RightSend Mail Merge — Send the Right Document to the Right Person

Gmail mail merge with a unique attachment per recipient and scheduled sending — we never see what you send.

RightSend Mail Merge sends the right email — and the right document — to every recipient, automatically. RightSend Mail Merge is built for the one job every other Gmail mail-merge tool treats as an afterthought: sending a different, correctly-named file to every person on your list. Certificates, invoices, offer letters, payslips, event tickets — pick the files, and RightSend matches each one to the right row and renames it for the recipient, automatically, then sends it as part of a genuinely personalized email. WHAT IS MAIL MERGE? Write one email once — subject and body — and let RightSend fill in every recipient's own name, details, and attachment from your spreadsheet. No copy-pasting, no manual renaming, no "which invoice goes to which person" spreadsheet juggling. WHY RIGHTSEND? 📎 A different attachment for every recipient (Pro) Select a batch of files — RightSend matches each one to the right row by filename and can rename it before sending (e.g. Invoice_{{Last name}}.pdf). No other mail-merge extension makes this the headline feature. 🔒 Genuinely private, by architecture RightSend runs 100% client-side. Your recipient list, attachments, and email content are never uploaded to any server of ours — because we don't have one. We literally cannot see the certificates, payslips, or invoices you send. ✅ Works on a free @gmail.com account No Google Workspace subscription required for any core feature. ✉️ Personalized subjects, CC/BCC, per-row CC — free Merge fields work in the subject line too, not just the body. 📊 Bring your own data — Google Sheets or local Excel/CSV Connect a Google Sheet, or import a local .xlsx/.xls/.csv file with no Google account needed for that path. ⏰ Schedule sends for later (Pro) Queue a batch to go out at a specific time, even if you close the popup — powered by Chrome's own alarm scheduler. 🛡️ Built-in send pacing to protect your account Free Gmail accounts can get flagged for sending too many near-identical emails too fast. RightSend paces every batch conservatively by default — for everyone, free or paid. 📋 Row-level errors you can actually act on "Row 14 is missing an email address" instead of a cryptic failure halfway through a send. 📥 Export a full send report Download an Excel log of every send — recipient, merged subject, attachment filename, status, and failure reason — after any batch completes.
