Email marketing is an online marketing strategy that involves sending targeted messages to an email list to promote products, services, or raise brand awareness. It is one of the most direct and budget-friendly ways to engage customers, increase sales, and build loyalty.
Unlike banner ads, which can appear on various platforms and may be ignored, email outreach delivers messages straight to recipients’ inboxes, ensuring direct contact regardless of the device they are using—whether it's a desktop, tablet, or mobile phone.
Organisations use email marketing for a variety of purposes, including:
Promotional campaigns – Announcing new products, sales, or special offers.
Customer retention – Sending exclusive deals, loyalty rewards, and updates.
Automated engagement – Following up with abandoned carts, sending welcome emails, and re-engaging inactive customers.
With the right email marketing strategy, marketing teams can create highly personalised successful email campaigns that drive customer engagement and long-term success.
Email marketing consistently delivers one of the highest ROIs of any digital marketing channel. Research shows businesses can achieve an average ROI of 3,600%, meaning that for every £1 spent, they can generate £36–£45 in revenue.(1)
