YAMM review
A Google Workspace mail-merge tool with scheduling, follow-ups, and detailed engagement tracking.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
YAMM is an email campaign and mail-merge application for Gmail and Google Sheets. It is designed for individuals, small businesses, teams, marketers, sales users, educators, and organizations that need personalized bulk email within Google Workspace. Users can create scheduled mail merges, personalize subject lines and content, add links, images, and attachments, and send through Gmail. The service requires a Google account and uses a Google Sheets add-on together with the Gmail API.
Its feature set extends beyond one-time scheduling. YAMM supports follow-up campaigns, same-thread follow-ups, custom HTML email templates, one-click surveys, and Google Form email notifications. Engagement tracking covers opens, clicks, responses, bounces, and unsubscribes, while sending options include CC/BCC and email aliases. Integrations with Gmail, Google Sheets, Google Contacts, Salesforce, HubSpot, Copper, and Google Forms make it a practical fit for workflows that already organize contacts or campaign data in those services. Buyers seeking a focused Google Workspace workflow should find the combination of scheduling, personalization, and follow-up automation relevant; teams centered on another email platform should look elsewhere.
The published plan structure starts with Free, which includes tracking, scheduling, no branded footer, and best-effort support. Pro plans are offered for Gmail accounts and Google Workspace accounts, adding priority support while retaining the listed tracking, scheduling, and footer features. Team includes Google Workspace team seats and priority support, while Unlimited is a custom plan for larger organizations. This gives solo senders and smaller teams a clear entry point, with higher tiers aimed at support needs and organizational administration. YAMM is a strong choice for scheduled, personalized campaigns in Gmail and Sheets, but less suitable for organizations that need a standalone, multi-platform email system.
