WordPress email marketing plugins

According to Oberlo, for every $1 spent on email marketing, the return is $42. That is quite an impressive return, especially in today’s highly competitive world where a marketer needs the highest possible return on investment (ROI).

However, to take advantage of this lucrative marketing strategy, you need the assistance of the best email marketing plugin for WordPress.

Now you might be wondering why we are just focusing on WordPress email marketing plugins and not any other platform. The reason is that WordPress is the most popular platform in the world

Let’s have a much more detailed look into WordPress and why you should prefer it over other  CMS.

Why WordPress?


WordPress is the most popularly used CMS across the internet globe. It has a 60.4% market share to its name, which means that around 33.5% of all active sites use WordPress as their CMS. 

The United States, the United Kingdom, and Russia are the top three countries using WordPress CMS and we have more than 35 biggest and most popular brands that have opted for it, including TechCrunch, The Wall Street Journal, Beyonce, etc. 

The process is fairly easy and hassle-free for anyone looking to build a website or online store on WordPress. All you have to do is download the free software from WordPress.org and buy a domain name with a WordPress host. 

Easy customization with thousands of free templates and plugins to choose from makes website management and design on WordPress the easiest. 

What is a WordPress plugin? 


For WordPress beginners, a plugin is an addition to their vocabulary. It is a term frequently used when we talk about WordPress CMS and it is only sensible to have a thorough understanding of it before we proceed. 

 A plugin for WordPress or any other CMS is a piece of software for added functionality. They are a stash of coded language that you “plugin” to your WordPress site to get better features, customization options, and improved functioning. 

Fortunately, enterprising developers have created thousands of free plugins that can work with minor tweaks and changes. You can use them to create a fully functioning e-commerce store, a social site, or a forum among other things.

You can download the free plugins available on the official WordPress plugin directory to perhaps add an Instagram feed link to your website or help improve its search engine ranking on Google.

Why use WordPress Email Marketing Plugins?


Now we know the advantages of WordPress over other platforms, let’s dig into another pertinent question. 

Why email marketing? Won’t we get a much better ROI from social media marketing or other forms? Who reads emails nowadays?

To answer all these questions, let’s have a look at some facts. 

According to Radicati Group, around 2.5 billion people worldwide use emails and there are about 196 billion emails sent across daily. This number of email senders is expected to increase up to 2.8 billion in the next two years. 

Out of the total emails sent, a massive 109 billion emails are business emails. If those figures are telling you anything, it is that emails are extremely popular today. 

They are a powerful tool to connect which is why, so it only makes sense that businesses today employ them as a primary marketing strategy.

Email marketing is the strategy of reaching out to your potential customers to engage, influence, and make them want more. There are numerous benefits of email marketing if it is done correctly. 

Much more effective than social media

Research has proven email marketing to be more effective than social media. It can be personalized and customized, is more action-oriented, economical, measurable, and mobile-friendly. 

Going into detail, there are various other advantages of using compelling email marketing tactics that we can discuss later sometime. 

While it is true that the Return on Investment (ROI) of email is far better than that of social media marketing, it doesn’t underplay the other forms of digital marketing channels. 

So, coming back to the topic; let’s explore the ten best email marketing plugins for WordPress which you can integrate into your WordPress website in a bid to improve your turnover.
