30 Insane Email Marketing Statistics That Prove the Enduring Power of the Marketing Channel

Email Marketing

Many argue that email is dead. Would you agree?

An email marketing plan is old-fashioned and not as effective as its contemporary siblings, mobile marketing and social media.

Sure, people are on their phones for social media—the global average was 62.3%— and while these prove to have some merit, is email completely gone?

I, for one, check my inbox daily, but it’s usually out of habit. Mindless scrolling through the mishmash of emails from banks, subscriptions, and social media updates.

But occasionally, I’d find myself reading email headings that read, “We slept in the woods for 5 days…” or “I’m giving away my house.”

Of course, initially, I’d get hooked and ask myself, “When did I ever sign up for real estate newsletters?” only to check the email and see that they were actually from Noah Kagan, Chief Sumo at AppSumo.

Kagan helps businesses launch by providing business-to-business email marketing and real-life advice that they can use.

This technique of staying personal and relevant turned what was once mindless scrolling into a weekly thing I looked forward to.

With these simple yet revolutionary marketing methods working to a high degree, more than 347 billion emails are sent, reaffirming the enduring strength of email marketing strategies for digital marketers.

Here are 30 incredible statistics to demonstrate why email should remain a cornerstone of your digital marketing strategy. Ready? Let’s dive in.
