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

Zonka Feedback

  • No pricing tier is published for either the core product or the AI add-on, so total cost is unknown until a sales quote is obtained.
  • The AI Feedback Intelligence product is priced separately on data credits, meaning a buyer who wants both feedback collection and AI analysis is negotiating two line items, not one.
  • Third-party pricing estimates in the low hundreds to near a thousand dollars a month vary enough that budgeting from public sources alone is unreliable.
  • Kiosk hardware and offline capture are a strength for physical locations but add limited value to a purely digital-only business, which pays for a capability it does not use.
  • It is a smaller vendor than Medallia or Qualtrics, so enterprise buyers evaluating analyst-recognised platforms may not shortlist it despite comparable core features.
