Auth email template friction — local-state visual builder with safe blocks

Auth email template friction — local-state visual builder with safe blocks targets a $4.8B = 800,000 developer-led SaaS & mid-market companies x $6K ACV (annual tools/add-ons for transactional-auth email workflows) total addressable market with medium saturation and a year-over-year growth rate of 15% (developer tooling + transactional email tooling growth driven by SaaS expansion).

Key trends driving demand: API-first identity & transactional email -- more platforms expose programmable hooks, making plug-in UX tools possible and valuable; Developer self-serve expectations -- teams prefer embedable, low-friction tools that avoid platform/API changes; AI-assisted content & localization -- automatically generated subject lines, copy variants and A/B suggestions reduce time-to-first-send; Focus on security & compliance -- more teams want safe editing surfaces that minimize injection/XSS and preserve deliverability practices.
