/sales-newsletter — Newsletter monetization strategy (paid subscriptions, sponsorships, ad sales, pricing)/sales-sponsorgap — SponsorGap sponsor intelligence (38K+ brands, verified contacts, competitor monitoring, spend trends, API)/sales-sponsorleads — SponsorLeads sponsor lead lists (4,318+ companies, decision-maker contacts, Airtable database)/sales-paved — Paved newsletter sponsorship marketplace, Ad Network, Booker, Radar/sales-reletter — Reletter newsletter search engine (7M+ publications, subscriber data, creator contacts, API)/sales-sponsy — Sponsy sponsorship operations (ad inventory calendar, sponsor CRM, customer portals, reporting)/sales-ohmynewst — OhMyNewst newsletter sponsorship marketplace for Spain & LATAM/sales-do — Not sure which skill to use? The router matches any sales objective to the right skill. Install: npx skills add sales-skills/sales --skill sales-doUser says: "I run a developer tools newsletter with 15,000 subscribers. How do I use Who Sponsors Stuff to find sponsors?" Skill does: Explains filtering by tech/developer vertical, how to use ad creative screenshots to understand what sponsors expect, suggests CSV export workflow into outreach tool, recommends daily alerts for new tech sponsors Result: User has a targeted sponsor prospecting workflow with visual competitive intelligence
User says: "Should I use Who Sponsors Stuff or SponsorGap for finding newsletter sponsors?" Skill does: Compares data coverage (WSS 8K+ sponsors with ad creative vs SponsorGap 38K+ brands with API), pricing transparency (WSS requires contact vs SponsorGap $39-$199/mo), differentiators (WSS has ad screenshots, SponsorGap has competitor monitoring and API) Result: User picks the right tool — WSS for visual competitive intel, SponsorGap for programmatic workflows
User says: "How do I automate getting notified when new sponsors start advertising in fintech newsletters?" Skill does: Walks through setting up custom email alerts by vertical, explains ~20 new sponsors/day cadence, suggests combining with CSV export workflow to maintain a running prospect list, notes no API/webhook workaround Result: User has a daily alert → CSV export → outreach pipeline despite no API
Symptom: Searching the free database returns few or no relevant sponsors Cause: The free tier only exposes ~10% of the full database — your niche may not be in the free subset Solution: The weekly Email Intelligence newsletter (free) surfaces 10 new sponsors/week across all verticals. Subscribe to gauge sponsor quality before upgrading to Sales Pro.
Symptom: No public pricing page, unsure what it costs Cause: Who Sponsors Stuff uses a contact-based sales process for Sales Pro Solution: Email [email protected] or use the "Get in Touch" form. For budgeting, comparable tools range from $39-$200/mo. If price sensitivity is a concern, start with SponsorGap Starter ($39/mo) or SponsorLeads ($97/mo) which have transparent pricing.
Symptom: Outreach emails to exported contacts bounce or go unanswered Cause: Decision-makers change roles; contact data has a shelf life Solution: Verify emails with a tool like ZeroBounce before loading into your outreach tool. Cross-reference contacts with LinkedIn. Focus on sponsors who entered the database recently (use date filters or recent alerts).
