Here are the top Intercom alternatives for omnichannel communication management, with a short summary of what each is best at and a link to a vendor/source for details. Pick by the channels you need (chat, email, SMS/WhatsApp, voice), whether you need heavy customization/API access or an out‑of‑the‑box inbox, AI capabilities, and your team size/budget.

Brief buying checklist (what matters most)

• Channels: confirm required channels (WhatsApp/Instagram/voice/SMS/social). Some vendors include all; others need add‑ons or API work (Twilio/MessageBird are strong for telco channels). (twilio.com)
• Scale & customization: enterprise contact centers usually use Twilio Flex, Zendesk, Genesys or LivePerson; SMBs often prefer Freshdesk, Front, Help Scout. (twilio.com)
• AI & automation: compare built‑in AI (Freddy, Zendesk Copilot, LivePerson/Gladly AI) vs. “bring your own LLM” or custom bots. (freshworks.com)
• Integrations & CRM: if you need tight CRM/Sales alignment, favor HubSpot, Zendesk (with CRM connectors), or build on Twilio’s APIs. (knowledge.hubspot.com)
• Implementation cost: vendor pricing models vary (per‑agent monthly, per‑hour, or consumption). Platforms like Twilio Flex are flexible but require dev work; SaaS suites are faster to deploy. (twilio.com)
