Wisepops comes with four channels—

Website popups, bars, embedded signup forms, and onsite notifications, so you can create pretty much any lead capture form for your website (and be able to add it where you need).

Thanks to customization, this gorgeous popup design looks like a natural part of Blume’s website.

One feature of Wisepops that makes it stand out among the best email capture tools is onsite notifications.

It’s a feed that acts like a personal inbox on a website. You can add a signup form there, of course, and generate leads, like here:

The feed can help you boost email list building and client acquisition.

2. Sumo

optinmonster

Sumo is arguably the best free email capture software out there. You can create, customize, add email signup forms for free to your website, and even choose which audience will see them. But if you generate over $500 with Sumo, you’ll need to upgrade.

Still, not too bad if you need an email capture app to get started with lead generation.

Highlights:

  • Simple and customizable email capture forms

  • Discount codes in forms

  • Visitor group targeting

  • Built-in email marketing app

  • Analytics

Cons:

In the free version, statistics for email capture forms are available only for 30 days.

Who is Sumo for?

If you’re a startup or a very small company that needs to build an email list, Sumo should be a worthy email capture tool for you.

Pricing: 

You can use Sumo for free until the app helps you generate $500 in sales. After that, you’ll be required to pay $39/mo for a premium subscription.

klaviyo

Besides being a popular email marketing app, Klaviyo also boasts a suite of lead capture forms. You get all the features you need to capture emails, make customer surveys, and announce your sales and special offers.

Highlights:

  • Popups, embeds, fly-outs, and teasers

  • Drag-and-drop form customization

  • Targeting based on visited pages, activity, and more

  • Multi-step forms

  • A/B testing

Cons:

Klaviyo is more of an email marketing app with a decent built-in email capture tool. User reviews say that it can be overwhelming even if you have marketing knowledge because of the numerous flows and segmentation options—that’s why beginners should look elsewhere.

Who is this email software for?

Large ecommerce businesses that need an email and SMS marketing app and an email capture software in one.

Pricing: 

Klaviyo is free for 500 monthly email sends. Paid plans are starting at $30/mo for 1,000 subscribers (the more subscribers you have, the higher the price is).

wpforms

If you need to build your email list on a WordPress site, consider WPForms. As the name suggests, this plugin was built for this platform. But it’s not a simple plugin, though, as you get user segmentation, form abandonment, and other advanced features.

No coding knowledge is needed to use this lead capture plugin.

Highlights:

  • Decent set of features: newsletter, survey, payment, and contact forms

  • Use a vast library of pre-made email capture form templates

  • Dynamic forms that change depending on what visitors choose

  • Embedded signup forms

  • Available in 14 languages

Cons:

The free version is pretty underwhelming, as you can get only a few email capture form templates to make use of.

Who is WPForms for?

The majority of users are WordPress sites—digital marketing agencies, blogs, and consulting companies.

Pricing: 

The most affordable plan costs $49/yr (for one website). Note that this email capture tool has only annual pricing.

leadpages

This email capture software is helpful if you’d like to create custom landing pages and simple lead capture forms on your website. According to users, LeadPages is especially effective when trying to get visitors to sign up for a software demo, a lead magnet, or get in touch with a sales team.

Highlights:

  • Landing pages & popups

  • Blog sidebar that turns into an email capture form when clicked

  • On-click popups for blog author bio links

  • Time- and behavior-triggered popup forms

  • Landing page templates with build-in popups

Cons:

LeadPages is first and foremost a landing page building software, so it misses some of the important lead capture features like mobile popups.

Who is LeadPages for?

Online businesses that need to convert their traffic with landing pages.

Pricing: 

The pricing for this email capture software starts at $49/mo.

Email capture software: summary

Picking the best email capture app can be a bit confusing. There’s a lot to consider, obviously, but I hope this list gives you a better idea of how to make a good choice. 

If you still need some advice, let me recommend our own email capture app, Wisepops. It’s perfect for ecommerce websites and has all the features you need to build an email list quickly, and engage traffic consistently thanks to targeting.

If you need a dedicated WordPress plugin, though, OptinMonster and WPForms are great options. Both were developed first and foremost for WordPress-powered websites.

LeadPages is obviously the best email capture app on this list if creating landing pages is your goal. But if you’re a startup trying to get started with generating leads, then Sumo could be a great way to go.
