Where each one falls short

Resend

  • Free tier is capped at 100 emails per day, which is restrictive for apps with bursty transactional volume.
  • Marketing and transactional plans are billed and priced separately, so a product needing both must budget for two tiers.
  • Dedicated IPs are only available on the Scale plan and require a minimum daily send volume.

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
