Where each one falls short

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

Donorbox

  • Standard plan charges 2.95-3.95% platform fee per donation on top of payment processor fees (2.2-2.49% + card processing)
  • Premium plan pricing requires contacting sales, not displayed publicly
  • Pro plan limited to growing organisations; larger nonprofits must upgrade to Premium with custom pricing

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
