Regardless of what type of business you run, creating an email list should be at the top of your to-do list. With your email list, you can share your story, promote your business, and showcase your products, amidst turning email subscribers into loyal customers. Any online marketer will agree that email is one of the most effective marketing channels. There is no doubt in the marketing world that building an email list is critical to your business’s success, but how do you actually collect email addresses on your website? In this article, we have rounded up the best email opt-in plugins on the market.

What is an email opt-in?

“Opting in” generally refers to email communication. An opt-in email list is a collection of email lists with information that your subscribers have willingly given to you. This means they are aware that you are adding them to your list and agree to receive mass emails, newsletters, or other forms of digital communication from you. You can see an opt-in form on most websites asking you to sign up for a newsletter or other marketing material. Optin forms can be displayed to users in a variety of ways. 

Most WordPress email newsletter plugins come with some kind of opt-in feature. But if you are using a solution that does not provide opt-in forms or you want full control over how your opt-ins look, there are many dedicated WordPress email opt-in plugins that can help grow your email list.
