Zendesk is the enterprise standard for customer support with ticketing, live chat, knowledge base, and AI-powered automations. Reliable but increasingly expensive and complex.
Reviewer scorecard
“One API for all notification channels. The workflow builder handles complex routing and preferences elegantly.”
“Robust API and marketplace. Building custom apps and integrations is well-supported. Webhooks and triggers are powerful.”
“Building notification infrastructure from scratch is surprisingly complex. Knock handles preferences, batching, and multi-channel delivery.”
“Bloated, expensive, and the UI hasn't meaningfully improved in years. Intercom and Freshdesk offer better value.”
“Notification infrastructure as a service will become standard. Every app needs it, nobody wants to build it.”
“The help center themes are limited and customization requires coding. Not the most design-friendly support platform.”
