Ask any successful course creator, and they’ll tell you that email subscribers are their biggest business asset.

Why? Because an email list allows you to build trust with your audience, share your marketing message, and drive repeat sales.

This is why email marketing has an ROI of $36 for every dollar spent.

But you can’t build an email list without the right list-building tools. The best list-building tools offer creative ways to engage your website visitors and persuade them to sign-up for your email list.

In this article, we’ll share some of the best list-building tools to help you convert your site’s cold traffic into subscribers and leads.

Let’s get started.

Use A Lead Magnet To Attract Email Subscribers

Before we dive into the best list-building tools, you need to understand that using these tools is only one part of the list-building equation.

Even the best tools won’t be able to attract many subscribers and leads if you don’t offer visitors something valuable to sign up for. 

This is where lead magnets come in.

A lead magnet is a free resource like an eBook, video training, free course, templates, checklists, or anything valuable that your visitors can access by giving you their email addresses.

Here’s an example of a lead magnet.

The best lead magnets offer immediate gratification and are valuable enough to attract your audience’s attention.

This is exactly why “Subscribe to our newsletter” is NOT an effective lead magnet.

So, if you want to get the maximum ROI from the tools we’re about to share in this article, make sure to use an attractive lead magnet on your site.

The Best List Building Tools To Capture Email Addresses

Let’s now take a close look at some of our favorite tools for converting your site’s cold traffic into email subscribers and leads.

4.   Interact

Interact is one of our favorite list-building tools because it provides you with a unique and highly engaging way to convert your website visitors into subscribers and leads.

Instead of using the conventional lead magnets like eBooks and courses, Interact allows you to create online quizzes that not only generate leads but also help you understand your audience needs and personalize their experience.

Here’s how it works.

Your website visitors see a CTA on your site asking them to answer a quiz.

When they complete the quiz, they’re required to enter their email address to get the results by email (plus sign up to your list).

For example, you can find out what type of quiz should you make for your online business by completing Interact’s Quiz Recommender.

What is your primary goal as a business owner? with 3 possible responses to choose from

Interact is an ideal list-building tool for online course creators for several reasons.

  • Its quizzes are engaging and immediately catch the reader’s attention.
  • The quizzes are interactive and easy to answer
  • They help you identify different subscriber segments to create tailored eLearning solutions.

The third point is critical for your business.

For example, if you’re an email marketing strategist, your site usually gets multiple visitor types such as prospective clients, freelancers looking to learn email strategy from you, and random visitors with no clear goal.

You can’t offer the same solution to all three.

Quizzes allow you to segment them at the list-building stage and offer them different solutions that satisfy their needs.

Interact Pricing

Lite – $27/month paid annually

Growth – $53/month paid annually

Pro – $125/month paid annually
