Web App
The Mail Merge web app lives at merge.email/app. It is the companion to the Google Sheets add-on: everything you send from the add-on shows up here, and the templates you save here are available back in the add-on. Sign in with the same Google account you use in Google Sheets.

What you can do here
Section titled “What you can do here”The web app is organized around four sections in the left sidebar, plus your billing pages:
- Campaigns — every campaign you have sent, with live progress and status.
- Templates — your saved email templates, editable in a rich-text editor and shared with the add-on.
- Contacts — everyone your campaigns have emailed, with the data used to fill your templates.
- Settings — deliverability controls (how fast your campaigns send).
- Pricing & subscription — compare plans and upgrade.
