Gmail Duplicate Sender

Gmail Duplicate Sender adds a blue "Duplicate" button when you open emails in Gmail. HOW IT WORKS • Open any email in Gmail (Sent, Inbox, etc.) • Click "Duplicate" next to Forward on the message you want to copy • A new compose draft opens with that message's subject and HTML body • Enter your recipient and send — it's a new email, not a forward or reply THREAD SUPPORT • In email threads, each message gets its own Duplicate button • Duplicate your original sent email without copying someone's reply • Duplicate a reply without copying the whole thread history FEATURES • Works inside Gmail — no OAuth or Gmail API setup required • Preserves original email HTML formatting • Strips Re: and Fwd: from the subject automatically • Detects attachments and reminds you to re-attach them manually • Matches Gmail light and dark themes PRIVACY • All processing happens locally in your browser • No data is collected, stored, or sent to any server • Only runs on mail.google.com PERMISSIONS • mail.google.com — required to inject the Duplicate button and read the open email's subject/body to pre-fill a new compose draft
