EmailSlim vs Smart Delete for Gmail

EmailSlim is a web service for finding storage-heavy messages in Gmail and Microsoft email accounts and cleaning them up. It analyzes metadata rather than email body content, ranking senders and domains by the total storage their messages use. Users can inspect grouped senders and approve bulk deletions; messages first move to Trash or Deleted Items. One-click unsubscribe uses standard List-Unsubscribe headers when available, though it may not work for every sender. Supported accounts include Gmail, Outlook, Hotmail, Live.com, MSN, and Microsoft 365. Connections use Google OAuth or Microsoft OAuth, and access can be revoked in account settings. EmailSlim says operations require explicit user consent and initiation. It describes encryption in transit and at rest, access controls, and regular security audits. The free scan costs nothing and covers the first 500 emails without a credit card or subscription. Paid pricing is from $2.50/mo. One-time, annual, and monthly automation plans use mailbox tiers up to 150k emails, with exact amounts shown after sign-in. Monthly automation is described as daily inbox cleanup.

Smart Delete for Gmail is an extension and web add-on that helps Gmail users remove messages in bulk through pattern-based recommendations and rules. It detects recurring email patterns, uses behavior to create deletion rules, and suggests cleanup opportunities among frequent senders. Users can target senders or subject keywords, queue multiple deletions, and preview matches before acting. Starred and important emails are excluded automatically; deleted messages move to Gmail Trash and remain recoverable for 30 days. The add-on appears in Gmail’s sidebar and is available through Google Workspace Marketplace. Its stated permissions cover the open email’s sender and subject, mailbox searches for defined rules, and moving matching threads to Trash; it says email bodies and attachments are not accessed. Plans include Free at free, Light User at $1, paid once, Regular User at $2, paid once, and Power User at $10, paid once.
