Why fashion and streetwear brands need a different email program

Fashion and streetwear sell in drops. Revenue spikes around launches and restocks, so email timing has to follow the hype cycle, not a fixed weekly calendar.

Sizes sell out unevenly. Back-in-stock and waitlist flows often make more than another campaign would.

What email has to do for fashion and streetwear brands

Drop and waitlist flows
Capture interest before a drop and convert it in the first hours.
Restock alerts
Back-in-stock by size, so the customer who missed their size comes back.
VIP early access
Reward repeat buyers with early access instead of discounts.
