Real newsletters over mock-ups or screenshots
We could have shown cropped screenshots of the ad sections, or recreated the ads in a standardized template. Both would be easier to maintain and more visually consistent. But they strip away the context that actually matters to advertisers.
Rendering the full newsletter HTML in an iframe preserves everything — the creator's design, the surrounding editorial content, the reading experience. An advertiser can scroll through the newsletter exactly as a subscriber would. This is the strongest trust signal: not "here's what your ad could look like" but "here's what an ad actually looked like, in a real newsletter, sent to real subscribers."
Sales calls Q1 2026 — prospects repeatedly asked "can I see what it looks like?"
Category-first organization over chronological
The most natural default for a directory is chronological — newest first. But advertisers don't care when an ad ran. They care whether newsletters in their vertical carry ads like theirs.
Organizing by advertiser category (Productivity, Privacy, Health, etc.) lets an advertiser in the productivity space immediately find relevant examples without scrolling past unrelated verticals. The category filter is the primary navigation, with chronological as a secondary sort within each category. The initial four categories — Productivity, News & Media, Privacy & Security, Health & Wellness — reflect the verticals where the majority of current Kit Ads bookings concentrate. The taxonomy should expand as the advertiser mix broadens.

Subscriber counts shown on every card
Including audience size on every card is a deliberate choice. Advertisers evaluate newsletter ads on two axes: creative quality (does it look good?) and audience scale (will it reach enough people?). Hiding subscriber counts behind a click would add friction to the most common evaluation pattern.
Showing real subscriber numbers also reinforces credibility — these aren't hypothetical placements, they're real newsletters with real audiences. The numbers range from 89K to 145K in this prototype, reflecting the actual Kit Ads network scale.

Shareable as a standalone link, not gated behind login
This directory needs to work as a sales tool that can be dropped into an email or Slack message. If it requires a Kit account or login, the sales team can't share it with prospects who haven't signed up yet — which is the entire target audience.
The prototype is a static site served from a public URL. No authentication, no account required. The tradeoffs go beyond competitors viewing it: creators whose newsletters appear here should consent to being featured, and subscriber counts on a public page need a refresh mechanism so stale numbers don't misrepresent audience size. An advertiser might also assume every listed newsletter is currently accepting ads. These are real risks worth solving in production — but for validating the core concept with the sales team, an ungated prototype is the right starting point.
