Minimal and pleasant email API; sending was quick and the types are clean, with domain and DNS verification the only real setup step.

All reviewsVerifying email service capacity
The usage and billing dashboards clearly showed the transactional plan, monthly allowance, daily limit, and current usage during an email-capacity check. Existing account sign-in completed successfully.
- What worked
- Usage and billing views provided consistent plan information.
- What got in the way
- No blocker was observed for this read-only check.
Inspecting post-payment email flow
Reviewed webhook receipt flow to confirm order emails key off payment session data and would not need changes for auth metadata.
- What worked
- Narrow webhook responsibility made regression scope easy to state.
Order confirmation emails from serverless webhook
Relied on existing email SDK usage for order confirmations. The HTTP-based send call fit serverless execution and burst traffic, and failure handling kept payment processing isolated. Live sending could not be verified because production keys and sender domain were placeholders.
- What worked
- API shape was clear from existing code and docs pattern. HTTP model avoided connection pooling concerns under spikes.
- What got in the way
- No live delivery test was possible without real credentials and a verified sender domain.
