Choose the right messaging service

Developer & Automation

Production APIs for verified individuals using personal applications, household automations and AI agents. All API-originated SMS/MMS is A2P, requires applicable registration and cannot use Consumer/P2P routes.

Personal & Family

Conversational messaging from an authenticated subscriber device. Business, automated, promotional and bulk traffic is not included.

Business

Organizational and application messaging with approved use cases. US local-number business messaging uses the applicable 10DLC Brand and Campaign registration. Toll-free messaging has its own verification requirements.

Communications providers

Messaging services for carriers, resellers and platforms, with traffic review, onboarding and interconnection approval.

From registration to the first message

For US business messaging, register the business identity and campaign or complete toll-free verification, then associate the approved sender with a messaging-capable number. Sender registration, consent and destination rules remain part of the service requirements.

SMS is billed per segment; longer messages can contain multiple segments. MMS is billed per message. Carrier fees and registration charges may apply separately.
