Smooch (Sunshine Conversations) and Zendesk compete in the same category but tune their feature sets for different team profiles. The material differences cluster around channel coverage, automation depth, reporting, and team management. The side-by-side below draws on aggregated G2 and Capterra reviews. A flat-rate alternative like Converge ($49/month for up to 15 agents) may sidestep the trade-off entirely.
Sunshine Conversations is the messaging layer inside Zendesk — the comparison is between the API component and the full platform it belongs to. Sunshine Conversations API provides: multi-channel messaging (WhatsApp, Messenger, Instagram, LINE, Viber, custom), conversation orchestration, switchboard for routing between bots and humans, user identity linking across channels, and structured message types (carousels, quick replies, forms).
Zendesk Suite wraps this API with: a ticketing system, agent workspace, Guide knowledge base, Talk voice, Explore analytics, AI Copilot ($50/agent), and the 1,500+ app marketplace. Most businesses use Zendesk Suite and get Sunshine Conversations implicitly — the API powers the messaging behind the scenes.
The standalone API use case is narrow: large enterprises building custom conversational experiences, chatbot platforms routing to human agents, or developers connecting Zendesk messaging infrastructure to non-Zendesk agent tools. For standard support operations, the Suite is the product.
How much do Smooch (Sunshine Conversations) and Zendesk cost?
Smooch (Sunshine Conversations) starts at From $55/seat/mo (per seat); Zendesk starts at From $55/seat/mo (per seat). Converge is $49/month flat for up to 15 agents with all channels and AI included.
Zendesk Suite Professional at $115/agent/month includes Sunshine Conversations features. Standalone Sunshine Conversations API adds $0.10-$0.15 per MAU on top of base Zendesk licensing. For most businesses, the messaging capabilities come bundled — there is no separate "Smooch" cost. You pay for the Zendesk Suite tier you need.
Suite tiers: Team $55/agent, Growth $89/agent, Professional $115/agent, Enterprise $169/agent (all annual). Sunshine Conversations features (switchboard, multi-channel orchestration) are fully available on Professional and above. Basic messaging works on all tiers.
Standalone API pricing: per-MAU model favors low-volume use cases. High-volume messaging (100K+ MAU) requires enterprise pricing discussion. Implementation requires developer resources — the API is not a no-code product.
