10 Best Lead Capture Tools For List Building in 2022

Last update:

Lead capture tools are plugins or online services that collect email addresses from your visitors and add them to your subscriber list.

They are essential for building a list. A list of subscribers is a vital part of any online business for various reasons.

Why You Need a List

Here are some of the reasons you need an email list if you’re running an online business.

Bring your visitors back

Left to their own devices, only a small percentage of your visitors will ever come back to your website.

And that’s bad news if you’re trying to build an audience or a following.

Most of your visitors will have to be exposed to your message about seven times before they are ready to buy.

That means you need to bring your visitors back to your website, again and again.

And the only way to do that is if you have their email address.

In other words, you need to capture the email addresses of your visitors and build a relationship with them, through regular email updates, over a period of time.

You own your list

Think about all the ways you generate traffic to your website: Facebook, Pinterest, Twitter, Instagram, and Google Search. None of those platforms belong to you.  

They could take your account away tomorrow and your traffic would dry up overnight. Or there might be an algorithm change. Boom! Your traffic’s gone.

An as online marketer, the only source of traffic that you own is your list. And that’s one reason why every online business should be building their list from day one.

Highest return on investment (ROI)

Email marketing gives the highest return on investment (ROI) of any form of marketing.

A study by McKinsey & Company shows that email is nearly 40 times more effective than Facebook and Twitter combined in the acquisition of customers.

And the Direct Marketing Association reports that on average, email marketing produces a 4300% return on investment.

Top 10 lead Capture Tools

With a lead capture tool – otherwise known as an optin form that collects email addresses from your website visitors.

Here are the top 10 lead capture tools with a brief description of what each one does, its main features, and pricing.

#1. Hello Bar

Hello Bar is a narrow horizontal strip that sits at the top of your web page and invites people to join your mailing list.

Like a Feature Box it has an advantage over popups and slide-ins: it is always there. And that means more opportunity to get a sign-up from your visitor.

The free version carries the Hello Bar branding but it’s fairly unobtrusive (a small icon in the left side of the bar).

With the paid version, you can remove the ‘Hello Bar’ branding and you can create different bars (with different messages and different email capture forms) for different pages.

Boxzilla (previously called ‘Scroll-Triggered Popup’) is a lead capture tool that’s been around for a while.

The templates that come with Optin Monster are as slick and polished as you’ll find anywhere.

There’s a Visual Editor that allows you to customize the templates – you can use it to make minor adjustments or completely re-design them.

As I mentioned earlier in this article, while popups are highly effective, a lot of people find them very annoying.

Optin Monster has some nice features that will make your popups less irritating to your visitors:

  • Exit intent – popup only shows once your visitor moves the cursor off the page towards the ‘back button’.
  • Scroll trigger – popup only appears once your visitor has reached a certain point in the page.
  • 2nd page view option – popup won’t appear until visitor has viewed two pages of your website.
  • Hide popovers from subscribers – people who have already given you their email address won’t see a popup again.
  • Cookie expiration – you can use this to ensure that a visitor won’t see a popup again until a specified number of days have elapsed.


  • Basic – $9 p/month
  • Plus – $19 p/month
  • Pro – $29 p/month
  • Growth – $49 p/month
