Questions
Should I use MailMop or DeclutrMail for finding the senders that fill your inbox?
Both rank Gmail senders by how much they send. MailMop analyzes in your browser and can be self-hosted. DeclutrMail scans on our servers without fetching full email contents, then lets you decide each sender with a preview and 30-day Undo.
Can DeclutrMail see my full emails?
No. We never fetch or store full email contents. DeclutrMail asks Google for one Gmail permission, gmail.modify, and uses it to list the email details shown on our security page and to make the changes you confirm.
How much does DeclutrMail cost?
Free is $0 and lets you clear 50 emails a month; Unsubscribe, Keep, Later, previews and Undo are unlimited. Plus is $90 a year with no monthly limit.

What Google will ask you to allow
Google’s screen asks for one Gmail permission, gmail.modify, and words it more broadly than DeclutrMail uses it: DeclutrMail moves and labels email and never sends email as you. We never fetch or store full email contents.
