How does Stroby work?

Stroby uses AI to match businesses with the most relevant influencers and creators based on niche, audience demographics, and budget. Both sides opt in before a deal is made. Payments are held in escrow until the placement runs and proof of performance is submitted.

How much does Stroby cost?

Stroby is completely free for influencers and creators. For businesses, we charge a commission on each successful transaction. There are no upfront fees, subscriptions, or hidden costs.

How do you verify metrics?

We use direct API integrations with major platforms to pull real audience and engagement data. For platforms without API access, we use verified screenshot submissions with timestamp validation.

What is the placement guarantee?

If actual performance metrics fall significantly short of what was promised, Stroby will issue a partial or full refund to the business from the escrowed funds.

How does the escrow system work?

When a partnership is booked, the business pays into Stroby's escrow. The funds are held securely while the placement runs. Once proof of placement is submitted and metrics are verified, the funds are released to the influencer or creator.

How long does matching take?

Our matching engine runs daily, so suggestions can arrive as soon as the day you finish onboarding. Timing depends on your niche and current sponsor inventory.

What niches does Stroby support?

Stroby supports SaaS, Marketing, Sales, Fintech, AI, E-commerce, Health & Wellness, Travel, Fashion, Sports, Education, Entertainment, and many more. If your niche isn't listed, sign up anyway — our AI will find you the best matches.

Can I use Stroby if I'm an agency?

Yes! Agencies are welcome. You can onboard each of your clients individually, manage multiple campaigns, and take advantage of our AI matching across all of your accounts.

How much should I charge for a newsletter sponsorship?

Price a primary sponsorship at your niche CPM times your reach in thousands. Most newsletters land between $20 and $130 CPM depending on niche and engagement, so a 10,000-subscriber B2B newsletter with a strong open rate can charge roughly $850–$1,100 per primary slot. Use the calculator above for your exact numbers.

What is a good CPM for a newsletter?

A good newsletter CPM is $20–$50 for general consumer audiences and $50–$150 for specialized B2B niches like finance, SaaS, and sales. Highly targeted or professional audiences command the top of that range because sponsors value intent and relevance over raw list size.

Does subscriber count or open rate matter more?

Engagement matters more than size. An 8,000-subscriber newsletter in a tight B2B niche with a 55% open rate routinely out-earns a 50,000-subscriber general-interest list. Lead every sponsor pitch with your open rate and click-through, not your subscriber count.

What are typical newsletter sponsorship rates by niche?

Sales, finance, and politics/government are the highest-earning niches ($90–$200 CPM); B2B SaaS, healthcare, legal, and local newsletters sit in the middle ($50–$130); lifestyle, travel, food, and gaming are lower ($12–$40). The full table is on this page.

How do I price a dedicated email versus a primary slot?

A dedicated send (the sponsor gets the whole email) is worth roughly 3× a primary in-content slot. A secondary mid-content placement is about 60% of primary, and a footer classified is about 30%. Offer all four tiers so sponsors can pick a budget.

How much can a 10,000-subscriber newsletter make from sponsorships?

It depends entirely on niche and engagement. A 10,000-subscriber general newsletter might earn $150–$250 per primary slot, while a 10,000-subscriber B2B or finance newsletter with high opens can earn $850–$1,300 per slot — and more for dedicated sends.

Should I charge a flat rate or CPM?

Start with a flat rate derived from your CPM (CPM × reach ÷ 1,000) so sponsors see one clear number. Move to explicit CPM pricing once you have consistent delivery and open-rate data to justify it. A 'founding sponsor' discount is a legitimate way to close your first deal without permanently anchoring low.

How newsletter sponsorship pricing works

The standard formula is CPM × (subscribers ÷ 1,000). CPM (cost per mille) is the price per 1,000 readers a sponsor reaches. Pick your niche’s benchmark CPM, multiply by your list size in thousands, and you have a defensible primary-slot rate.

Then adjust for engagement. A newsletter that opens well above the ~38% baseline earns a premium; one below it should discount, because sponsors are really buying attention, not addresses. Finally, set your tiers — a secondary mid-content placement is ~60% of primary, a footer classified ~30%, and a dedicated send (the whole email) roughly 3×.

For your first deal, a flat rate derived from your CPM is easier for sponsors to say yes to than a CPM negotiation. A one-time “founding sponsor” discount is a legitimate way to close without anchoring your rate low forever.
