# What is MailG?

MailG is a Google Sheets add-on for mail merge with Gmail. Each spreadsheet row is a recipient; column headers become merge tags in the email body. Messages are sent through the user's own Gmail account (not a MailG ESP).

## Short definition

Mail merge for Gmail from Google Sheets — personalize mass emails, schedule sends, and track opens from your spreadsheet.

## Who it is for

- Founders and operators running outbound from Sheets
- Sales and CS teams who already live in Google Workspace
- Agencies sending client campaigns from Gmail
- Anyone who wants mail merge without leaving Sheets / Gmail

## What you can do

- Create cloud-backed templates (name, subject, rich body)
- Personalize the body with merge tags from sheet headers
- Preview rows and send a test email to yourself
- Map CC / BCC, sender name, and reply-to
- Schedule send or send immediately
- Track opens with status chips in the sheet
- Control send pacing and remove branding on paid plans

## What MailG is not

- Not a bulk email service provider that sends from MailG IPs
- Not a full CRM or sequence product
- Not an SMTP API for third-party apps
