Best For
Best-in-class transactional email deliverability — fast inbox delivery times and transparent uptime reporting
High-volume transactional and marketing email with proven deliverability — the established default
Limitations
No free tier; strictly transactional email only — no marketing or bulk email; fewer SDK languages than SendGrid
UI and developer experience feel dated compared to Resend; owned by Twilio, so pricing and product direction tied to Twilio strategy; support quality inconsistent on lower tiers
