If you are using WordPress then sit back and relax. Because WordPress opt-in plugins are there to make your life easier.

Using these plugins you can instantly create stunning opt-in forms. I will show you some of the best plugins to add opt-in forms to your blog.

So let’s get started.

What is an Opt-in Form?

The opt-in form is a buzzword in the email marketing segment. An opt-in form is a user subscription form that encourages visitors to put email addresses and some other details. Some of the common form fields include name, email, phone number, company, etc.

In exchange for users’ contact information business provides free resources and exciting offers. The brand uses this method as a genuine way of collecting email addresses. Instead of sending emails blindly, you can send interest-based emails to customers who want to hear from you.

Opt-in can be divided into two parts:

  • Single opt-in
  • Double opt-in

Single opt-in directly adds the email to the list when a user fills out the form. It is the easiest type of form and collects more emails. But you never know the authenticity of emails.

Double opt-in requires two-step verification. The user will receive a confirmation email having a hyperlink. The email address will not be added to the list until the user clicks on that link.

Email opt-in forms allow you to collect emails quickly and more effectively.

Using the email database you can create drip email campaigns to drive more sales and leads. Create a different email list and segment your audience based on the behaviors or activities. Keep your audience engaged with your business and send relevant emails.
