In case you didn't know, email usage is at an all-time high. More than 3.7 billion people use email worldwide.

With email usage so high, it's no wonder you probably constantly receive marketing emails from businesses. Email marketing works — even in the B2B space.

In fact, 86% of B2B marketers rely on email marketing campaigns to promote new business, which begs the question — are you using email marketing effectively for your business?

More importantly, are you using email marketing consistently at all?

There are a ton of email marketing service tools out there to help you with your email marketing, some of which are completely free. But, it's important to note, not all free email marketing tools offer the same features.

As someone working for a new business, you're probably most concerned with how many emails you're able to send, which features you have access to, and whether you can upgrade your account as your business grows.

You're probably also thinking about deliverability, and whether your emails will be consistently delivered to your contacts' inboxes. Plus, you likely want a tool that's both easy-to-use and doesn't require advanced technical skills.

Fortunately, we have you covered — here, we've ranked the best free email marketing tools that you can use for your business in 2020.

Using the CRM, you can include personalized content in your emails, like first name and company name, to ensure your contacts feel like they are being personally addressed, all while tracking email activity in the CRM. This contributes to efficient scaling opportunities should your business outgrow the free tools and require more robust automation features, such as workflows.
