Master Gmail Mail Merge in 2025

Top Add-Ons, Step-by-Step Setup, and Deliverability Hacks

Why “Mail Merge Gmail Add-On” Is a Hot Keyword in 2025 🚀

Search phrases like “mail merge Gmail add-on,” “Gmail mail merge tool,” “Google Sheets mail merge,” and “Gmail mass email” rack up thousands of monthly queries because they solve a universal pain point: sending personalized bulk email (a.k.a. bulk email with Gmail) from an inbox people already trust.

Add-ons do the heavy lifting, so you don’t need separate email-marketing software or code. Google introduced a basic Mail Merge (Multi-send) mode in late 2023, but it’s limited to certain Workspace tiers and supports just four default tags (@firstname, @lastname, @fullname, @email).

If you want custom fields, tracking, or automated follow-ups, you still need a dedicated Gmail mail merge add-on.

What Exactly Is a “Mail Merge for Gmail”?

Mail merge combines a single email template with rows in a Google Sheet. The add-on replaces placeholders like {{FirstName}} with each recipient’s real data, then sends those messages as individual emails from your Gmail account.

Benefits:

  • Time-saver: One draft → 10 or 10,000 personalized sends.
  • Higher engagement: Using real names & details beats a “Dear Customer” blast.
  • Better deliverability: Because the emails leave your own Gmail account, they often land in the Primary tab, not Promotions.
