Public capabilities
Chert describes a REST API and webhooks, typing, reactions, delivery status, media and multi-recipient threads. SMS or RCS fallback is also promoted. These capabilities make it relevant to an agent application that needs more than a simple outbound text endpoint.
Commercial questions first
The reviewed homepage does not establish a numeric production rate. Request a quote and a written description of daily limits, number allocation and the relationship between an application user and a sending identity. Those decisions affect whether a returning user recognizes the same conversation.
A concrete evaluation
Use a pilot to inspect participant identifiers, channel reporting and a human joining the thread. Ask what happens to queued work during a line restriction or replacement. Do not infer that rich demonstrations establish guaranteed delivery or a particular response-rate improvement. We have read the public product description, not audited Chert’s infrastructure.
