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

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.
