  • Pricing based on audio hours consumed
  • Not a full podcast hosting solution

ConvertKit

  • The free Newsletter plan allows only one basic visual automation, so sequences beyond a single flow require paying
  • The free plan is a single user, and the Creator plan at $33 a month allows two
  • Subscriber signals, engagement analytics and paid recommendations are Pro only, at $66 a month
  • A/B testing is capped at 2 subject lines below Pro, which allows 5
  • Paid pricing is banded by subscriber count, so the published figures apply only at the smallest band
