Strengths and weaknesses
- +Transactional email is free and unlimited on any paid plan (previously ~$1 per 2,000 sends), so transactional volume never inflates the bill
- +Unified platform: marketing, product/lifecycle, triggered sequences, and transactional share one domain and one sender reputation, removing the need for a separate SendGrid/Mailgun
- +Modern developer experience: clean TypeScript/Node SDK, idempotency-key support, MJML template uploads, and well-regarded docs
- –Contact-based pricing penalizes large or dormant lists you pay per stored contact regardless of whether you email them
- –Transactional is treated as part of the broader workflow system, not a dedicated hardened delivery API less granular control than Postmark/Resend/SendGrid
- –Data variables limited to strings and numbers; no raw-HTML-at-send model (templates must live in Loops)
- +First-class React Email integration, compose emails as React components that render across major clients
- +Excellent developer experience: clean REST API, fast setup (often ~30 min including DNS), clear docs and useful per-message logs
- +Generous free tier (3,000 emails/month) and simple, transparent volume-based pricing
- –Intermittent email-sending latency, recurring reports and published incidents of delayed delivery, sometimes minutes or more
- –Less mature deliverability tooling and guidance than incumbents like Postmark, especially as volume scales
- –Analytics are thinner than legacy platforms; users want deeper reporting and proactive DNS/reputation warnings
