10 Best WordPress Optin Form Plugins (Most Are Free)

If you aren’t building an email list, you’re missing out on one of the most powerful and consistent ways to drive visitors and customers to your website or blog. From day one, Optin forms are a great way to generate more leads from the traffic you already get. It’s simple because once you set it, It works on autopilot.

When you start as a beginner, Two things are necessary:

1. An email marketing service solution
2. An opt-in form for users to genuinely opt-in to your list

There are enormous benefits to building an email list, some of which you already know. An email list like an asset. Once you have plenty of subscribers on your list, you can start with a series of autoresponders that will make more money every time you send them.

The best part, It’s all automated, which is why email marketing has become so important.

Now once you select an email service to start with, you may probably want to use the old, not so good looking, and lame HTML optin forms that come free with your email service. There’s nothing wrong with them except:-

• They look pathetic
• They don’t perform well
• They aren’t user-friendly and are not optimized for multiple devices
• They aren’t fully customizable

Everything which makes an optin form lesser effective comes with these pre-made forms. So, here’s the thing:

• You want to build an email list that converts
• You want an easy way to get more leads, thus more subscribers
• you want to make more money with powerful email marketing funnels
• and you want to do it fast.

Thankfully, WordPress users can choose from many different types of optin form plugins that are openly available. Out of so many plugins choosing the best one and that too without experimenting and brainstorming can be a daunting task.

So, This post will tell you about some of the best optin form plugins (free and premium) that you can use right away to get more email subscribers from your WordPress blog.

If you haven’t started list building yet, check out our detailed tutorial on how to start an email list.
