In messaging compliance, it's essential to set up a strong defense from the start to avoid filtering by carriers. This involves implementing best practices such as clear consent guidelines, consistent sender identification, and sending relevant content that doesn't fall into unwanted or illegal categories. Consent should be collected clearly, with a record kept of how and when recipients opt-in, and reminders sent monthly for opt-out options. Sender identification is crucial to minimize filtering, and content should be tailored to the recipient's preferences rather than being universally wanted. Additionally, account configurations should utilize subaccounts for different use cases, and proper age-gating should be set up for certain types of content. By following these recommendations, messaging programs can avoid filtering and ensure successful delivery of messages to recipients.
