What type of advertising can be challenging due to postal regulations?

Direct mail advertising can be particularly challenging due to postal regulations because it involves sending promotional materials directly to consumers through the mail. This mode of advertising is subject to a variety of rules regarding the types of content allowed, how and where the materials can be sent, and how personal data is handled. Advertisers must ensure compliance with regulations like the CAN-SPAM Act and the Telephone Consumer Protection Act, among others. These regulations often require businesses to obtain consent from recipients before sending marketing materials, provide opt-out options, and adhere to specific formatting guidelines.

Additionally, improper handling of addresses or failure to abide by postal rules can result in delays, returns, or penalties, making it crucial for businesses engaging in direct mail advertising to have a thorough understanding of these regulations to avoid complications.
