If the question is Megahit-specific, continue to Step 3.
Step 3 — Megahit platform reference
Read references/platform-guide.md for the full platform reference — capabilities, enrichment workflow, ESP integrations, comparison with alternatives.
Answer the user's question using only the relevant section. Don't dump the full reference.
Step 4 — Actionable guidance
Focus on the user's specific situation:
Getting started: Connect your ESP, run an enrichment on your existing list, then filter by job title or company to find marketing decision-makers who could become sponsors. The "inside-out" approach (finding sponsors in your own audience) yields higher reply rates than cold outreach because these people already read your newsletter.
Building a sponsor pitch list: After enrichment, filter for titles like "Head of Marketing," "Growth Lead," "CMO," "Founder" at companies that advertise in newsletters. Cross-reference with SponsorGap or Who Sponsors Stuff to confirm active sponsor budgets.
Choosing Megahit vs alternatives: Megahit finds sponsors within your existing audience (inside-out). SponsorGap, Who Sponsors Stuff, and Open Rates find sponsors outside your audience (outside-in). Both approaches complement each other — use Megahit first (warm leads), then outside-in tools for cold outreach.
If you discover a gotcha, workaround, or tip not covered in references/learnings.md, append it there.
Gotchas
Best-effort from research — review these, especially items about pricing and integration details that may change.
$600 one-time fee with no free trial: No way to test before buying. Ask for a demo to see enrichment quality on a sample of your list before committing.
No API, no webhooks, no Zapier/Make/MCP: All operations are through the web interface only. No programmatic access to enriched data.
Privacy-first but requires your subscriber list: Megahit runs on customer-controlled servers and claims never to share email lists. Verify their privacy policy and data processing agreement before uploading subscriber data.
Enrichment quality depends on email types: LinkedIn data enrichment works best on work emails. Gmail/Yahoo subscribers will have lower match rates.
Limited ESP integrations: Supports Beehiiv, Kit, Campaign Monitor, EmailOctopus, Ghost, HubSpot, Mailchimp, SendGrid, and Substack. If your ESP isn't listed, you may need to export/import CSV manually.
Solo founder product: Built and maintained by a single developer (Niklas Wenzel). Consider the bus-factor risk for a $600 investment.

Examples
Example 1: Finding sponsors in your subscriber list
User says: "I have a 12,000-subscriber B2B marketing newsletter on Beehiiv. How do I find potential sponsors among my subscribers?"
Skill does: Walks through connecting Beehiiv to Megahit, running enrichment, filtering for marketing decision-makers at companies with ad budgets, building a prioritized outreach list
Result: User has a targeted list of warm sponsor leads who already read their newsletter
Example 2: Comparing Megahit to sponsor intelligence tools
User says: "Should I use Megahit or SponsorGap to find newsletter sponsors?"
Skill does: Explains the key difference — Megahit finds sponsors inside your audience (warm leads, higher reply rates) while SponsorGap finds sponsors outside your audience (larger database, verified contacts, API). Recommends using both: Megahit first for warm outreach, then SponsorGap for cold prospecting.
Result: User understands the complementary approaches and picks the right tool for their stage
Example 3: Enrichment quality concerns
User says: "Will Megahit work if most of my subscribers use Gmail addresses?"
Skill does: Explains LinkedIn enrichment match rates, notes that work emails yield better results, suggests strategies to improve enrichment coverage (ask subscribers for work email at signup, use progressive profiling)
Result: User understands enrichment limitations and has a plan to maximize match rates
Troubleshooting
Low enrichment match rate
Symptom: Megahit only matched a small percentage of subscribers with LinkedIn data
Cause: Many subscribers use personal email addresses (Gmail, Yahoo) that are harder to match
Solution: Focus outreach on the subscribers that did match — even a 20% match rate on a 10K list gives 2,000 enriched contacts. For unmatched subscribers, consider asking for work email in a survey or progressive profile form.
Not sure which subscribers to target for sponsorship outreach
Symptom: Have enriched data but don't know who to pitch
Cause: Need to filter by the right job titles and company types
Solution: Filter for titles containing "Marketing," "Growth," "Brand," "Partnerships," "CMO," "VP Marketing," or "Founder" at companies with 50+ employees. Cross-reference with SponsorGap to confirm they have active newsletter ad budgets.
ESP not supported
Symptom: Your email service provider isn't in Megahit's integration list
Cause: Megahit supports 9 ESPs — yours may not be included
Solution: Export subscribers as CSV from your ESP and import into Megahit manually. Check Megahit's website for integration updates.
