Editorial take
Why it stands out
Start by matching daily cap (free) vs monthly bundles (paid)—the free tier is 100/day, not 10k/mo. Foundation vs Scale is about SSO, validations, IP pools, and log retention, not just message count. Overage ladders change by tier—import the live table into finance models. For alternatives, SendGrid adds marketing UI; Postmark simplifies transactional; SES minimizes transport cost.
