Which is a weakness of all promotional messages, regardless of their delivery method?

A weakness of all promotional messages, regardless of their delivery method, is the potential for being perceived as biased or lacking in objectivity. Promotional messages are designed to promote a specific product, service, or brand, often using persuasive tactics to influence consumer behavior. This inherent bias can make customers skeptical and less likely to trust the message, as they may perceive it as a sales pitch rather than an unbiased source of information.
