12 Best Email List Building Tools to Grow Your List in 2024

Table of Contents

Email marketing is still one of the most effective ways to increase sales, allowing you to send special offers, interactive content, and updates about your products directly to consumers.

Checking email is a daily habit for most of us. And ecommerce stores can become a part of this routine if their email subscribers get used to seeing and opening their marketing messages. In fact, a whopping 50% of people buy from marketing emails at least once per month!

It’s clear that building a huge email contact list should be a priority. To do that, you’ll need to find a good email list-building tool. List-building software helps you collect email addresses via landing pages, opt-in forms, and lead generation popups.

In this article, we’ve collected 12 of the best email list-building tools out there. When used properly, these marketing tools can bring in a steady stream of new leads.

Let’s get started on finding a great list-building solution!

How to capture email addresses and build a list?

There are many list-building strategies that can boost your lead generation rate. These options include using dedicated landing pages to capture email addresses, embedded email opt-in forms on your website, and popups that display an opt-in form.

These are all great ways to build an email list, and we suggest using a combination of these proven tactics. 

But what’s the best way to generate high-quality leads?

Remember, it’s not all about size. Sure, a massive subscriber list is great, but what’s even better is a massive list that only contains interested, engaged subscribers. Suppose you’re looking for a list-building method designed to attract lots of people who are genuinely interested in what you’re offering. In that case, there’s only one way to go: displaying relevant, personalized messages.

Personalized popups work much better than simple inline forms, because you can precisely target people with great offers at just the right moment. They also help to focus the visitor’s attention on a single, enticing offer, thereby simplifying the decision-making process.

Our studies show that the average popup conversion rate is 11.09% (and that the top 10% are converting at around 42%, on average). Those astonishing numbers are the result of brands that create well-timed popups that are perfectly optimized for lead generation and grab their visitors’ attention. It’s difficult for embedded forms or landing pages to achieve conversion rates like these. 

Exactly which types of popups you should use to collect email addresses will depend on your brand and what your website visitors respond to.

You have lots of options, including welcome popups, exit-intent popups, discount popups, and lucky wheels. Check out this article for an overview of all the types of popups out there.

What’s the best list-building tool?

Our picks for the top 12 list-building tools primarily include software with a popup tool, because we truly believe that’s the best way to grow your list quickly. 

However, some of the tools offer other list-building solutions as well, in case you’re interested in improving your landing pages or other list-building tactics.

Email list builder best practices

Building an email list is crucial, but doing it right is even more important (especially if you’re building a list from scratch).

Here are some best practices to keep in mind when you build an email list:

1. Permission-based list building

Always ensure that your new subscribers have explicitly opted in to receive emails from you.

This not only builds trust but also keeps you compliant with marketing regulations like GDPR and CAN-SPAM.

Use double opt-in methods to verify email addresses and confirm interest.

2. Segmentation and personalization

Segment your email list based on user behavior, demographics, or interests.

This allows you to send personalized content that resonates with each segment, increasing engagement and conversion rates.

3. Popups

Popups can be incredibly effective if used wisely.

Experiment with different types, such as timed popups, exit-intent popups, and scroll-triggered popups. Ensure the offers on your popups are compelling. A/B test different messages to see what works best.

Here are some popup templates that can you build an email list:

4. Use humor and creativity

Incorporate humor and creativity in your CTAs to make them more engaging and less intrusive. A witty or playful approach can grab attention and encourage sign-ups.

For example, instead of a bland “Subscribe now,” try “Join the cool kids’ club – sign up today!”

5. Gamification

Add an element of fun to your sign-up process with gamification techniques like spin-to-win popups or quizzes. This makes the process interactive and engaging, encouraging more visitors to subscribe.

Get started with this lucky wheel signup forms:

6. Landing pages

Create multiple, targeted landing pages for different audience segments. Each landing page should have a clear and compelling CTA, tailored to the specific needs and interests of that segment. This targeted approach can significantly boost your engagement rates.
