Send personalised bulk emails to your opted-in contacts directly from Gmail — using data from Google Sheets or CSV files.
Add to Chrome — It's FreeMailMerge Pro is a Chrome browser extension that lets you compose a personalised email template — using merge tags like {{first_name}} or {{company}} — and send individual, personalised emails to each recipient in your list, all via your own Gmail account.
You load your recipient list from a Google Sheet or a CSV file. MailMerge Pro substitutes the merge tags in your subject and body for each row, then sends (or schedules) the emails through the Gmail API on your behalf. No third-party email service is required — emails come from your Gmail account and appear in your Sent folder.
MailMerge Pro is designed for sending to opted-in, consented recipients only — such as existing customers, newsletter subscribers, or event attendees who have explicitly requested to hear from you.
