In a way that direct, or other forms of marketing can never hope to be, email marketing allows you to determine a tangible return on investment for all of your efforts. Through email marketing, you can track who has opened your message, what mail client they use, when they engaged with your message, and what link they’ve clicked on. Email marketing is great for taking advantage of impulse buying. There aren’t many other marketing platforms which allow customers to go from witnessing an offer to purchasing an item within two clicks of a button. With a tempting call to action and a link straight to the checkout, email newsletters can drive sales like no other channel.
