Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
smsmode RCS API provides RCS Business Messaging through a REST API, with web and API access for businesses that need interactive customer conversations. Its message formats include rich cards, images, maps, action buttons and carousels, while conversational sessions support two-way messaging. The platform also covers RCS agent registration and validation, branding, verified sender identity, delivery measurement, read measurement and click measurement. SMS fallback supports delivery to incompatible devices, and API-key authentication is available for access control.
Pricing combines monthly subscriptions with consumption-based messaging charges. The Basic plan costs €9 per month and includes email customer support five days a week. Classic costs €69 per month and adds RCS BASIC, RCS SINGLE and RCS MT Session as usage channels, plus email and telephone support five days a week. Medium costs €159 per month and adds a dedicated account manager. Premium costs €499 per month and includes the same usage channels, a dedicated account manager and 24/7 customer support on all channels. The published tiers give teams a clear subscription structure, while messaging spend depends on consumption and RCS is not offered as a prepaid service.
Its ecosystem fit is practical for teams connecting RCS to existing marketing, sales and automation workflows. Integrations include HubSpot, Salesforce, Klaviyo, Adobe Campaign, Zapier and Customer.io. Businesses can use the API, interface or agency service, depending on how they want to operate RCS messaging. Agent validation must be completed before sending, so teams should account for that onboarding step. smsmode RCS API suits organizations seeking rich, measurable messaging with fallback and established integrations; teams wanting prepaid RCS or a simpler channel without validation requirements should choose an alternative.
