Tickets, conversations, customers, and articles can usually be exported via each vendor's API. Intercom → Zendesk: use Zendesk's import API or a third-party like SkyvIA/Help Desk Migration. Zendesk → Intercom: similar. Workflows don't port — rebuild triggers/macros. Budget 2-4 weeks for a real migration with content + training + integrations.

Yes. Both have MCP servers installable via MCPizy (mcpizy install intercom and mcpizy install zendesk). They work identically across Claude Code, Claude Desktop, Cursor, Windsurf, and any other MCP-compatible client. You can install both side by side and route queries in your agent's prompt.
Resend is the new developer-first transactional email API — React Email templates, great DX, simple pricing. SendGrid (Twilio) is the incumbent with enterprise features, marketing tools, and massive scale. For modern transactional use-cases, Resend usually wins; for high-volume marketing + enterprise, SendGrid.
Both are developer-first transactional email providers with strong reputations. Postmark has been the deliverability king for years (separate transactional + broadcast streams, obsessive focus). Resend is newer, has React Email templates, and simpler pricing. Both are excellent — pick on DX fit.
Twilio is the market leader in CPaaS — SMS, voice, WhatsApp, Verify, Studio flows, Segment (CDP). Vonage is the #2 with often cheaper international SMS rates and strong voice quality. For US/EU volumes and ecosystem breadth, Twilio. For cost-sensitive international SMS, Vonage often wins.
