Case Study: Growing a Curated List with Zero Marketing Budget
Growing a curated list or online directory from scratch is a daunting challenge, especially when you have zero marketing budget. Many solopreneurs, indie hackers, and side hustle creators face this same uphill battle: how do you build traction, get visibility, attract users, and generate revenue without spending a fortune?
In this case study, we’ll explore how directory owners have leveraged Nurturing Mails to automate outreach and grow their curated lists organically — with no ad spend. We’ll walk through the process in detail, highlight the tools and strategies used, and provide actionable tips for others looking to do the same.
Initial Challenges Faced by Directory Owners
1. Zero Traffic, Zero Users
Every curated list or directory starts with an empty state. There are no users, no entries, and no organic traffic. This makes any traditional marketing effort (like SEO or content marketing) a slow build.
2. Difficulty in Outreach
Manual outreach can be time-consuming and inefficient. Sending hundreds of emails manually every week is unsustainable — especially when trying to personalize each one.
3. Limited Bandwidth
Many directory owners are solopreneurs juggling multiple roles. Spending hours daily reaching out to startups is time they can’t afford.
The Turning Point: Leveraging Product Hunt Launches
Directory owners discovered that Nurturing Mails offers a unique opportunity: automated and personalized email outreach to founders who just launched their product on Product Hunt.
Product Hunt is one of the best platforms to find high-quality, early-stage startups actively searching for visibility and backlink opportunities. Every day, more than 50 new products launch on Product Hunt. Most directory builders miss this opportunity entirely — unless they have an automated solution in place.
Why Product Hunt Matters
- Founders are more likely to engage — they are in “promotion mode.”
- They’re looking for press mentions, backlinks, directories, and reviews.
- Engagement is time-sensitive — the first 48 hours post-launch matter a lot.
This is where Nurturing Mails shines. By offering automated personalized emails at just the right time, it builds rapport and relevance when it’s needed the most.
How a Directory Got Its First 200 Submissions
This case involves “IndieToolBox” — a curated list of tools built for indie hackers. The owner, a solo founder, needed a way to consistently add new and relevant tools without spending hours on outreach or running paid ads.
The Strategy Used
Using Nurturing Mails, he synced his directory with automated outreach that looked like this:
- Email sent within 6 hours of a product launching on Product Hunt
- Email included founder’s name, product name, and congratulations on their Product Hunt success
- Non-pushy message inviting them to their niche-curated directory for added exposure
With minimal setup, he began reaching out to 10-15 new startups each day — completely automated thanks to Nurturing Mails’ features.
Results
| Metric | Before Nurturing Mails | After 60 Days with Nurturing Mails |
|---|---|---|
| Directory Submissions | 23 | 210 |
| Traffic (Monthly) | 91 | 2,400 |
| Backlinks | 10 | 230+ |
| Revenue from Paid Listings | $0 | $690 |
Key Takeaway
Automated, personalized, and well-timed email outreach can significantly accelerate your directory growth trajectory — without spending on PPC ads or hiring a sales team.

Nurturing Mails did more than just send emails.

2. Curation Platforms & Communities
Once the directory had momentum, it was listed on the following platforms for even more organic traction:
- Uno Directory – A directory of directories
- Aura++ – A curation platform for digital products
- Praneet Brar – Blog covering indie hacking tools
This compound effect of initial directory submissions and community exposure led to better SEO, more backlinks, and higher authority in the niche.
3. Data Tracking & Optimization
Using tools like Google Analytics 4, Ahrefs, and EmailAnalytics, the indie founder tracked user behavior, open rates, conversion rates on submission forms, and pages that performed best. This data helped optimize outreach templates and call-to-actions.
Best Practices for Directory Builders
If you’re just starting out or trying to scale your directory with minimal resources, here are some best practices inspired by this case study:
- Start Small, Target Narrowly: Focus on a sub-niche (e.g., “AI Chrome extensions” instead of just “AI tools”). This increases relevance and submission rates.
- Use Automated Outreach Platforms: Save time by using Nurturing Mails to do outreach for you without sacrificing personalization. It’s simple, reliable, and built for your exact goal.
- Optimize for SEO with Fresh Submissions: Every new submission brings potential backlinks. The more submissions you get from early-stage founders, the more authority your directory gains.
- Combine Automation with Community Sharing: After realizing traction, share your directory in niche-specific communities on Indie Hackers, Hacker News, Mastodon, and Reddit — especially subreddits like r/SaaS or r/SideProject.
- Add Value, Don’t Just List: Include founder quotes, testimonials, or quick reviews to enhance credibility and retention. Entry quality matters as much as quantity.
Common Questions When Scaling a Directory
Many early-stage builders ask questions like:
- How many emails can I send per day with Nurturing Mails?
- The platform sends emails at a configurable 15–20 minute interval to optimize inbox delivery. On average, users send to 40–60 founders per day safely.
- Can I customize templates for different niches?
- Yes. The tool allows you to create multiple templates depending on the audience/product type.
- Is this only for new directories?
- No. Many established directories also use this to scale into new niches or verticals by testing different outreach strategies.

Growing a curated list or directory from zero is no easy feat — especially without a marketing budget. However, with smart automation and real-time outreach powered by platforms like Nurturing Mails, it becomes entirely possible to build momentum organically. By combining real-time lead sourcing with personalized emails, you meet founders exactly where they are — right after their Product Hunt launch, when they’re most receptive.
