Why Postmark scores 96%

Budget fit (weight 30, our estimate) — Runs free at your usage — $0 vs your $50/mo budget+30

Batteries included (weight 12, our estimate) — Bundles template tooling, inbound parsing — fewer services to glue at team size 1+8

Exit cost (weight 4, our estimate) — Standard SMTP + API — switching providers is a config change plus warmup+3.2

Ecosystem maturity (weight 8, our estimate) — established — our estimate from ecosystem age, docs and hiring pool+8

Free-tier runway (weight 10, our estimate) — Your usage fits the free tier today (100 emails/month, full features)+10

Total (lines sum exactly)59.2

Possible range −64…+64 (sum of active rule weights) · fit % = (total + max) / (2 × max)(59.2 + 64) / 128 = 96%
