Mergo Mail Merge: The 2025 Review - cover photo

Before cold outreach became the hot new thing, marketers used something called mail merge. This simple approach combined Google Sheets and Gmail to send out a large number of emails with some level of personalization. Then came mail merge tools such as Mergo that took things to the next level.

Once you grab Mergo from the Google Workspace Marketplace, you can launch full-blown email campaigns with nothing but a Gmail inbox.

Today, we’ll show you what Mergo does and whether you should consider some better options.

What is Mergo?

Mergo pricing

If you want to pay monthly, there are three plans. The plan for a Gmail address is $5.99 per month for up to 500 emails per day, and it includes the main features such as email tracking and analytics, and some AI features.

The Google Workspace plan is $7.99 per month and gives you up to 2,000 emails per day, and all the main features.

Lastly, you can purchase Mergo for your domain at $45 per month, and get 2,000 emails per day per user and all the features mentioned above. As for purchasing Mergo one time and forever, you can get it for Gmail at $50 per user and for a Google Workspace at $100 per user.

What Mergo users are saying

Limited usability compared to more established mail merge tools. It’s easy to get blacklisted if you’re not careful. The email limitations are not set in stone and it can be very unpredictable when you’ll hit them.

Some users voice their concerns that despite being able to reach many subscribers, there is a high likelihood of getting blacklisted:

  • “As it is connected directly with google workspace If you try to mail multiple people you’ll get blacklisted easily. It is better for small outreach like maximum 50 per day. Have certain analytics limitation as well. But consider this is a simple mail merge tool” Source.
  • “Sometimes, I find that the emails will directly go into spam. And this is not often this happens may be for 1-2 mails among 100 mails.”Source.

  • “What bothers me most about Mergo Merge is its unpredictable email sending limits. Even though I’m supposed to be able to send 500 emails per day, I often hit these limits early, causing emails to bounce or get blocked by Gmail. It’s frustrating and disrupts my plans for communicating with clients.When I encountered issues with hitting email sending limits prematurely, the support response was not as prompt or helpful as I had hoped. Clearer guidance and quicker resolutions would greatly improve the customer support experience.”Source.
