A superb list building plugin like Thrive Leads is armed with an array of endlessly customizable opt-in form types. You can use this plugin to add opt-in forms like:

Lightbox (=pop-ups)
Exit intent popups (desktop only)
Ribbon (same as Hello Bar)
Scroll Mat (Welcome Mat)
In content
In content and footer opt-in form
Screen filler
Slide In
Opt-in Widget

Once your form is created, you can conveniently designate which pages or posts these opt-in forms would be shown on your website.

Ribbon-type Form

This is a Form Design type called "Ribbon". It is displayed on the top of the page and it's usually a long horizontal bar. The content of the page will be scrolled down with the same amount as the ribbon's height.

The ribbon will always stay on top, even when the user scrolls the page. Good for narrowly targeted offers for subscribers and engaged visitors. Does not interrupt article reading.

Lightbox

A lightbox is an overlay that goes over the website and shows an opt-in form or a picture, etc. They call the user’s attention in a way that is impossible to ignore, because it darkens the rest of the page, but you can still see your site around the edges.

Screen Filler Lightbox/Overlay

Similar to the other type of lightbox, however it covers the entire screen. It is not considered best practice on mobile.

In-line and Post Footer

"In content" Opt-In forms appear automatically in the content of a post.

Note that this form doesn't have any width settings. It will expand to the full width of the content area of your theme

A "Post footer" opt-in box appears after each post.

Slide-in

A slide-in is a more friendly alternative to a pop-up. The box comes in with a slow animation from the side.

Scroll Mat

Essentially just an overlay (like the lightbox), so no harmful effects on Google search indexing!
Good for welcomes, lead generation, product offers, social media promotion and things you want to show visitors before they browse your site
As big and attention grabbing as a screen filler, but often perceived as being less intrusive

Two-Step Forms

Thrive Leads also has two-step templates like this one, similar to the one that Neil Patel was using.

Default state

Under "Animation & Action" you can designate what happens when you click on one of the forms. In the above case, when you click on the red button, the form closes, while the green button is set to switch to the below State 1 form. (You can also designate to open a landing page instead.)

State 1

Making Your Forms Responsive

It is important to verify that all your forms look good both on desktop and mobile, and even on tablet. An image that looks great on desktop may be blocking the rest of your message on mobile.

Thrive Leads already has the option to show a specific form on desktop and hide it on mobile, then create a different form for mobile. The editor also has separate previews to desktop, tablet and mobile.

However with Thrive Architect, you can modify each form to look good on any screen.

Thrive Architect features the most advanced mobile responsive editor for WordPress. Then, you can start to edit and tweak your form to make it look good on each and every size.

This means you can for example:

Hide images on mobile
Make text smaller or larger depending on the screen size
Hide complete “blocks” from your mobile or tablet forms

On the above screenshot you can see a mobile version preview where the image has been taken out.

Thrive Leads Integrations

Thrive Themes is ready to connect to 40 tools for email marketing, email delivery, webinar, spam prevention and more. Take a look through the list to see their available API integrations. Click on the link and you will find not only the complete list, but there is also a separate video showing how to connect each service through an API key.

The advantage of connecting through API is that you only need to connect once. Afterwards, when you set up a new lead generation form, you can select the connection from your Edit screen.

One of the services you can connect is Google Recaptcha, giving your forms spam protection.

It is also possible to connect the same opt-in form to multiple services. As an example, you can even have your visitor sign up to your email list and create a WordPress account at the same time, straight from the opt-in form. (Not recommended though, just because it’s too many actions at the same time and chances are your subscriber will miss one of your notification emails.)

There is also connection to GoToWebinar, WebinarJam, Zoom, Facebook, Twitter.
