We all know quality over quantity. But when it comes to email marketing statistics in this day and age, it can be hard to tell those two apart.

Let’s face it: There’s a ton of data out there vying for our attention. And as marketers, we know how important it is to let the hard facts guide our decisions.

But what happens when those facts are faulty? 

It’s true — your stats are only as good as your sources. And these sources get misused and misconstrued all the time! Whether the data reflects a very specific industry, or the experiment was poorly conducted, or the sample size was less-than-ideal, or the info is just plain old, there are any number of things that can go wrong in our noble pursuit of a bigger picture.

In other words, the road to unsound research is paved with good intentions.

So with this in mind, I set out to compile the highest quality list of email marketing stats for 2025, leaving no stone unturned in my quest for knowledge from only best-in-class sources. 

Below you’ll find everything you need to understand the state of email marketing currently, including: 

Plus, I’ve included a snapshot into the methodologies behind some of these stats, so you can have full confidence in each figure you see.

Let’s get started.

Essential email marketing statistics

The number of outbound emails increased 15% in the last year, and continues to make up over 80% of all outbound messaging. Salesforce 

The global email market was valued at $8.5 billion in 2021; by 2027 it is expected to reach nearly $18 billion. Global Email Marketing Industry Report

Global email volume rose by 14 percent from 2020 to 2021. Initially seen as a disruption, it has become seen as the “new normal.”Validity

Stats spotlight
