If you’ve landed here, I bet you’re asking yourself one burning question: What is the best cold email platform to send emails from? Well, my friend, you’ve come to the right place. As you already know, cold email is one of the most effective ways to get new customers for your business and to keep your sales pipeline stacked with new, piping-hot leads at all times.

In the last 6 years, we’ve sent out 1000s of cold emails – testing almost all the cold email software tools in the market. And let me tell you, choosing the best cold email software isn’t just about picking the tool with the slickest design or features.

It’s about finding a tool that supercharges your outbound efforts, multiplying success rate and creating a ripple effect on your sales strategy. Nothing that feels quite like it, right?

That being said, today we’ll explore the 10 best cold email platforms for B2B businesses, comparing their features, use cases and pricing options. By the end of this article, you’ll be able to get a fair idea of which tool would work best for you, without having to sift through each of them manually.

So let’s get started.

What to Look for When Evaluating Cold Email Tools?

Before you get down to choosing the email outreach tool of your choice, it’s important to understand the type of features it should have. Many business owners end up focusing on just one aspect, losing sight of the bigger picture when it comes to using cold email. 

Here are a few “must-have” features for any B2B cold email marketing platform: 

  • Deliverability: Email deliverability is one of the most important factors in 2024, especially when it comes to doing cold outreach at scale. After all, deliverability is what ensures that your finely-crafted, hyper-personalized emails actually reach the prospect’s inbox. With spam laws getting stricter, you must choose a tool that improves email deliverability while also maintaining a healthy sender score. 
  • Inbox Rotation: Next up on our list of must-have features is inbox rotation. This clever mechanism ensures your emails are sent from multiple inboxes, preventing you from being flagged as spam and maintaining your deliverability health. When you’re sending cold emails in large quantities, this feature becomes as essential as a compass for a mariner.
  • Sending text-only emails: Third on the list is the ability to send text-only emails. Now while B2C email marketing focuses on creating a blissful visual experience for the customer, it’s different for cold outreach. Adding HTML templates, pictures or GIFs won’t increase the chances of a response. On the contrary, plain-text emails look more natural to the spam filters. If you want to avoid landing in spam, choose a tool that lets you send plain-text emails as well. 
  • A/B testing: Cold outreach, at its core, is essentially a series of mini-experiments testing the effectiveness of your email to get a response. This is why having A/B testing functionality is critical for the cold email software you choose.

    A/B testing helps in standardizing these experiments at scale, helping you fine-tune your strategy based on tangible numbers. By tracking the performance of each campaign, you can make more informed decisions, double down on the best-performers and scale them further. 
  • Dynamic Personalization: Dynamic personalization in cold emails is the practice of automatically customizing each email based on the recipient’s specific information or behavior. It’s an advanced technique used to increase engagement, relevance, and ultimately, the effectiveness of your email campaigns.

Now, dynamic personalization can be as simple as inserting the recipient’s first name into the email greeting. But it can go much further than that, with emails referencing their specific industry, recent company news, their role in the company, or even content they’ve recently interacted with on your website. 

  • Inbox warming: Think of it as a trust-building exercise between your email server and ISPs (Internet Service Providers). When you first start sending cold emails from a new domain or email address, ISPs are naturally suspicious. This is where inbox warming helps – on ramping up the volume of emails from your account after starting slow initially. 

The best cold email platforms understand the importance of this feature and usually automate this process for you, ensuring your domain warms up in a way that doesn’t ring any alarm bells, and your emails land in the recipient’s inbox, not the spam folder.

  • Automated follow-ups: Next up on the roster, we have automated follow-ups. 

As you already know, the money is often in the “follow-up”. Yet, less than 3% companies send a follow-up email to their customers. Now, I don’t know about you, but I’d rather spend my time crafting powerful, persuasive emails than be stuck in the never-ending loop of remembering to send follow-ups. And let’s face it, in the world of cold emailing, following up is not just important – it’s vital.

Many email outreach tools let you set up a sequence of follow-up emails, often triggered by recipient behavior like unopened emails or no reply. When done right, these timely, automatic nudges can transform your cold leads into paying customers.

  • Merge tags: Merge tags in cold emails enable customization, making each recipient feel uniquely acknowledged. They allow insertion of personal details like the recipient’s name, company, or industry. When used correctly, this personal touch can make the recipient feel seen, and not like just another entry in a database. 

Some common examples of merge tags include: {{First_Name}}, {{CompanyName}}, {{IndustryName}} and so on. 

Don’t add too many merge tags as that can sound artificial. Make sure you strike the right balance and choose cold email software that offers this feature. 

  • Custom domain tracking: Custom domain tracking is all about keeping your brand consistent and trustworthy. Normally, when you send emails using a cold email software, the tracking links (used to track opens, clicks, etc.) are hosted on the software’s domain. 

This can raise red flags with savvy recipients or strict email filters, potentially impacting your deliverability.

However, with custom domain tracking, these links are hosted on a subdomain of your website. This makes emails appear more consistent and trustworthy, increasing your chances of landing in the inbox.

  • Email engagement analytics: Email engagement analytics provides a comprehensive view of your campaign performance, including open rates, click-through rates, and reply rates – metrics which improve your campaign’s success rate. Low open rates could imply the need for better subject lines, and low reply rates might indicate your call-to-action needs work.

Essentially, email analytics are a feedback mechanism offering constant insights to refine your strategy. 

So, ensure your cold email software delivers detailed, actionable analytics. They aren’t just for tracking success, but for forging it.
