Sender Copilot

Personalized outreach, sent one at a time from your Gmail

Sender Copilot helps non-profit volunteers send personalized, individually reviewed emails directly from their own Gmail account. Each message is personally composed, previewed, and explicitly sent by the user — one recipient at a time — replacing a fully manual process while keeping a human in control of every send.

1 Add recipients — paste email addresses, upload a CSV, or type them in
2 Compose or personalize your message — preview exactly how it will read for each person
3 Review the personalized preview, then explicitly send — one person at a time, every time

Gmail send-only access · no inbox reading · every send is a direct user action
