Could you build this?
No Building an email delivery API requires extensive MTA infrastructure, IP reputation warming, strict deliverability compliance, and ISP relationship management that cannot be vibe-coded.
What it would actually take: A legitimate transactional email service requires high-throughput SMTP servers (such as Postfix, Haraka, or custom Rust MTAs), automated IP rotation, feedback loop (FBL) processing, DKIM/SPF/DMARC cryptographic signing, and queue workers (Kafka/RabbitMQ). The most difficult challenge is domain/IP warmup algorithms, avoiding global blacklists (Spamhaus, Barracuda), and navigating anti-abuse operations that require dedicated deliverability engineers.
