Mailmodo Rate Limits

Mailmodo publishes per-second API request ceilings, but only on its PRICING page as a plan feature ("5 / 10 / 50 API Request / Sec") — never in the API documentation and never as a response header. Re-read from the live pricing page on 2026-08-13. The runtime side of rate limiting is entirely undocumented: no X-RateLimit-* headers, no RateLimit-* headers, no Retry-After, and no declared status code on exhaustion in any of the eight provider-published OpenAPI documents. An agent therefore has no way to detect that it is approaching a limit — it can only pace itself against the number printed on the pricing page.
