Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
Castos
- Transcripts are metered by tier, at 10 a month on Essentials and 100 on Pro
- Private podcast subscribers are capped, at 100 on Essentials and 500 on Pro
- Video hosting and the uptime SLA require the Pro tier at $99 a month
- SSO and a dedicated account manager are Premium only, from $499 a month
- Team seats are limited by tier, at 5 on Growth and 10 on Pro
Mailchimp
- The free plan allows 250 contacts and 500 sends a month, with a 250 daily cap
- Price is driven by contact count, so the list growing raises the bill regardless of how much you send
- Send allowances are a multiple of contacts, 10x on Essentials and 12x on Standard, so a large list with heavy sending forces a tier change
- Essentials allows 3 seats and Standard 5; unlimited seats need Premium at $350 a month
- The headline $13 and $20 prices are for 500 contacts, not a flat rate
