In this post we round up some essential email marketing statistics from around the web, updated for 2019.

Email remains one of the best performing  marketing channel. The DMA says that, for every $1 spent on email, it delivers average ROI of $32.

How Much Is an Email Address Worth?

The answer to this question will vary by industry, and how effective a company’s email marketing is.

Experian estimates that the average email address is worth £84.50.

This is a cross-industry average and will differ greatly, depending on the typical customer lifetime value. So, for example a travel email address may be worth £236, while retail is much lower at £79.

Whatever the exact figure for each industry, it does underline the value of email acquisition to build a database.

Email Marketing Statistics: ROI and Sales

There have been plenty of foolish posts predicting the death of email over the years, but it still delivers the best return on investment of any marketing channel.

The Econsultancy / Adestra 2018 Email Marketing Census confirms this, with almost three quarters of  company respondents rating it as good or excellent for ROI. The highest proportion of any channel cited.

The average proportion of total sales that client-side marketers can attribute to their email marketing is 19%, down from 202% the previous year.

Email Optimization Strategies

The Adestra / Econsutancy Email Marketing Census found that a minority of companies have an email optimization strategy which they would describe as ‘quite’ or ‘very’ advanced.

The report also looks at the specific tactics used to improve emails for mobile recipients. What have you done to optimise email marketing for mobile?

Attitudes to Emails Not Optimized for Mobile

Mobile optimized emails are a must, but as the previous charts show, some companies are less than advanced in their email optimization strategy. As more and more emails are opened on mobile, failure to ensure that emails are readable on mobile devices represents a huge missed opportunity. According to a consumer survey, 42.3% will simply delete non-optimized emails, while just 11.3% will read it anyway.
