There is no one-size-fits-all answer to this question, as the cost of a newsletter plugin will vary depending on the size, features, and popularity of the plugin. However, many free newsletter plugins are available on the market.
Some of the most popular free newsletter plugins include MailChimp’s Newsletter Builder and Weebly’s Newsletter Builder. These plugins allow you to create custom newsletters with ease, and they offer a variety of features, such as customizable templates, email opt-ins, and email marketing tools.
Overall, it is generally safe to say that newsletter plugins are free. However, the cost of individual features and plugins will vary, so it is important to review each plugin’s features before signing up.
