Email marketing is such a critical component of business for most companies (with the rare exception) because you able to communicate with your audience in the place they spend a good chunk of time (their inboxes). You also have the added benefit of building an asset (an email list) that no external platform (I’m talking to you Facebook) can mess with.
Now, you can automatically send highly relevant emails encouraging them to buy the product or service they were considering. Customers who received multiple abandoned shopping cart emails are 2.4 times more likely to complete the purchase than those who receive only one followup email, according to Experian. Try sending the first message one day after, a second message 48 hours after, and possibly a third message within three or four days of abandonment.
