What is MailG?
Mail merge for Gmail from Google Sheets — templates, campaigns, tracking, and billing in one add-on.
MailG turns a Google Sheet into a mail-merge campaign. Each row is a recipient; column headers become merge tags (double curly braces around the header name) in the email body.
What you can do
- Create cloud-backed templates (Template Name, Email Subject, rich body)
- Personalize the body with merge tags from sheet headers
- Preview rows and Send me a test email
- Map CC / BCC, Sender name, Reply to address
- Schedule send or send immediately
- Track emails with open status chips in the sheet
- Control Send pacing on paid plans
- Remove branding on paid plans
- Watch Daily quota (and optionally claim a free review bonus)
