Subject Line: Puppies!!!
J. Crew hit it out of the park with this subject line. Who could possibly resist Puppies!!!?
On another note, the J. Crew email creative team is doing nice work with their mobile optimized emails. This one renders prettily whether viewed on desktop, mobile or tablet, and features bold and brief headlines, short and sweet copy, and easily clickable CTAs (call-to-action).
