Features of Optin Ninja

The Optin Ninja plugin is certainly packed with features that are all focused on increasing the number of visitors to your website who sign up and join your email subscriber list.

The features of this plugin are all centred on making it as easy as possible to create these high converting squeeze pages, which are often referred to as landing, or optin pages.

One way that the pages you create will stand a good chance of increasing your existing optin rates is through the use of a two-step sign up process. While it’s an optional feature of this plugin, the two-step optin process has been proven to increase conversion rates and works by requiring the user to click on a button, before the optin form is displayed. This is opposed to the traditional method of simply displaying the form on your pages.

Optin Ninja also includes an A/B testing tool which allows you to compare and test different versions of your squeeze pages to find out which one is more effective at turning your visitors into subscribers. By using this feature you can constantly optimize your content to find the highest converting variations, and get the best return on your investment.

If you are looking for an effective way to either start building your list of email subscribers, or improve your existing efforts, then the Optin Ninja plugin could be just the tool you need.

Using Optin Ninja to Grow Your Subscriber List

Once the plugin and any add-ons have been uploaded and activated on your site, the tools can be accessed from the Optin Pages item on the Optin Ninja menu on the admin sidebar of your WordPress dashboard.

Optin Ninja Pages

To help you get started the plugin includes two sample pages which you can take a look at to get a better understating of what Optin Ninja can do and how it works.

The demo pages include the two-step optin forms so you can see them in action and get a good overview of how they work.

Optin Ninja Demo Step 01

When the visitor clicks on the button, the optin form is displayed, giving them the opportunity to sign up and join your email list.

Optin Ninja Demo Step 02

Depending on how you’ve configured the boxes, the second box, which contains the form could be displayed in a new page, or through a lightbox popup window.

If you want to modify the demo pages you can do so by clicking on the edit button. Alternatively, if you want to create a new page, then clicking on the Add New Optin Page will open up a blank canvas.

Creating a New Optin Page

If you do decide to create a new optin page, the first step is to give it a title, and then enter a custom URL which will be the address of the page.

Optin Ninja Create New Page 01

When setting up the new page you can enable A/B testing which will allow you to compare two similar versions of the same page to see which one performs the best. When using this feature you could compare images, wording, or any elements of the pages you like.

Through the settings of the page you can also enable Google Analytics integration for advanced tracking, choose to discourage users from leaving by using a browser popup with a custom message, and add any necessary custom HTML head code.

The options that allow you to customize the appearance of the pages give you the ability to:

  • Set a background image (full screen or tiled)
  • Use a slider to display multiple background images
  • Configure the slider animations
  • Select the background colour
  • Customize the message boxes and forms

Included Images

As the plugin comes with over 300 background textures, which can be imported from the settings page, you have plenty of options for choosing the right image for your optin page, out of the box.

There are also 35 HD background images which can be imported into your media library at the touch of a button, giving you even more options.

Once you’ve set the background image, you can then move onto crafting the first and second content boxes for your two-step optin forms. However, if you want to use the more traditional approach of just displaying an optin form without the first step, then you can easily disable the first content box.

To make creating the content boxes as easy as possible, the developers of this plugin have used the default WordPress post editor to allow you to create the content.

You also get access to a set of easy to use controls for customizing other elements of the forms. This includes the appearance of the box, such as colours, fonts, and borders, as well as the styling of the button.

If you aren’t using a third party email newsletter service, this plugin gives you the ability to send out a welcome email to new subscribers, providing you are storing the collected emails in your site’s database.

Once you have created your optin page you can then preview it like a regular WordPress post or page, or publish it to start using it. After publishing the page, it can be accessed via its own URL which you can use to link to from elsewhere in your site, or even set it as the homepage for your website.

View Your Optin Page Statistics

Optin Ninja includes a reporting tool for viewing the statistics of your optin pages. These stats display the number of unique views for each of the two boxes that make up a page, as well as the conversion rate.

Optin Ninja Stats

If you are carrying out any A/B testing or you are using multiple optin pages on your site, these statistics give you an easy way to see which ones have the highest conversions rates, helping you to optimize the other optin pages on your site.

Email Marketing Service Integration

When it comes to storing the email addresses that this plugin helps you collect, Optin Ninja gives you the option of simply storing those contact details in the backend of your site.

Optin Ninja Subsribers

These subscribers can then be exported as a CSV, Excel, or PDF file for use elsewhere, such as an email newsletter service when you sign up for one.

However, Optin Ninja also integrates with a number of the most popular email marketing services, such as:

  • ActiveCampaign
  • Aweber
  • GetResponse
  • Mad Mimi
  • MailChimp

This means whether you have an account with a supported auto responder service or not, you can still start collecting email addresses and building your subscriber list as soon as the plugin goes live on your site.

Add-ons for Optin Ninja

So far there is only one add-on for Optin Ninja available but there are others in the works.

The available extension is the auto popups add-on which allows you to display your optin pages in lightbox popup windows, based on numerous filters and triggers.

The settings allow you to filter users that are already subscribed, limit the number of times each user can see a popup, and decide when and where to show the popups.


As this add-on is available for just $5, it makes a great upgrade for this plugin.

Optin Ninja Pricing

Optin Ninja is a premium plugin, but it’s an affordable one that can be yours for just $28. When you compare this plugin to some of the other landing page building tools or premium optin form builder plugins for WordPress, it is a good value option.


The Optin Ninja plugin is a cost effective and easy way to start creating custom landing and squeeze pages for your site. If you are looking for a powerful way to increase the number of email subscribers on your list, that also gives you some more tools than a standard optin form plugin, then Optin Ninja should definitely be considered for your site.

With lots of customization options and split testing, Optin Ninja should be able to help you increase your signup conversion rates in no time at all.
