Resend vs Postmark for Claude Code
Verdict
Resend has the stronger Claude Code integration today: Resend (5/5: official Anthropic-marketplace plugin with MCP server + 5 skills), versus Postmark (3/5: official MCP server (24 tools) but no Claude Code plugin or skills found). That doesn’t make it the better product for every team, but your agent will get more official tooling out of the box.
