Reasoning
Consolidated each URL to a single canonical view: PCMag → high, EmailToolTester → low, TechRadar → advanced, Pipedrive official → low. Mapped to canonical levels (low, medium, high, advanced). Weighted by source confidence for the chosen opinion: low = 0.90 (EmailToolTester) + 0.65 (Pipedrive) = 1.55; high = 0.80 (PCMag) = 0.80; advanced = 0.95 (TechRadar) = 0.95. The total for 'low' is highest (1.55), making it the most supported consensus despite some high/advanced signals from individual sources.
