Imagine you have a Google Sheet with columns for First Name, Company, and Pain Point. You can create a single email template that pulls data from these columns to send highly personalized emails to hundreds of prospects at once.

Importance in Cold Email:

Generic emails are the white noise of the internet—easily ignored. Mail Merge transforms your outreach by personalizing each email down to specific details like the prospect’s name, company, and even their specific needs or challenges. This not only boosts engagement but also makes your emails feel less like spam and more like a tailored message. In an era where personalization is key to standing out, Mail Merge with Google Sheets is your secret weapon for making every prospect feel like they’re receiving a one-on-one message.

Bypass Gmail’s Limitations

GMass employs an advanced distribution system that allows you to send a campaign to over 500 people (or 2,000 for Google Workspace) without violating Gmail’s sending limits.

Real-life example:

You’ve got a hot product update and a mailing list of 3,000 eager subscribers. Instead of slicing and dicing your list to fit Gmail’s restrictions, GMass takes care of it by automatically spreading the emails across days or employing an SMTP server.

Importance in Cold Email:

Email campaigns often involve large volumes of messages, and hitting Gmail’s sending limits can be a bottleneck. This feature is like having a VIP pass at a crowded club, allowing you to bypass the line and get straight to business.

Behavior-Based Campaigns

What it is:

GMass offers a range of behavioral segments for your prior campaigns, including those that were sent, opened, didn’t open, clicked, didn’t click, etc.

Real-life example:

Let’s say you sent an initial email to 1,000 prospects. 200 opened it but didn’t click the CTA. With Behavior-Based Campaigns, you can specifically target this segment with a follow-up email that aims to convert them.

Automatic Reply Management

What it is:

This feature automatically organizes your responses, separating genuine replies from auto-responses and categorizing emails based on their positive or negative tone. Additionally, GMass offers a specialized tool called The Reply Project to help you efficiently manage and respond to these replies.

Real-life example:

You’ve just sent out a campaign and responses start trickling in. Normally, you’d sift through these manually to sort the real prospects from the noise.

It’s the simplest way to conduct market research without being intrusive, enhancing your relationship with your prospects by showing that you value their input.

Automatic Unsubscribe Management

What it is:

GMass offers an automatic unsubscribe management feature that takes care of adding an “unsubscribe” link to your emails and handling unsubscribes effectively.

Real-life example:

Let’s say you’ve launched a campaign to a list of 1,000 recipients. Among them, 20 decide to unsubscribe. Instead of manually removing these contacts from your list, GMass’s Automatic Unsubscribe Management takes care of it, ensuring that these contacts are not included in future campaigns.
