Kirsty Wilson 7 min read

Email marketing statistics can help marketers understand the buying habits of their subscribers. They can also help you build long-lasting relationships with your customers and maximize your ROI.

Email metrics such as open rates, click-through rates, and conversion rates are crucial to marketers. And they can help measure the success of an email marketing campaign.

So, you’ve created a campaign, and you’ve put in the work. But you’re not yielding the results you expected.

It’s not your fault.

On average, only around one-fifth of all emails sent are actually opened.

The trick then is finding new ways to entice your readers to open your emails and take action.

Email Marketing Defined

You may be thinking, “wait, does email need marketing?

While email marketing has been around for decades, it’s more than sending messages to inboxes to promote your products or services.

Boost subscriber engagement and promote your brand with engaging, timely, and relevant emails. It's also a great way to keep your audience engaged between purchases.

Your email marketing campaign may include brand updates, promotions, and exclusive deals. This can help to convert prospects into customers and incentivize customer loyalty.

Email marketing is one of the most cost-effective and conversion-rich forms of marketing out there. It’s potent, persuasive, and can deliver some incredible results to your eCommerce store.
