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

Triple Whale

  • Shopify-first focus limits functionality for multi-platform ecommerce operations beyond Shopify ecosystem
  • Creative analytics and advanced features sold as add-ons beyond base plan pricing
  • GMV-based pricing for larger brands creates unpredictable costs at scale
