Transactional email your AI-built app already owes users from day one
Your AI-built app has working signup, working sign-in, and working password reset. You tested all three yourself and watched each one succeed. What you never saw is the email each flow sends, because you were looking at the app while the most trust-sensitive part of the experience landed in an inbox you never opened.
Transactional email is the surface builders forget. These are the messages your app sends because something happened: confirm your address, reset your password, here is your receipt, your sign-in method changed. Users judge your app by these emails far out of proportion to the effort they take. A polished app that sends a raw default password-reset email from an unfamiliar sender reads as a side project.
