What is YAMM?

YAMM (Yet Another Mail Merge) is a mail merge tool for Gmail and Google Sheets. It allows users to send personalized bulk emails directly from their Gmail accounts by pulling recipient data from a Google Sheets spreadsheet.

With YAMM, you can:

• Send mass personalized emails
• Schedule emails to be sent at a later time.
• Track email performance

This Google Workspace add-on integrates with Gmail, making it a popular choice for sales teams, recruiters, educators, and small businesses looking to run outreach campaigns without using a dedicated email marketing platform.

How does YAMM work?

Yet Another Mail Merge (YAMM) works by merging data from a Google Sheets spreadsheet with a pre-written email template in Gmail, allowing users to send customized messages at scale.

Here’s how to use YAMM:

Step 1: Install the YAMM add-on

To start using YAMM, you need to install the Yet Another Mail Merge add-on from the Google Workspace Marketplace and grant it the necessary permissions.

Step 2: Prepare your Google Sheets contact list

YAMM uses Google Sheets as a contact database. Each row represents a recipient, and each column contains personalized details like:

• Email address (mandatory)
• First name, last name
• Company name
• Custom variables (event date, discount codes, job title…)

Step 3: Create your email template in Gmail

Write your email inside Gmail and use merge tags (like {{First Name}}) to dynamically customize each message.

Step 4: Send personalized emails

Go back to Google Sheets, open YAMM, and send your campaign immediately, or schedule emails for later.

Step 5: Track Email Opens & Clicks

YAMM includes basic email tracking, allowing users to monitor email opens, clicks, unsubscribes, and bounces.

Pros & Cons of using YAMM

With 10M+ downloads, YAMM is a (very) popular mail merge. But this tool isn’t perfect. In this section, we’ll break down the pros and cons to help you determine if Yet Another Mail Merge is the right tool for your email outreach.

Pros of YAMM

• Seamless Gmail integration – YAMM works directly within Google Sheets and Gmail, making it easy to send personalized bulk emails without switching platforms.
• Affordable pricing – Compared to many email marketing platforms, YAMM offers budget-friendly plans starting at just $36 per year.
• Email tracking – Users can monitor email opens, clicks, bounces, and unsubscribes to measure campaign performance.
• Easy to use – YAMM is simple to set up, requiring no technical expertise to create and send mail merge campaigns.

Cons of YAMM

• Limited daily sending limits – Even on the highest plan, YAMM only allows 1,500 emails per day, which may not be enough for larger outreach campaigns.
• No automation features – Unlike more advanced outreach tools, YAMM does not support email sequences or drip campaigns.
• No built-in email verification – YAMM lacks email verification, which means users risk higher bounce rates and deliverability issues.
• Lack of CRM and API integration – Unlike some competitors, YAMM does not integrate with CRMs or offer an API for advanced automation.
• No Outlook support – YAMM is designed exclusively for Gmail users and does not work with Outlook or other email providers.

Verdict: Is YAMM Worth It?

If you need a simple and affordable mail merge tool for Gmail, YAMM is a solid choice. Especially for educators, small businesses, and nonprofits looking to send less than 1,500 emails per day.

However, if you need higher sending limits, automated follow-ups, or better deliverability features, you may want to consider an alternative like Mailmeteor, which offers more advanced capabilities.
