Best For
Email API with strong inbound email parsing — useful for agents that need to receive and process emails, not just send
Modern developer experience for transactional email — clean API, React Email support, great docs
Limitations
Free tier is limited to a trial period; UI is less polished than competitors; owned by Sinch, product direction less predictable
Newer platform with smaller track record; no marketing email features; deliverability reputation still building compared to SendGrid
