    Example session with this skill installed

    Considering whether to build our own email delivery system or use SendGrid. We're a 4-person SaaS startup, sending about 50k transactional emails/month. Engineering rate ~$120/hr. Our product has nothing special about email — it just needs to get sent.

    Criterion Weight Score Weighted Rationale
    Core Competency 20% 1 0.20 Email delivery is not the product; it's infrastructure
    Strategic Differentiation 20% 1 0.20 No competitive edge from custom SMTP handling
    Total Cost of Ownership 15% 2 0.30 Build requires DKIM/SPF, bounce handling, IP warmup — months of work
    Time to Market 15% 1 0.15 SendGrid API is 1 day to integrate; building is 6–8 weeks minimum
    Integration Complexity 10% 1 0.10 REST API, SDK available, drop-in for all major languages
    Vendor Lock-in Risk 10% 2 0.20 Email APIs are commodity; switching to Postmark/SES takes < 1 week
    Team Capability 5% 2 0.10 Team could build it, but it's not a good use of 4 engineers
    Long-term Maintenance 5% 1 0.05 Team wants zero maintenance on deliverability infrastructure
