Email is dead. Or so people keep on saying. Endlessly But, of course, it’s not.
On the contrary, email as a workplace communication tool, is being used by more people in more companies than ever before.
According to the Radicati Group Email Statistic Report 2021-2025, the total number of business and consumer emails sent and received per day will have grown from 319 billion in 2021 to over 376 billion by 2025. So much for being dead.
What has changed, and continues to evolve, is that while email continues to be the most widely used workplace comms tool, it’s now just one of many that companies must have to reach and engage all their employees wherever they are: in the office, on the road, the frontline or the factory floor.
From how to assess your current use, to important measuring techniques and stakeholder analysis, to email planning, structure, and style, this guide is essential for anybody who wants to get the most out of the world’s most widely used and effective workplace communication channel.

Internal communication is under real pressure. IC teams are expected to support leaders, shape culture, and deliver relevant, personalized communication to an increasingly diverse audience—all while operating at greater speed and scale than ever before. AI arrives at the right moment. It doesn’t replace communicators; it elevates them. Applied well, AI sharpens the fundamentals of effective communication: diagnosing issues, shaping the narrative, guiding leaders, and delivering messages that connect people to purpose and progress. At its best, AI accelerates drafting, adapts content for different formats, improves accessibility, and surfaces insights about what’s landing. Without governance, though, it can create noise or risk. The opportunity for IC teams is to bring AI in thoughtfully, with governance and human judgment at the center. This guide shows how to do exactly that. Inside, you’ll find practical guidance on when to use AI, where humans remain essential, how to establish guardrails, how to prompt effectively, and how to scale AI responsibly across channels and teams.

Clear answers on security, data protection, integrations, deployment, AI governance, and enterprise scalability.
