Clean Email vs Mailstrom

Clean Email

• Clearing a backlog of thousands of old emails
• Unsubscribing from many mailing lists in one sitting
• Families or small groups sharing a 5 or 10 account plan

Mailstrom

• Clearing thousands of old messages out of a neglected inbox
• People who want to choose what goes themselves instead of relying on AI sorting
• Cleaning several mailboxes: Pro covers 20 email accounts

Clean Email

• A free account can clean 1,000 emails, plus 100 a week with reminders on. Screener, Auto Clean and the Unsubscriber need a paid plan.
• It is not an email client: it connects to your mailbox and works alongside the email app you already use.
• Prices here are US prices from the App Store listings and Clean Email's own pages. Its plans page shows local-currency prices that vary by region.
• The US App Store lists 5-account purchases at several prices without a billing period, so that plan's price is given as a range.

Mailstrom

• It runs in the browser only; the site lists no mobile or desktop apps.
• The free trial is a one-time snapshot of up to 5,000 messages, and only 25% of them can be deleted, archived or moved.
• It works over IMAP, so POP-only accounts and Exchange servers without IMAP enabled cannot be connected.
• Basic is capped at 1 email account and 10,000 emails, and the FAQ says folders other than the inbox cannot be organized yet.

Clean Email

Unsubscriber

Lists every subscription and newsletter in one place and unsubscribes for you. If a list ignores the request, its messages are moved to the trash automatically.

Bulk cleaning

Groups mail by sender, date or size so that thousands of messages can be deleted, archived, labelled or moved in a single action.

Smart Folders and Cleaning Suggestions

Predefined filters gather mail such as social notifications, rideshare receipts and online shopping, and suggestions point to messages people usually delete or archive.

Screener

Holds messages from senders who have never emailed you before, so you can allow or block each one before it reaches the inbox.

Auto Clean rules

Rules based on sender, domain, status or age automatically move, star, mark, delete or archive messages as they arrive or once they get old.

Privacy Monitor

Checks your email address against known data breaches on a regular basis and alerts you if it has been compromised.

Mailstrom

Bundles of related mail

Groups inbox messages by sender, subject, date and size so that tens, hundreds or thousands of them can be deleted, archived or moved to a folder in one action.

Unsubscribe

From the Mailing Lists tab, Unsubscribe sends a request email to the list owner. If the list gives no unsubscribe address, its web page opens in a new tab instead.

Block

Removes the selected messages and creates a rule that keeps future mail from the same sender, mailing list or subject out of the inbox. Available to subscribers.

Chill and Expire

Chill takes messages out of the inbox and returns them on a date you choose. Expire removes mail from a sender or mailing list after a set period. Both need a subscription.

Automatic move rules

A move can be saved as a rule, so future messages that match a sender or subject are filed into the chosen folder as they arrive. Subscribers' mail is loaded continuously.

Undo and task history

Actions are carried out by your email service and are not permanent: deleted mail goes to its trash, and an Undo feature reverses any command from the task list.
