  4. Test the Plugin: To ensure that you select the best opt-in plugin for your website, it’s recommended that you test it out first on a separate test site or staging environment. This helps you better understand how the plugin works and whether it can effectively meet your needs. By testing the plugins in this way, you can confidently choose the best option for your website and avoid any potential issues or problems in the future.
