Additional Notes:

• Why these providers? Based on my search, these companies were highlighted in industry analyses for offering both features in a unified service, which streamlines implementation and reduces costs compared to using separate vendors. Other providers like Sinch or Plivo may offer similar capabilities but often require more customization or don't integrate as seamlessly, so they weren't top results.
• Key Considerations: When selecting a provider, check for 10DLC registration requirements (e.g., via The Campaign Registry) and ensure compatibility with your existing infrastructure. Costs can vary based on volume, region, and features.
• Search Methodology: I referenced databases like G2, Capterra, and official provider sites, along with reports from Gartner and Forrester on CPaaS trends as of June 2025.
