The 11 Best Email Opt-in Plugins for WordPress
As a business owner, you probably know how effective email marketing can be. Almost every online marketer swears by its effectiveness, so it’s a channel you simply can’t afford to ignore.
Here’s the rub: 99% of all email users check their inboxes daily. That’s a staggering figure, and perfectly highlights the importance of using an email opt-in plugin. More importantly, 59% of respondents to a HubSpot survey stated that marketing emails profoundly impact their purchasing decisions.
However, finding the right email opt-in plugin can be a bit confusing. The sheer number of options can become a bit overwhelming for most people. Therefore we made this extensive comparison that makes it easier for you to find the best plugin depending on your needs.
Why Use Email Opt-in Plugins for WordPress?
An email opt-in plugin allows you to collect email addresses on your website, and send newsletters to them to nurture and grow your list. It’s a simple way of designing an email subscription form and testing it.
Many of the email opt-in plugins today come with A/B testing tools that you can use to gauge the impact of your email subscription forms and tweak them as necessary.
You don’t need any coding experience, since you can drag and drop elements to change the design of your form. Then, you should know that many of these email opt-in plugins come with an array of features that allow you to customize the forms too.
They don’t just have to “pop-in”, for instance. You can have a signup form slide into a webpage, it can be placed in a sidebar, or in a post. Many plugins also come with extensive support for analyzing the content of your emails as well, such as:
- Open rates
- Heatmap tracking
- Unopened rates
It goes without saying that if you are serious about building an email list, you need to use a decent plugin.

The Bottom Line
With so many different email opt-in plugins to choose from, it can be a bit difficult to make the right choice. You might want to list down a few features that you want, and then test the plugin through a free trial or a hosted demo.
It’s best to try out the plugin first, either through a hosted demo or via a trial version, before you decide to buy one. But remember, it’s not just the plugin that will get you more sign-ups for your newsletter; you also need to optimize the content for the best results!
