Yet Another Mail Merge (YAMM) Review — Honest Pros, Cons & Pricing (2026)

Category: Google Sheets mail merge for Gmail

Website: yamm.com

Also known as: YetAnotherMailMerge(YAMM), yetanothermailmerge(yamm), yet another mail merge (yamm).

Overview

YAMM is one of the original Google Sheets mail merge tools — it has been around since 2014 and has a massive user base (over 5 million installs). Like Mailmeteor, it lets you send personalized emails from Gmail using Google Sheets as the data source. Tracking includes opens, clicks, bounces, and unsubscribes. YAMM supports HTML emails with images, which makes it useful for marketing-style cold outreach (though plain text usually performs better for cold email). The main advantage over Mailmeteor is more mature features and a longer track record.
