The fastest way to research email marketing.

Why we built it

Great email marketing is hiding in plain sight. It lands in millions of inboxes every day — and then disappears. There was no Figma for email, no Are.na for subject lines, no easy way to ask "what is Nike sending right now?" without joining their list. So we built the library we wished already existed: every send from every brand we could find, searchable and sortable, with the full HTML preserved exactly as subscribers saw it.

Who it's for

Campaign Buzz is for anyone whose work touches email — and anyone curious about how the best brands talk to their customers. That includes:

• Marketers and lifecycle teams studying what works, benchmarking competitors, and pulling references for the next launch.
• Designers looking for layout patterns, type treatments, and hero ideas grounded in real campaigns instead of dribbble fantasy.
• Copywriters and editors studying subject lines, voice, and how brands sequence a message.
• Founders and solo operators who need to write their first welcome email tonight and want to see how companies they admire did it.
• Agencies and consultants pulling references for pitches, audits, and client reviews.
• Researchers, analysts, and trend trackers watching how categories evolve — pricing language, holiday cadence, AI announcements, the long tail of design trends.
• Brand and competitive intelligence teams keeping an eye on what rivals are shipping without signing up for every list on the internet.
• Journalists, writers, and educators who need primary sources when covering brands, campaigns, or the craft of marketing itself.
• Students and the merely curious — because great work is worth studying, no matter your job title.

What you can do with it

Search millions of emails by brand, subject line, or keyword. Browse a brand's full sending history end to end. Spot trends across categories and seasons. Save references for the next launch, newsletter, or lifecycle flow. Track competitors without ever joining their list. The library is free to browse, and the deeper research tools are there when you need them.

Who uses it today

Teams at OneSignal, ByteDance, Samsung, NYU, and thousands of other companies, agencies, and independent creators use Campaign Buzz every week. Some come for a single reference. Some come every morning. Either way, we built it for you.
