In today’s fast-changing online world, where it’s really important to connect with people in a personal way, using tools to send cold emails has become super important. 

These tools streamline and optimize the outreach process, enabling businesses like retailers and tech companies to connect efficiently with potential clients and partners.  

In this comprehensive guide, I’ll explain what exactly cold email automation is and why it’s so useful in your outreach efforts. I’ll talk about the key features, pros and cons, and pricing plans for the 22 most popular cold email tools I’ve tested and reviewed. As a final touch, I will provide insights on how to pick the best tool for sending cold emails so that you can boost your B2B outreach efforts with the right choice for your business! 

So, What is Cold Email Automation?

Cold email automation refers to the process of using specialized software to streamline and systematize the sending of unsolicited emails to a large number of recipients without prior contact. 

This approach aims to initiate new business connections, outreach, or marketing campaigns by automatically crafting and dispatching large numbers of emails. 

You might think ‘”Could I be mistaken for spam by sending out sizable emails to recipients?”. Well, cold emails are not necessarily recognised as spam if you do it correctly. 

Spamming happens when companies or individuals send irrelevant and unwanted emails to many people. In cold emailing, the key to preventing being seen as spam is to aim at the right audience interested in what you offer and provide valuable information about your offer in the emails you send. So it’s more like an ad where people can also choose not to receive it if they don’t want to. 

It’s crucial to strike a balance between automation and personalized engagement to prevent messages from appearing overly generic or spammy.

The Value of Cold Email Automation: Why Invest in Such Tools?

Cold email automation is a valuable strategy for expanding B2B outreach due to its ability to efficiently reach a wide array of potential business partners or clients. 

By automating the email-sending process, businesses can effectively scale their outreach efforts, targeting a larger pool of prospects that might be interested in their products or services. This method facilitates the initial contact and introduction, enabling businesses to initiate conversations and establish connections with a broader audience.

Investing in a cold email automation tool offers several advantages for businesses aiming to enhance their outreach efforts. 

Firstly, such tools save valuable time and resources by automating the repetitive tasks associated with sending individualized emails to many recipients. 

Secondly, they enable the personalization of messages at scale, ensuring each recipient feels valued and engaged. 

Additionally, these tools often provide analytics and tracking features, allowing businesses to monitor the effectiveness of their campaigns and make data-driven improvements. 

Ultimately, a cold email automation tool can empower businesses to navigate the intricacies of B2B outreach more efficiently and strategically.

How to Choose the Best Cold Email Automation Tool? 

Choosing the best cold email automation tool requires careful consideration.

While all the factors listed below are important considerations when choosing a cold email automation tool, some of them can be more important than others. 

Here are 15 considerations categorized in terms of importance to help you make an informed decision. Remember that the significance of each factor may vary based on your specific needs, goals, and priorities. 

Very Important

  • Define Your Requirements

Understanding your specific needs is crucial to ensure the tool aligns with your goals.

  • Email Personalization

Personalization is crucial for effective cold emailing. Ensure the tool allows you to personalize emails with recipient names, company details, and other relevant information.

  • Email Templates

Check if the tool provides a variety of customizable email templates. These templates can save you time and help you craft professional-looking emails.

  • Automation and Sequences

Look for the ability to create and automate follow-up sequences. Cold emails often require multiple touchpoints, and automation helps you manage these sequences efficiently.

  • Email Deliverability

A good tool should have measures in place to maintain high email deliverability rates and avoid being flagged as spam.


  • Tracking and Analytics

Comprehensive tracking and analytics are essential to measure the success of your campaigns. Look for tools that offer insights into open rates, click-through rates, response rates, and more.

  • Integration with Existing Tools

If you use other tools like CRM, marketing automation platforms, or customer support software, ensure that the cold email automation tool can seamlessly integrate with them.

  • Ease of Use

Look for a tool that is user-friendly and intuitive. Complex tools might require extensive training, whereas simpler tools can help you get started quickly.

  •  Pricing

Compare the pricing plans of different tools. Some offer tiered plans based on the number of contacts or emails, while others might have a flat fee. Consider your budget and the value provided by each plan.

Somewhat Important

  • Customization and Branding

The ability to customize emails to match your brand’s style and voice can contribute to a more professional appearance. While important, this factor might be less critical than others, depending on your branding needs.

  •  Customer Support

Responsive and helpful customer support can be a lifesaver when you encounter technical issues or have questions about using the tool effectively. Yet, it might not be a deal-breaker if other factors align well.

  • User Reviews and Reputation

Look for reviews and testimonials from other users to get an idea of how well the tool performs in real-world scenarios. Consider both positive and negative feedback. User reviews are important, but it’s not the only factor to consider.

Less Important

  • Trial Period

Whenever possible, choose a tool that offers a trial period. This gives you the chance to explore the tool’s features firsthand and evaluate whether it suits your needs. While useful, some users might feel confident enough to make a decision without a trial.

Dependent on Circumstances

  • Security and Compliance

Ensure that the tool adheres to email marketing best practices and data protection regulations, especially if you’ll be dealing with sensitive customer data. The importance of this factor depends on the nature of your business and the data you handle.

  • Scalability

Consider whether the tool can accommodate your growth. As your email list and outreach efforts expand, you’ll want a tool that can scale with your needs. Yet, if you’re just starting, scalability might be less important initially.

Ultimately, the best approach is to prioritize the factors that align with your immediate needs and long-term goals. If you find a tool that excels in the areas most critical to your success, it might be the right choice, even if it doesn’t excel in every single factor. Consider your unique situation, and focus on the factors that will have the most significant impact on your cold email campaigns.

Key Features

Chrome Extension for Gmail

Gmail users will appreciate Gmass’s Chrome extension, which allows you to send mail merges and cold email campaigns directly from your Gmail account. This convenient integration simplifies email marketing within the familiar Gmail interface.

Break Gmail’s Limits

One of the most significant challenges in email marketing is dealing with Gmail’s sending limits. Standard Gmail accounts are limited to sending up to 500 emails per day, while Google Workspace accounts can send up to 2,000 emails per day. Gmass tackles this issue head-on through automated distributed scheduling where it intelligently divides large campaigns over multiple days, ensuring you stay within your send limits. Alternatively, Gmass offers the option to use a third-party SendGrid SMTP server for mass emails in a single day. Additionally, you can opt to use your SMTP server for sending mass emails.

With this feature, you can create personalized mail merges using every column in your Google Sheet. What’s more, Gmass enables you to automatically send emails when new rows are added to your Google Sheet and offers a quick filtering feature for sending selected rows.

What’s impressive is the ability to schedule follow-ups, even skipping weekends, ensuring your emails reach your recipients at the optimal times. With options to edit or cancel follow-ups and send them in the same email thread, Gmass offers the flexibility you need to maximize engagement.

Segmented Campaigns

Personalization is key in effective cold email marketing, and Gmass takes it a step further with segmented campaigns. You can send new campaigns to segments of a previous campaign based on 12 different subscriber engagement criteria. This feature ensures that your messages are highly targeted and relevant, increasing the chances of conversion.

Email Polling

Engagement and feedback are vital for refining your email marketing strategy. Gmass allows you to add one-question surveys to your campaigns, providing valuable insights into recipient preferences and opinions. This data-driven approach can help you tailor future campaigns for better results.

Email List Builder

Building targeted email lists is fundamental to successful cold email marketing. Gmass simplifies this process with its email list builder. You can create focused lists by searching within your Gmail account, ensuring that you’re reaching the right audience for your campaigns.

Sending emails to invalid addresses can harm your sender reputation and deliverability. Gmass mitigates this risk by offering email verification. You can test every address before sending an email, ensuring that your messages reach active and valid recipients.

A/B Testing

Optimizing your email content is an ongoing process, and A/B testing is a powerful tool for it. Gmass enables you to test variations in your campaigns to determine what resonates best with your audience. This data-driven approach can significantly improve your email marketing success.

Personalization at Scale

Personalization is more than just using a recipient’s name. Gmass empowers you to personalize your emails at scale through mail merge and conditional logic. Tailor your messages to each recipient’s specific needs and preferences, increasing engagement and conversion rates.

Deliverability Tools

Ensuring that your emails land in the recipient’s inbox and not the spam folder is vital for email marketing success. Gmass offers a suite of deliverability tools, including the use of your tracking domain, a spam solver tool to optimize campaigns, and an Email Deliverability Wizard that provides data-driven answers to your deliverability questions.

Measuring the performance of your email campaigns is essential for refinement and improvement. Gmass provides comprehensive campaign analytics, offering nine different stats, including total recipients, unique opens, clicks, replies, unsubscribes, bounces, and more. These insights help you gauge the effectiveness of your campaigns and make informed decisions.

Automatic Reply Management

Managing responses to your email campaigns can be overwhelming. Gmass automates reply management by organizing responses, differentiating between genuine replies and auto-responders, and evaluating emails based on their tone. The Reply Project, aided by templates and ChatGPT, makes it easy to manage and respond to these replies efficiently.

Native Integration and Advanced Options

Gmass seamlessly integrates with Google Sheets and offers API, Webhooks, and Zapier for advanced automation and integration needs. This ensures that Gmass can fit seamlessly into your existing workflow and adapt to your unique requirements.

Tracker Blocker Chrome Extension

Privacy and tracking concerns are on the rise. Gmass addresses this by offering a Tracker Blocker Chrome extension. It prevents Gmass open tracking pixels from registering as “opens” on your tracking reports, enhancing privacy for both senders and recipients.

Unsubscribe Management

Maintaining compliance with unsubscribe requests is crucial for email marketing ethics. Gmass takes care of unsubscribe management, ensuring that no emails go out to people who have unsubscribed, helping you maintain a positive sender reputation.
