Brew Resale Margin Ladder

Brew's published plans set a hard cost floor that agencies must price above: Free at $0 with 500 AI credits and 1K sends, Growth at $99 with 10K credits and 50K sends, Pro at $249 with 25K credits and 200K sends. The margin ladder maps each plan to a client retainer band. A single client on Growth at $99/month supports a $49-$249/month retainer only if that client stays under the 50K send ceiling; stack three to five low-volume e-commerce brands on one Growth workspace (10 brand workspaces included) and the per-client cost drops below $25, which is where the retainer margin actually lives. The Pro plan's 50 brand workspaces matter for agencies running 20 or more accounts. Watch the AI credit ceiling: heavy prompt-driven campaign generation burns credits faster than sends, so a client requesting weekly campaign refreshes can exhaust 10K credits before the send limit is reached. Price the retainer against credits, not list volume.
