GoodByEmail vs MailMop

GoodByEmail analyzes an exported inbox to show which senders use storage and help users decide what to clean up. Users import an MBOX or Outlook PST file, then filter or sort senders by storage, email count or last received date. The app can identify mailing-list senders and supports one-click unsubscribing. It does not scan or delete messages automatically: users export their inbox and remove selected emails in their email client. The maker says mailbox processing happens locally, without uploading or storing email content, metadata or mailbox statistics on its servers. Scanning can work offline after an online login unlocks the app. The free version shows unordered results for everyone who has emailed the user; actionable cleanup insights require a license. Paid options include Lite at $9.99 a month, Plus at $14.99 a month and Pro at $19.99 a month. A Perpetual license costs $199 as a one-time purchase. The platform list includes macOS, Windows and self-hosted.

MailMop is a Gmail inbox-cleaning tool for identifying clutter and managing messages in bulk. It groups clutter by sender and shows message counts, then provides actions such as deleting, blocking senders, unsubscribing, marking messages read, applying labels, and creating filters. Gmail headers are analyzed through the Gmail API; when message content is needed to locate unsubscribe links, processing occurs in the browser rather than on MailMop servers. The service says it handles inboxes up to 500,000 emails, while its FAQ states there is no processing limit. MailMop works with one inbox at a time, but one Pro subscription covers all of a user’s inboxes. Basic is free and includes unlimited analysis, sender statistics, unsubscribe, export, and Gmail links. Pro costs $1.89 a year, billed annually at $22.68/year, adding one-click bulk actions, bulk delete, advanced filtering and labels, and sender blocking. It is available on the web or can be self-hosted for free.
