy up before you even ask. It scans your inbox, spots the types of emails that are cluttering things up, and suggests actions such as archiving or deleting them. You can accept or decline these suggestions with just a click.
If you find that you’re handling the same types of messages over and over, you can also turn those suggestions into Auto Clean rules. Once set, they’ll automatically manage similar emails in the future, so your inbox stays organized without much effort on your part.
Step 4. Check out the Unsubscriber tab for detaching from unwanted mailing lists with just one click.
Unsubscriber helps you break free from unwanted mailing lists with a single click. It automatically sends an unsubscribe request for you and, if the sender ignores it, Clean Email will block future messages from them.
You can also delete all past emails from that sender in one go. If you prefer a softer approach, there’s an option to pause a subscription instead of removing it entirely or to redirect those emails to another folder. It’s a good balance between control and flexibility, depending on how you like to manage your inbox.
Step 5. Explore the Smart Folders to manage emails based on specific criteria they have.
This is where Clean Email really shines. They group your messages by category, pulling together everything from social notifications and travel confirmations to shopping receipts and financial statements.
You’ll see a familiar inbox-style layout but with clear groups, filters, and sorting options that make navigation quick and easy. It’s designed to help you find what matters faster while keeping your inbox tidy in the background.
