Strengths and weaknesses
- +Deepest and best-organized developer documentation in the CPaaS category, with quickstarts in every supported language
- +Truly global carrier reach with high deliverability across regions, handling high volume without delivery issues
- +Official, actively maintained helper libraries in seven languages plus TwiML for server-side logic
- –Effective per-message cost runs 40–60% above the headline rate once US carrier pass-through fees are added
- –Unpredictable monthly bills at scale from layered A2P 10DLC brand/campaign fees, failed-message charges, and add-ons
- –Support is frequently described as slow to respond, especially for smaller accounts without enterprise plans
- +Pure pay-as-you-go with no platform fee or monthly minimum, easy, low-commitment entry
- +Multichannel Messages API unifies SMS, MMS, RCS, WhatsApp, Messenger, Viber, and email behind one JWT-authenticated interface
- +Six official server SDKs (Node, Python, PHP, Java, Ruby, .NET) plus broad, well-regarded documentation
- –Dashboard/console is clunky and click-heavy for managing many numbers or auditing logs
- –24/7 premium support is a paid add-on (~$3,300/mo); lower tiers report slow, chat-routed support
- –Reviewers cite fraud-detection and account-security gaps that have caused downtime
