Solicited proposals and offers are generally more effective for several reasons:
Relevance: Since the request was made by the recipient, the proposal is more likely to be relevant to their needs. Higher Success Rate: The likelihood of acceptance is higher as the recipient is already interested. Better Engagement: Recipients are more engaged and responsive to solicited offers, which can lead to more productive business relationships. Professionalism: Solicited proposals are often seen as more professional and respectful, enhancing the sender's brand reputation.
