For Stefan, who has identified specific zip codes for his target market, direct mail campaigns would likely be the best advertising option. This method allows him to directly reach potential customers in those specific areas with tailored messages, promotions, or offers, making it a cost-effective way to engage with his defined audience.
While social media advertising can also be targeted geographically, it may not reach those who are less active online or who may not use social media. Television or radio ads have a broader reach and might not be as targeted or efficient for a local market. Word-of-mouth advertising is valuable but may take time to build momentum, and it lacks the immediacy and direct reach that a mail campaign can provide.
