About GCampaign — Mail Merge for Gmail

GCampaign turns Gmail into a powerful mail-merge and mass-email tool. Import recipients from a Google Sheet, personalize each message with merge fields, and send personalized campaigns to hundreds of contacts — straight from your Gmail account. ★ MAIL MERGE MADE SIMPLE Connect any Google Sheet whose first row is a header. GCampaign detects your columns (name, email) and turns them into merge tags you can drop into your subject and body. ★ PERSONALIZED, ONE-TO-ONE EMAILS Every recipient gets their own individual message — no BCC, no "undisclosed recipients". Just real, personal emails sent from your Gmail address. ★ SCHEDULE & THROTTLE Schedule campaigns to go out later, and cap sends per hour to respect Gmail's limits and protect your sender reputation. ★ BUILT INTO GMAIL A clean side panel and compose bar appear right inside Gmail. Draft, review and launch campaigns without leaving your inbox. ★ PRIVATE BY DESIGN Your contacts stay in your browser. Emails are sent directly through your own Gmail account via Google's official API. We never see, store, or sell your data. GCampaign is perfect for sales outreach, recruiting, newsletters, event invitations, invoices, and any time you need to send the same message to many people — personalized.
