Verdict
The clearest difference is in-app purchases: Letswork at none against Spark Mail's 10. Letswork also leads on rating (5.0 vs 4.6) and review sentiment (78% vs 61%). Spark Mail's advantage is ratings volume (83K vs 5) and update cadence (weekly vs fortnightly). On price, ads, device support and iOS requirement there is nothing between them.
