Top 9 YAMM Alternatives to Upgrade Your Email Marketing Strategy in 2025

Do you already have an email marketing strategy?

No doubt you’ve considered YAMM at some point. But YAMM isn’t the only option—and for many teams, it’s definitely not the best one.

That’s why we’re taking a closer look at the top 9 YAMM alternatives.

What Is YAMM and Why Look for an Alternative?

Key Features

Yet Another Mail Merge (YAMM) is a popular mail merge tool for Gmail and Google Sheets. It’s an add-on that integrates directly with Google Sheets, available on the Google Workspace Marketplace.

Main Features:

• Ability to insert dynamic variables.

• Open, click, and reply tracking directly inside Google Sheets.

Weak Points

While YAMM does offer some solid features, it also comes with weaknesses that can hold back your business goals.

Here are a few of them:

❌ Limited free plan: no scheduling feature, only “best effort support”.

❌ Emails are sent all at once.

❌ Requires read access to your Gmail inbox and Google Drive files.

❌ Ease of use is not unanimous (some users find it difficult).

❌ Team pricing model isn’t optimal: for 51 users, you’re required to pay for 100.

❌ The “Free” plan is capped at 20 recipients per day, even though Gmail’s sending quota is 1,500 recipients per day.

💡 I first drafted this article in 2024, and back then the “Free” plan was limited to 50 recipients per day. Today, it’s down to just 20.

Any questions ?

What is the Difference between Mailmeteor and YAMM?

Mailmeteor and YAMM (Yet Another Mail Merge) are both Google Sheets add-ons.

The main difference lies in their philosophy and features:

• YAMM is effective for basic mail merge.

• Mailmeteor focuses on privacy (no direct access to your Gmail inbox).

Is YAMM Trustworthy?

YAMM is generally considered reliable, but like with any third-party tool, there are important nuances. In particular, YAMM requires read access to your Gmail inbox and Google Drive files.

This is not an issue with Mail Merge for Gmail, which never accesses your Gmail inbox.

Is There A Better Alternative To Mail Merge?

It depends on your needs.

• For simple, one-off personalized emails, a mail merge add-on like Mail Merge for Gmail is often the easiest option.

• For advanced outreach (follow-ups, deliverability tools, multichannel), dedicated sales engagement platforms like Lemlist, Mailshake, or Woodpecker go beyond traditional mail merge.
