Documented steps Default limit: 10 requests/second per TEAM (shared across all the team's API keys) — throttle client-side accordingly Watch response headers ratelimit-limit, ratelimit-remaining, ratelimit-reset on every call On 429, honor the retry-after header (seconds) before retrying; use a queue for burst sending Track plan quotas via email response headers x-resend-daily-quota (free plan) and x-resend-monthly-quota For sustained higher throughput, request a rate limit increase from Resend (granted for trusted senders) Known gotchas 429 is used for BOTH rate limiting and quota exhaustion (daily_quota_exceeded / monthly_quota_exceeded) — inspect the error body Both sent and received emails count toward quotas The limit is per team, not per API key — parallel workers with separate keys still share the same 10 req/s budget Docs: https://resend.com/docs/api-reference/rate-limit
