👍 Good boy

👎 Watch out
−Enforces a strict 100 email per day rate limit on the free tier.
−Free event history and log retention expires after 3 days.
−Dedicated IP addresses require upgrading to the Enterprise tier.
−Inbound email parsing is not supported on standard tiers.
The catch
Free tier caps throughput at 100 emails per day and retains logs for 3 days.
