Readers decide in 3 seconds whether your email lives or dies — and the header makes that call. This pack hands you 20 copy-paste AI image prompts across 4 lanes: (1) Newsletter Headers — 5 prompts (minimal brand masthead, magazine-style editorial, illustrated banner art, photo-hero banner, gradient modern pop); (2) E-commerce & Promo — 5 (sale urgency banner, new-arrival showcase, cart-abandon nudge, flash-deal lightning, seasonal collection); (3) Event & Announcement — 5 (webinar invite pro, product launch reveal, holiday greeting, thank-you appreciation, win-back comeback); (4) Niche Brands — 5 (restaurant weekly specials, fitness studio energy, real-estate luxe, SaaS update clean, wedding vendor showcase). Every prompt ships with tool settings for Midjourney, DALL-E, SDXL and Firefly, a negative prompt, a hook caption and a variation — 20 prompts become 40+ headers. Kills the "my emails look amateur" problem: headlines sit in editable blank zones, and every design is built for mobile and dark-mode inboxes. Plus 8 pro tips (contrast, under-200KB exports, alt text) and a 7-day launch plan. Commercial use included.
