I recently used MassInbox for a bulk emailing campaign, and the experience was far from satisfactory. Despite their claims of being the "world's first Mass Emailing Agency," the reality fell short.

The platform's user interface is clunky and outdated, making it a struggle to navigate through the entire process. The promised efficiency in sending thousands of emails daily turned out to be nothing more than a marketing gimmick. The sending speed was painfully slow, causing significant delays in our campaign timeline.
