What Resend does that Ahasend does not
Resend passes llms-full.txt / full agent docs, mcp discoverable, structured api reference, openapi / spec quality, request examples provided, response examples provided, limits / constraints documented, agent-compatible signup flow, programmatic credential creation, official python sdk, mcp integration available, agent compatibility verified, and Ahasend fails them. That is the whole of the gap between the two scores, so if none of those matter to your agent the ranking above overstates the difference.
Why people look for an alternative
