Why this number isn't obvious
Per-email cost is tiny and batch pricing makes it tinier, so the AI spend is a rounding error against the revenue a saved account represents. The lever is personalization quality per token, not raw price — a slightly better model can lift retention enough to pay for itself many times over.
Frequently asked questions
Can I batch lifecycle emails?+
Yes — they're scheduled, not real-time, so batch pricing applies and roughly halves cost on many providers. Generate the day's cohort in one run.
What data does personalization need?+
Account signals — usage trends, plan, recent activity — passed as input. Keep it to the signals that change the message so input tokens (and cost) stay small.
