How effective is email marketing? 

There is no doubt that email marketing is a powerful strategy for any brand or industry. Email marketing is a form of direct marketing since it requires one’s email address and consent to receive business promotions and communications.

Since email communication began in the 1970s, it has been exploding ever since. 99% of email users check their inbox every single day and the rise of mobile devices has made email even more accessible. It’s no wonder that marketers are leveraging email marketing and with the statistics to back it up, it works.

So, how effective is email marketing? You can find out with one vital metric: ROI.

ROI stands for return on investment. Measuring ROI is an essential metric to determine exactly how successful a campaign is. When comparing email marketing to other common digital strategies, email marketing’s ROI can’t be beaten. Email marketing ROI is so high thanks to email’s easy automation, low barrier to entry, and minimal costs overall.

What is the average ROI for email marketing?

1.  For every $1 spent on email marketing, marketers make $42

  1. Hi Luisa, many insightful email statistics here.
    I’d say my favorite email statistic is the 31st about email subject lines.
    The subject line is the most important part of an email. Because without an enticing subject line, subscribers won’t click your email in the midst of the hundred they scroll through daily.
    As David Ogilvy (and other top copywriters) have stressed, marketers need to spend more time on the subject line (or headline) and show benefits for subscribers.
    Your advice about using emojis is also effective in attracting attention.
    Great post!
