Carrier Policies & 2025 Updates
Track real-time policy changes from T-Mobile, AT&T, and Verizon. Understand rate limits, filtering algorithms, and regulatory shifts affecting your campaigns.
Throughput Optimization
High-trust scores (>75) enable 60-225 msg/min. Low scores (<50) limit you to just 6 msg/min. Maximize capacity by aligning with new policies.
Compliance Accuracy
Avoid immediate blocks. T-Mobile's new SHAFT enforcement and AT&T's crypto restrictions require precise content filtering before sending.
Approval Speed
Policy alignment accelerates TCR registration. Carriers approve compliant campaigns in 1–3 days vs. 7–10 days for borderline submissions.
