Microsoft Copilot now writes full marketing campaigns from a single product brief

End-to-end campaign generation — ad copy, email sequences, landing pages, social posts — from one prompt. In internal tests, Copilot-generated campaigns matched human-created ones on conversion metrics while taking 95% less time. Agencies scramble to redefine value beyond execution.

Why it matters: The campaign creation bottleneck just disappeared. Speed-to-market becomes the only moat.
