If a business wants to communicate with a customer, the best way to do it is through an email.

According to Hubspot, 86% of consumers would like to receive promotional emails from companies they do business with at least monthly (with 15% preferring daily emails). Emails are the quickest way to announce a sale, share company news, or remarket to previous customers.

Recent research found that email marketing is popular across generations, enabling businesses to reach broad audiences effectively and inexpensively.
