Methodology and sources
Every figure is computed live from the Toolradar catalog, published Email Clients tools only. Ratings and review counts are aggregated across third-party review platforms (G2, Capterra, Trustpilot, SourceForge) and are not the site's own reviews. Added in 2026 means added to the Toolradar directory this year, not the vendor's launch date. Leaderboards apply a 500-review floor. See how we rate.
