Full disclosure up front: we make Sieve, so judge accordingly. Everything below about Leave Me Alone sticks to its own public positioning.
What is Leave Me Alone?
Leave Me Alone made its name on one job. It calls itself a privacy-first unsubscribe tool: it shows you the subscription emails in your inbox and unsubscribes you from unwanted newsletters and mailing lists in one click.
Its feature pages have since widened the job: Inbox Shield screens mail from first-time senders, and a Spam Blocker is aimed at filtering spam and cold email automatically. Its pricing page rounds out the toolkit with Rollups for bundling recurring mail, Shielded Emails, priority senders, and a do-not-disturb mode.
What Leave Me Alone does well
- The core loop is easy to evaluate (see your subscriptions, leave the ones you don't want) and cheap to try: 10 unsubscribes free with no credit card, per its pricing page, or the whole toolkit for a $19 one-off seven-day pass.
- It addresses cold email head-on: per its own pages, Inbox Shield screens first-time senders, and the Spam Blocker targets spam and cold email automatically.
- Its plans scale from 4 accounts (Casual Emailer) to unlimited (Inbox Zero Hero), per its pricing page, with a 14-day money-back guarantee on paid plans.
Leave Me Alone pricing
As of July 2026, leavemealone.com's pricing page lists a free start (unsubscribe from 10 emails, no credit card), a Seven Day Pass at $19 one-off covering two accounts, Casual Emailer at $9 a month or $54 a year billed yearly (four accounts, a 40% saving in its own framing), and Inbox Zero Hero at $16 a month or $64 a year (unlimited accounts, 60% off yearly), with a 14-day money-back guarantee on paid plans. The pass is the distinctive one: a one-off purge with no subscription. Sieve, for comparison, is $10 a month for Basic or $20 for Pro, which adds a second inbox; both are 15% off yearly with a 7-day free trial.
Where Sieve fits differently
Sieve ships with its judgment built in and learns yours as you go. Every incoming message is classified server-side within seconds. Cold outreach goes under a Solicitor label, phishing under Malicious, and both are archived out of your inbox rather than deleted. When it gets one wrong, drag the message back; the correction is recorded automatically and future classifications improve. Reply to someone and Sieve treats them as a trusted sender from then on. And you can steer it in plain English: "I'm not interested in recruiter pitches."
By its own account, Leave Me Alone has grown well beyond unsubscribing, screening first-time senders and blocking cold email. The difference with Sieve is where the work happens. Sieve operates inside Gmail or Outlook, so flagged mail is filed as Solicitor or Malicious in the mailbox you already have open, and a wrong call gets fixed where it happened. Phishing links are screened through Google Web Risk. And for the list mail Leave Me Alone was built around, Sieve has an answer of its own. Smart Unsubscribe scans your last 90 days of message headers for recurring lists, sends a real one-click unsubscribe request (RFC 8058) where the sender supports it, and blocks and files the list as a backstop, so a sender that ignores the request stays out of your inbox regardless.
Mail from people you already know (your domain, trusted senders, anyone in a thread with you) is cleared by deterministic rules before any AI runs, so its contents are never read by the model. Sieve stores no message bodies (mostly metadata, plus the subject line of flagged mail, encrypted and deleted after 30 days), and nothing is used to train models. Google's security review is complete, and SOC 2 Type II is in progress. Read the Privacy Policy.

When Leave Me Alone is the better choice
Pick Leave Me Alone over Sieve if:
- Your unwanted mail is almost entirely newsletters you once signed up for, and a dedicated unsubscribe pass is all you need: the $19 seven-day pass exists for exactly that.
- You're not on Gmail or Outlook. Sieve supports those two providers through their direct APIs. It does not support Yahoo or custom IMAP.
- You're covering many mailboxes: its Inbox Zero Hero plan covers unlimited email accounts for $16 a month, per its pricing page; Sieve covers at most two inboxes (the second comes with the $20 Pro plan).
