The Bottom Line
Cold email works in 2026, but the bar for quality is higher than ever. The teams hitting 8%+ reply rates share three traits: hyper-targeted lists (under 500 contacts), deep personalization (beyond {{firstName}}), and multi-step sequences with automatic follow-ups.
In ClickReach, you can track all of these metrics in the analytics dashboard — per-sequence, per-step, and per-mailbox — without relying on pixel tracking that inflates your numbers.
