Verdict · confidence: high
The email verifier niche is a 'maybe' due to high demand (14,800 monthly searches) and stable trends, but entry is blocked by a 'closed' search landscape where all checked SERPs are strong. App stores are contested by giants. Economics are average with moderate CPC ($5.87). The decision is 'maybe' because while the market is large, organic acquisition is nearly impossible without significant budget or a unique angle, and paid acquisition is expensive.
