📈 How many results can you scrape with Substack Email Scraper?

The scalability of the Substack Email Scraper depends on factors like keyword depth, domain filters, and email availability within public Substack posts and profiles.

When using broad keywords such as marketing, growth, or startup, you can gather dozens—or even hundreds—of Substack leads depending on the content saturation of that niche. Narrow keywords like astro-philosophy will return fewer but highly targeted results.

The maxEmails parameter lets you control the scrape size from 1 to 10,000 emails. This allows you to control cost, runtime, and precision.

With the cost-effective engine, performance is optimized to scan more pages quickly, making large-volume searches significantly faster than traditional scraping methods. The legacy engine, while slower, increases reliability for very niche keywords.

In short:

• ⭐ Small searches (10–50 emails): Fast & accurate
• ⭐ Medium searches (100–500 emails): Ideal with cost-effective engine
• ⭐ Large searches (1,000–10,000 emails): Requires broad keywords + long runtime

The scraper is built to scale smoothly regardless of your project size.
