Are you looking for the best combination of list building tools to grow your email list FAST?

Growing your email list is never easy. But, like everything in life, you can save yourself hours of time, energy, and headaches if you’re using the right tool.

That’s why, in this post, we’re going to share 9 of the best list building tools that you can use to increase email signups.

But before we get started, let’s get clear on why it’s so crucial to grow your list in the first place.

Why Use List Building Tools

Some blog posts and marketers love to push the idea that “email marketing is dead.”

But nothing could be further from the truth. In fact, email marketing is still your best bet for consistently guiding your audience down a sales funnel and driving more revenue.

That’s because it’s the only platform that gives you total ownership of the conversation.

Other marketing strategies, like social media or pay-per-click (PPC), are definitely valuable. The only problem is that they leave you vulnerable to algorithm changes that can affect the campaign’s success.

With email marketing, you don’t have to worry about any of this.

Once you have a robust list to work from, you can send email campaigns whenever you want for:

  • Company updates
  • Product launches
  • Product updates
  • Webinars
  • Promotions like coupons or free shipping

Or any other type of email that will help scale your business.

The only problem? Growing an email list can be tough.

Now more than ever, people are hesitant to hand over their personal contact information. That’s why you need the right tools to help build trust with your customers and make them offers they can’t refuse.

Let’s turn our attention to 9 of these list building tools.

9 List Building Tools to Try

All the tools on this list are incredibly powerful and were built to help companies get more email subscribers. Some of them are specific to WordPress, while others can be used for any website.

We’ll indicate which ones are strictly WordPress plugins and which ones can be applied to different platforms.

That way, you can find the right tool for your unique needs.

Let’s get started.

1. OptinMonster

OptinMonster is hands down the world’s best list building tool. It allows anyone to quickly and easily build optin campaigns to grow their email list.

By “optin campaigns,” we’re referring to things you’re already familiar with, like popups, floating bars, fullscreen welcome mats, and more.

Plus, with its drag and drop editor, OptinMonster lets anyone create professional and high-converting campaigns in a matter of minutes.

It all starts with selecting one of 50+ pre-built templates for the campaign you want to build:

Once you’ve chosen the right campaign, you’ll want to make a few minor modifications. That’s because your lead magnet will change depending on your target audience.

Fortunately, making changes to your OptinMonster campaigns couldn’t be easier.

To modify your campaign’s text, for example, you would simply make changes with the inline editor:

This gives you 100% control over things like:

  • Font family
  • Font size
  • Color
  • Alignment
  • Line height
  • And much more…

But what if you want to add a new feature to your campaign? That’s not a problem – even if you don’t have any design or coding experience.

New features can be added with a drag and a drop:

This lets you add different functionality to your campaign, such as adding:

  • Videos
  • Images
  • Custom text
  • Chatbots
  • Countdown Timers
  • Custom HTML
  • And more…

But once you have the campaign designed, you’re only halfway done. That’s because you’re still missing one of the most important steps to capturing emails: displaying the campaign to the right people.

For that, you’ll need OptinMonster’s powerful targeting rules that let you determine when, where, and to whom your campaign displays.

A few of OptinMonster’s most popular targeting rules include:

  • Exit Intent® Technology: Display campaigns as users are actively leaving your website.
  • OnSite Follow-Up Campaigns®: Show fresh campaigns to returning visitors to avoid “popup fatigue.”
  • Geolocation: Present offers to your site’s traffic depending on where they’re physically located.

These are just some examples, though there are many others.

But now you may be wondering, “This all sounds good… but do these targeting rules actually work?

OptinMonster is the list building tool that allowed Crossrope to explode its list by over 900%.

It’s also how ShotKit was able to start adding 40+ NEW leads every single day.

I hate popups, so I was hesitant to try one on my site. But the results from OptinMonster exit-intent popup speak for themselves. I doubled my subscription rate immediately without annoying my users. I haven’t had a single complaint. My only regret is that I didn’t start using OptinMonster sooner. I can only imagine how many subscribers I could have added to my email list! If you have a blog, then I highly recommend you start using OptinMonster. I’ve researched them all, and it’s the best in market.
