Where each one falls short

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

Courier

Enterprise-only features like RBAC and EU data residency require a custom sales conversation rather than a published plan.
Pay-as-you-go per-send pricing on Business can become costly at very high volume compared to flat committed pricing elsewhere.
The free Developer tier is capped at 10,000 sends per month, which is limiting for growing production apps.

SendGrid

Free plan caps at 100 emails per day and expires after 60 days, per twilio.com/en-us/products/email-api/pricing (Aug 2026), after which sending requires a paid plan
Dedicated IP addresses are only included from the Pro plan at $89.95 per month; Essentials at $19.95 per month lacks a dedicated IP, per Twilio's own pricing page
