The short version

  • Each has a real cost: Quo unlimited calling to US and Canadian numbers is subject to a Fair Usage Policy rather than being truly unlimited; 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
