GMass Review: Still Great for Cold Email?

If you're looking for an email tool to send bulk emails straight from Gmail, you've probably heard of GMass.
It's been around for a while and has built a solid reputation for being simple and effective. But is it still a good option in 2025?
Let's look into it and break it down.
What is GMass?

GMass is a Chrome extension that integrates directly with Gmail. It allows you to send bulk emails, automate follow-ups, and manage email campaigns without leaving your inbox.
Unlike other cold email tools, GMass doesn't have its own interface. Everything happens inside Gmail.
So, if you love working from your inbox, this is great but if you're looking for a full-fledged outbound sales tool, you might need something more robust.
GMass Features
Let’s run through what features GMass offers and break them down.
Email Campaigns Inside Gmail

GMass lets you create and send email campaigns without switching to another tool. If you're already comfortable with Gmail, this keeps things simple.
Automated Follow-Ups

Follow-ups are key to getting replies. GMass lets you set up automatic follow-ups if recipients don't respond. You can schedule multiple follow-ups and customize them easily.
Google Sheets Integration

GMass can pull recipient lists directly from Google Sheets. If you have an existing list of contacts, this makes importing them a breeze.
Mail Merge with Personalization

You can personalize emails using placeholders (like first name, company name, etc.) pulled from Google Sheets.
Open and Click Tracking

Want to know who's engaging with your emails? GMass tracks opens and clicks, giving you insights into your campaign’s performance.
What Features is GMass Missing?
Before jumping in, it's important to know GMass isn't a full sales automation tool. Here’s what it lacks:
- No Email Finder: GMass won’t find emails for you. You need your own list.
- No AI Personalization: Some newer tools auto-generate personalized emails. GMass doesn’t.
- No LinkedIn Integration: You can’t reach prospects across multiple channels.
- No Advanced Sending Algorithms: Emails are sent in bulk, not spread out to mimic human behavior.
If you're in need of some of these features, you might need a different tool.
Who is GMass For?
GMass has a simple to use interface and isn’t for everyone so let’s break down who should use GMass.
GMass is great for:
- Individuals or small teams who want a simple way to send bulk emails.
- Event organizers sending invitations.
- Non-profits reaching out to supporters.
- Job seekers or freelancers looking to contact multiple prospects at once.
If you're a sales professional or a growth marketer looking for an advanced automation tool, GMass might feel limiting.
How Does GMass Work?
Using GMass is straightforward:
- Install the GMass Chrome extension.
- Open Gmail and compose a new email.
- Select a list of recipients (Google Sheets integration makes this easy).
- Set up automated follow-ups if needed.
- Click the GMass button instead of the regular Send button.
Once sent, GMass takes care of tracking opens, clicks, and replies.
How Much does GMass Cost?
GMass is affordable compared to other tools. Here’s a quick breakdown:
- Free Plan: Up to 50 emails per day.
- Standard Plan: $19.95/month (basic email campaigns).
- Premium Plan: $29.95/month (includes follow-ups and reporting).
- Team Plan: $49.95/month per user (advanced features for teams).
All in all, GMass is super affordable for what you get.
Final Thoughts
GMass is simple, affordable, and does what it promises. If you just need a basic bulk email tool, GMass is an awesome choice.
But if you're in sales and need LinkedIn automation, email discovery, and more, the best GMass Alternatives are going to be Lemlist and LeadLoft. Both of which offer email finders, phone finders, LinkedIn automation, and advanced sales tools.
Regardless, be sure to do your research, consider your needs, and select the tool that is best for your team.
