Email Marketing Statistics By Market Growth And Revenue (2026)

Introduction

Email Marketing Statistics: In 2026, email marketing will continue to be one of the most measurable and effective channels of digital marketing, as it has been the case for years. The global email audience is approaching 4.73 billion users, and the revenue brought in by email marketing has reached billions of dollars.

Litmus, Omnisend, Statista, HubSpot, Mailchimp, and Google research indicate that the channel evolved from an approach that focused on mass communications into a system that involves data-driven techniques, automation, personalization, AI, behavior triggers, and first-party data technologies. Industry benchmarks indicate a return of around $36-$42 on every $1 invested, and sophisticated ecommerce applications can show even higher returns.

However, the processes of changing privacy laws, the appearance of AI-generated content, requirements concerning delivery, and loss of reliability of open rates are forcing marketers to rethink how email efficiency is calculated.
