Resources for enterprise messaging teams
Practical guides and reference material, written to be clear and to the point.
About these resources
Written for the people who buy and run messaging
These guides explain the topics enterprise teams ask us about most: what A2P messaging is, when to use SMS, RCS or WhatsApp, how sender names are registered, how compliance works in general and what to ask a provider before signing. They are general explanations. Where a topic depends on country, operator or contract, the guide says so and points to the right next step.
Technical readers can go straight to the API documentation or the SMS API overview. Procurement and security teams will find the pricing model, security information and terms linked in the reference section below.
