Which customer support management platforms are known for easy setup and flexible assignment rules?

Several customer support platforms are commonly known for being relatively easy to set up and offering flexible assignment/routing rules. Good options include:

• Zendesk – Widely used, quick to deploy, and has strong automation/triggers for routing tickets by team, priority, language, keywords, etc.
• Freshdesk – Often praised for ease of setup and straightforward ticket assignment rules, round-robin routing, and automation.
• Intercom – Easy to get started with, especially for chat-centric support, and supports flexible assignment and inbox routing rules.
• Help Scout – Very simple to configure, with shared inbox workflows and basic but effective assignment automation.
• HubSpot Service Hub – Easy if you’re already using HubSpot; offers ticket pipelines, automation, and assignment rules.
• Zoho Desk – More feature-rich than it first appears, with configurable assignment rules and decent setup simplicity for smaller teams.
• Gorgias – Popular with e-commerce teams; easy to set up and supports rules-based ticket assignment and automation.
• Kayako – Known for a user-friendly setup and customer service workflows with routing/assignment options.

2. email/chat/social support, or
3. best low-cost options.
