11 Best WordPress Newsletter Plugins for 2021

Email marketing is an excellent way to improve your conversion rates. You can inform website visitors about news and promotions by sending them regular newsletters.

It will help promote your brand, eventually turning visitors into potential customers, increasing your revenue as a result. However, creating and sending email newsletters can be somewhat time-consuming.

Not only do you need to send regular emails to your subscribers, but they must also present relevant information for the recipient. In this case, having a WordPress newsletter plugin is very handy for optimizing your email campaign.

It can automate newsletter sending and help you segment your audience alongside other features. To make your decision process simpler, we have tested several newsletter plugins for WordPress to recommend to you only the best tools in the market.

Why Do You Need a Newsletter Plugin?

Email marketing is the practice of sending emails to prospects and customers. Typically, these emails contain sales promotions, new blog posts, or other relevant information you have to offer. 

An email newsletter can also be a way to ask for feedback and build trust with your customers. 

Other reasons why email marketing is essential for your business include: 

  • Nurturing leads. Through emails, you may offer coupons or free trials to attract users and convert them into subscribers or customers. This method is known as lead generation. 
  • Boosting customer loyalty. Make connections with your subscribers by using email newsletters to reward them with promotions or solve their problems by sharing informative content.
  • High return on investment (ROI). Data shows that email marketing generates an average ROI of $42 for every $1. Drive your subscribers to purchase your product or download your content with a strong call-to-action (CTA). 

However, having a WordPress newsletter management plugin will greatly improve your email marketing strategy.

Newsletter plugins allow you to create and send newsletters directly from your WordPress dashboard. Others focus on building eye-catching forms and pop-ups to attract more visitors and grow and manage your mailing list.

Since you will need two types of plugins to develop an effective email marketing campaign, our list includes WordPress newsletter and email subscription plugins.

Top 4 WordPress Newsletter Plugins
