Why Marketing Token Costs Matter

AI marketing content has a different token profile than simple Q&A or support. Every marketing piece includes:

A typical marketing piece uses ~2,000 input tokens and ~800 output tokens. That's 3x the input of a simple email but only 2.5x the output. The cost difference at scale is significant: DeepSeek V4 Flash costs $151/month while Claude Sonnet 4.6 costs $540/month for 100 pieces per day.

The key cost insight: marketing content quality directly impacts revenue. A 1% improvement in ad click-through rate or blog engagement is worth far more than the model cost difference. Use premium models for high-visibility content (landing pages, pillar blog posts, hero ad copy). Use budget models for high-volume variants (A/B test copies, social media drafts, product descriptions).
