You have thousands of emails you do not need. Old newsletters, expired promotions, shipping notifications from three years ago, and reply chains that stopped being relevant long before they stopped arriving. A clean email inbox is not just about aesthetics — it is about reclaiming your time, reducing stress, and making sure the messages that matter are not buried under the ones that do not.
Whether you call it email cleaning, inbox cleanup, or just getting things under control, the goal is the same: a manageable inbox that works for you instead of against you.
What Does "Clean Email" Actually Mean?
Cleaning your email means systematically removing, organizing, and managing messages so your inbox stays useful. That includes:
- Bulk deleting old or irrelevant messages by sender, date, size, or category
- Mass unsubscribing from newsletters and marketing emails you no longer read
- Organizing remaining messages into folders, labels, or archives
- Automating ongoing cleanup so new junk never piles up again
The problem is that doing this manually, one email at a time, is impractical when you have 10,000 or 50,000 messages. That is where dedicated email cleaning tools come in.
How Mailstrom Cleans Your Email
Mailstrom is an email cleanup tool built to handle inboxes at scale. Instead of making you deal with emails one by one, Mailstrom groups your messages intelligently and lets you act on hundreds or thousands at once.
Smart Grouping
Mailstrom analyzes your inbox and groups messages by sender, subject, time period, size, and other attributes. You can instantly see which senders are flooding your inbox, which subscriptions you have forgotten about, and where the bulk of your clutter is coming from. Then you clean it in a few clicks — not a few hours.
One-Click Unsubscribe
See every mailing list and newsletter you are subscribed to in one view. Unsubscribe from the ones you no longer want with a single click, without hunting through individual emails for tiny unsubscribe links.
Auto Clean
Set rules to automatically handle incoming messages that match your criteria. Move, archive, delete, or mark as read — Mailstrom keeps your inbox clean on an ongoing basis, not just as a one-time project. You set it once, and it works continuously in the background.
Bulk Actions
Move thousands of messages to trash, archive them, or label them in seconds. Mailstrom handles the heavy lifting that would take hours to do manually through your email provider's interface.
Privacy-First Email Cleaning
Here is what makes Mailstrom fundamentally different from most email tools: Mailstrom never reads the content of your emails.
Mailstrom works with metadata only — sender addresses, subject lines, dates, and sizes. It does not scan your email body text, does not analyze your conversations, and does not use your messages to train AI models or serve advertising. Your email content stays between you and your email provider.
This is not a marketing claim — it is an architectural decision. Mailstrom was designed from the ground up to deliver powerful inbox management without ever needing to access the actual content of your messages. For anyone who cares about email privacy (and you should), this matters.
Works With Every Major Email Provider
Mailstrom connects to the email accounts you already use:
- Gmail and Google Workspace
- Outlook and Microsoft 365
- Yahoo Mail
- iCloud Mail
- Any IMAP-compatible provider (Fastmail, ProtonMail via IMAP Bridge, Zoho, and more)
You do not need to switch email providers or change your workflow. Connect your account, clean up, and keep going with the tools you already use.

Frequently Asked Questions
Is Mailstrom safe to use with my email?
Yes. Mailstrom connects via OAuth (the same secure method used by apps like Slack and Zoom) and processes only metadata — never email content. Your credentials are never stored on Mailstrom's servers. You can revoke access at any time from your email provider's security settings.
How many emails can Mailstrom clean?
Mailstrom loads up to 5,000 messages at a time and can process your entire inbox in batches. Users regularly clean 10,000, 50,000, or even 100,000+ emails using the tool.
Does Mailstrom permanently delete emails?
Mailstrom moves messages to your email provider's trash folder, just like deleting manually. Most providers keep trashed messages for 30 days before permanent deletion, giving you time to recover anything you need.
Can I clean email on my phone?
Mailstrom is web-based and works in any modern browser, including mobile browsers. For iOS users, Chuck (also from 410 Labs) provides a native mobile email experience with similar batch-processing capabilities and on-device AI.
How is Mailstrom different from Clean Email?
The biggest difference is privacy. Mailstrom processes metadata only and never reads email content. Mailstrom also offers more flexible grouping options and Auto Clean automation with multiple action types (move, archive, delete, mark read).

What does Mailstrom cost?
Mailstrom starts at $9/month or $59.95/year, with a 14-day free trial. No credit card is required to start. See all plans at mailstrom.co.
