Users appreciate the ease of use and intuitive interface of the Sender plugin, particularly for email marketing, where it allows smooth send-outs and easy template building. The customer support, commonly praised for being quick, knowledgeable, and patient, is another strong point, with several users singling out individual support representatives for their outstanding service. The pricing is also considered very reasonable, offering good value compared to other more expensive platforms. However, users have encountered drawbacks, such as insufficient integrations (notably with Salesforce), delays in sending automations, issues with SMS marketing setup, and technical problems like errors with WooCommerce and list management. Customer support effectiveness appears inconsistent, with some users reporting slow or unhelpful responses.
