Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Postmark

  • Free tier caps at 100 emails per month with no overages allowed
  • 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
  • Custom high-volume pricing above the published tiers requires contacting sales

Transistor

  • Starter plan at $19 per month caps monthly downloads at 20,000
  • Private podcast subscribers are capped at 50 on Starter and 500 on Professional
  • Dynamic ad insertion and auto-posting to YouTube require the $49 per month Professional plan or higher
  • Removing Transistor branding requires the $99 per month Business plan
  • Enterprise plans above 250,000 monthly downloads start at $199 per month and require contacting the vendor
