The short version

  • Only Postmark has a free tier, so it costs nothing to try first.
  • Each has a real cost: ConvertKit the free Newsletter plan allows only one basic visual automation, so sequences beyond a single flow require paying; Postmark free tier caps at 100 emails per month with no overages allowed

Where each one falls short

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

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

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
