In one line

Email marketing is direct, owned-channel communication with prospects and existing customers — and remains one of the highest-ROI tools in the CRM and retention stack.

Going deeper

Email is one of the few channels where you can reach a customer without paying a platform tax in between. Because it sidesteps algorithm changes, rising CPMs and cookie restrictions, it stays the cornerstone of any owned-channel stack.

The classic metric set is open rate, click rate, conversion rate and unsubscribe rate. After Apple's Mail Privacy Protection rolled out, open rates inflated noticeably, so most teams now lean on clicks and conversions as the more honest signals.

Behavioural automation tends to outperform big batch sends by a wide margin. Trigger-based flows — day-three onboarding, 24-hour cart abandonment — typically convert several times better than a generic newsletter blast.
