Summary
SMS error 30007, indicating a carrier violation or spam block, arises from several interconnected issues: non-compliance with carrier guidelines and TCPA regulations, problematic message content (spam-like text, excessive use of caps/special characters, short codes), use of shortened or shared links impacting link reputation, and inadequate opt-in processes with missing opt-out options. Addressing these factors requires reviewing and revising message content, using branded short links, adhering to TCPA guidelines by gaining documented consent (potentially double opt-in), and continuously monitoring deliverability to maintain compliance and avoid recurrence.
