Bulk Delete Emails — Fast & Safe

Need to bulk delete emails in Gmail or Outlook? EmailSlim shows you which senders are using the most storage — so you can delete intelligently, not manually.

Your email content stays private — we only analyze metadata

EmailSlim never deletes emails. All deletions happen in your inbox when you approve them.

Example: 6,400 emails × 180KB = 1.1GB reclaimed.
