Users appreciate the MailerLite plugin for its simplicity and smooth integration with WooCommerce, enabling effective automation and email marketing. They commend the support team for being responsive and resolving issues, albeit sometimes after significant delays. However, many users experience frequent disconnections and compatibility issues, particularly with WooCommerce, leading to disrupted sales and lost revenue. These problems often require creating new API keys and reinstalling the plugin, a cumbersome process. Some users also face legal concerns due to default settings that auto-subscribe customers without consent. Despite its ease of use and helpful support, the unreliable connection makes some users consider alternative email marketing solutions.
