What Are WordPress Opt-in Form Plugins?
An opt-in form is a feature on a website that allows visitors to subscribe to your email list.
The word “opt-in” means that the visitor says it’s OK for you to contact them about your products and services.
Opt-in forms are an essential tool for any email marketer because they help you grow your list of subscribers.
Types of WordPress Opt-in Form Plugins
You can choose from five basic opt-in forms.
1. Pop-up Boxes
Pop-up boxes appear as a small box that pops up on the screen.
Many marketers choose to use it in the lower right-hand corner of a web page.
2. Modal Boxes
Modal boxes are similar to pop-ups, but they appear in the middle of the screen.
3. Slide-in Boxes
Slide-in boxes are opt-ins that appear as a small box sliding in from the side of the screen.
4. Sidebars
Sidebars are opt-ins that appear in the sidebar of a website, usually on the right side.
They can be static or they can scroll with the page.
5. Notification Bars
Notification bars are opt-ins that appear at the top or bottom of a website, usually across the entire width of the screen.
Why Use a WordPress Opt-in Form Plugin?
Typically, you’ll use an opt-in form plugin for two reasons.
Increase Conversions
The first reason to use an opt-in form plugin is to increase conversions.
A conversion is when a website visitor takes the desired action that you want them to take.
For example, if you have an eCommerce store, a conversion would be when someone buys something from you.
If you have a blog, a conversion might occur when someone subscribes to your email list.
Allow Visitors to Opt-in to Emails
An opt-in form allows a visitor to subscribe to your email list so that you can contact them in the future. It’s different from a general contact form.
In this case, the visitor specifically states that they want to receive marketing messages from you.
The benefit of this is that you can send targeted emails to people who already show an interest in your products or services.
It can lead to more sales and more customers because you’re only contacting people who want to hear from you.
How to Choose the Right Opt-in Plugin
Consider the following four factors when selecting your next WordPress opt-in form plugin.
1. Integration
You’ll want to make sure that the plugin integrates with your email service provider (ESP).
For example, if you use MailChimp to send your emails, you need a plugin that provides a built-in MailChimp integration.
That way, each new lead is automatically added to your MailChimp list.
2. Ease of Use
The best plugins have a user-friendly interface and provide step-by-step instructions.
They also offer customer support in case you run into any problems.
3. Performance
The plugin should not slow down your website.
A slow website can lead to lower conversion rates and fewer subscribers.
4. Flexibility
The plugin should be flexible so that you can customize it to match your branding.
For example, the plugin should make it simple to change the colors, fonts, and text of the opt-in form.
