Basic plan ($15/mo) includes 10,000 emails then charges $1.80 per 1,000 extra; Pro and Platform tiers have their own lower per-1,000 overage rates ($1.30 and $1.20), so cost scales per email beyond the included volume

All tiers have monthly visitor caps; campaigns exceeding thresholds require upgrading to higher-priced plans
