Free Tier Value
This free sandbox is a real but tightly capped starter tier: it includes one inbox, 50 messages a month, signed webhooks, and basic retention, but it is limited to a small build-and-test workload. Compared with the cheapest paid plan at $9/month, it feels worth about $2/month - roughly 20-25% of Pro’s practical value - and the 14-day trial on paid plans adds some extra runway, but the free offer itself remains perpetual and capped.
