Marketing Strategy HotSocket worked with MHS to assess and select various introductory music offerings to generate new memberships. HotSocket tested a wide range of music selections, offers, creative variations, payment options, media units, and media channels in real-time. Execution HotSocket's first campaign for MHS was the Jazz Heritage Society. Within this music category, HotSocket tested a broad array of variables to determine the most effective sales drivers. HotSocket was able to eliminate any ineffective creative, offers, and sources, and focus only on those that yielded superior results. Following this campaign's success, the classical campaign was launched and, after some fine-tuning, that campaign was able to achieve an even greater level of success than its predecessor.
