Could you build this?

Partial Creating a wrapper API or MCP server for email is simple, but operating an independent transactional email infrastructure requires complex deliverability systems, reputation monitoring, and abuse management.

What it would actually take: Running a reliable email platform requires managing raw SMTP server clusters (Postfix, Haraka, or custom Rust/Go daemons), automated DNS configuration (DKIM, SPF, DMARC), IP warming algorithms, and dedicated anti-abuse/anti-spam classification pipelines. Otherwise, it simply acts as a thin reseller wrapper over SendGrid/Resend/AWS SES.
