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
Runway
- The free tier is 125 one-time credits rather than a monthly allowance, so it runs out and does not refill
- Outputs carry a watermark until the Standard plan at $12 a month
- Everything is metered in credits, and Gen-4.5 video costs 60 credits per 5 seconds, so a Standard plan covers roughly 125 short videos a year
- Only the Max plan at $76 a month rolls unused credits over, and only for one month
- The free tier gives a selection of models rather than the full set
