Frequently asked questions
Knock and Intercom both help product teams reach users inside the product. Intercom focuses on live chat, a support inbox, and outbound conversational messages. Knock runs those in-app messages on the same platform as lifecycle campaigns and transactional notifications, so marketing, product, and engineering work from one set of audiences, templates, preferences, and delivery logs.
Yes. Knock guides render in your own components, so modals, banners, nudges, inboxes, and toasts match your product. Intercom uses a pre-built messenger, product tours, and a support inbox. The same Knock project also runs lifecycle campaigns: broadcasts to dynamic audiences, multi-step journeys, and a cross-channel follow-up when a user does not engage in the app.
Yes. While getting Knock connected to your messaging providers, data warehouse, and other third-party integrations may require some technical involvement, non-technical users can create messaging workflows, manage notification templates, edit and send one-time messages, ship in-app messaging, and view analytics without developer involvement.
Knock can replace Intercom for outbound lifecycle campaigns, in-app announcements, and product notifications. Teams that need a live support inbox can keep Intercom for conversations. Running both for outbound messaging means duplicate audiences, templates, and preference settings.
Intercom reports conversation volume and outbound engagement. Knock reports opens, clicks, impressions, and dismissals across workflows, broadcasts, and guides, tracks goals with attribution, and streams data to your warehouse. Knock also adds end-to-end delivery observability, so any team can see why a specific message did or didn't reach a user, including the provider's response.
You can. Some teams keep Intercom for live support and move outbound campaigns and product notifications to Knock. Running both for the same messages means duplicate audiences, inconsistent templates, and separate preference settings. Teams that use Intercom mainly for outbound messaging consolidate onto Knock.
Intercom can send transactional messages, and it is built around a support inbox and live chat. Knock applies transactional primitives such as batching, digests, and idempotency across its workflow engine, alongside delivery logs, versioning, and multiple environments.
Knock sends billions of messages in production for companies such as Vercel, Webflow, and Zapier with 99.99% uptime, and handles both scheduled campaigns and real-time, event-driven messages on the same infrastructure.
Intercom supports email, an in-app messenger, push, and SMS. Knock supports email, SMS, push, and in-app, plus native Slack, Microsoft Teams, and WhatsApp, and webhooks for custom channels. You can connect 25+ providers, for example Amazon SES for email or Twilio for SMS in 180+ countries, and switch providers without rebuilding campaigns.
Knock has transparent usage-based pricing that starts at $0 for the first 10,000 messages, with volume discounts for larger companies. All plans include unlimited data ingestion and unlimited channels with no onboarding or service fees; you pay for messages sent. Intercom prices by seats and plan.
Knock holds SOC 2 Type 2 certification and supports GDPR and CCPA requirements on every plan.
Most teams migrate in 2 to 4 weeks, depending on how many in-app experiences and workflows they run. Knock's support team helps with the move.
