Where each one falls short

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

AdBlock Plus

  • Acceptable Ads allowlist model generates controversy over ad filtering conflicts of interest
  • Smaller feature set compared to open-source alternatives like uBlock Origin
  • Less customization and dynamic filtering compared to uBlock Origin
  • Mobile version less comprehensive than desktop extension
  • Chrome version increasingly limited due to Manifest V3 migration

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
