  • They look awful
  • They aren’t very good at their job
  • They are neither user-friendly nor optimized for multiple devices
  • They’re not completely customizable

Most importantly, these pre-made opt-in forms aren’t efficient in terms of features and customization. So here’s the deal:

  • You want to create a conversion-oriented email list
  • You seek a simple way to collect more leads, consequently more subscribers
  • You want to increase your returns using effective email marketing funnels
  • And you want all of this quick

This is where WordPress opt-in plugins come in. WordPress opt-in plugins offer conversion-oriented features, is easier to use and customizable, and have advanced features to enhance your lead-generation experience.

How to choose the right opt-in plugin?

Frankly speaking, simply choosing any WordPress opt-in plugin doesn’t guarantee you a great experience. Some plugins can easily become irritating, tarnishing both the user experience and the reputation of your brand.

Fortunately, WordPress users can choose from a plethora of open-source opt-in form plugins. Finding the perfect plugin out of so many options, especially without trying and brainstorming, can be a difficult chore. 

So keep these three things in mind while choosing an opt-in plugin:

Integration: The point of using a WordPress opt-in form plugin is to be able to capture leads and send them to your email marketing tool automatically. There’s no point in buying a tool that doesn’t integrate with your email marketing tool. So make sure to check out if the opt-in form plugin integrates with your preferred email marketing tool.

Ease of use: Be certain that the opt-in plugin you select is compatible with your WordPress hosting environment. Many opt-in plugins are poorly designed, hence their advanced features won’t work properly with the majority of modern caching solutions that your hosting company may be using.

Performance: As many WordPress opt-in plugins rely on WordPress to track data, this greatly increases the server load and causes your website to slow down. This is why you need a plugin that provides great conversion capabilities without causing any performance issues.

Flexibility: Finally, you should choose an opt-in plugin that provides features like behavioral interaction, targeting, and personalization, so you can provide the best user experience while also maximizing conversions.
