Also known as: Viral Marketing · Viral Advertising · Viral Email · Pass-Along Email
Viral marketing email is the practice of crafting promotional content that spreads organically through forwarding, social sharing, and word of mouth online1. The concept dates back to the mid-1990s, when services like Hotmail turned every outgoing message into a tiny advertisement, and it evolved through landmark campaigns like Burger King's Subservient Chicken and Old Spice's real-time YouTube responses3. As a category of internet culture, viral marketing sits at the intersection of advertising and meme creation, with the most successful campaigns becoming shared cultural moments in their own right.
Overview
Viral marketing email describes any promotional message or campaign engineered to propagate from person to person without traditional ad spending driving each impression. The term covers everything from forwarded email promotions to elaborate branded video campaigns designed for social sharing3. A viral email spreads when someone receives a message, usually humorous or provocative, and forwards it to contacts who do the same, creating an exponential distribution chain similar to biological contagion1.
What separates viral marketing from spam is the social layer. Spam blasts unsolicited messages to massive lists. Viral campaigns rely on recipients choosing to pass the content along because it's funny, surprising, or useful enough to share1. The best examples blur the line between advertisement and entertainment so thoroughly that people share them the way they'd share a meme.

How to Use This Meme
Viral marketing email isn't a meme template in the traditional sense but rather a strategy category. In practice, brands typically follow a few patterns:
The embedded hook — Include a shareable element (tagline, link, voucher) inside every email or message that gives recipients a reason to forward it. Hotmail's footer tagline is the original version of this approach3.
The entertaining bait — Create content so funny, shocking, or compelling that people share it voluntarily. "Will It Blend?" and Old Spice response videos both used entertainment value to earn organic distribution3.
The social challenge — Invite users to participate and create content themselves, as Doritos did with "Crash the Super Bowl"3.
The voucher chain — Send discount codes or offers designed for forwarding. UK off-licence chain Threshers emailed vouchers to staff and suppliers in 2006. Recipients forwarded them so aggressively that multiple branches nearly ran out of stock1.
