77% of marketers report that email user activity has noticeably increased over the past year. Analysts predict that companies' email marketing revenue will grow to $11 billion by the end of 2023. Now is the perfect time to pay more attention to email marketing and make your company's emails even better with specialized services.
What is an email newsletter service and why do you need one
An email marketing service is a specialized platform for optimizing email campaigns. There are two types: ESP and CDP.
ESP platforms handle sending emails to your customer base. They let you create beautiful emails, track their performance, and automate the sending process itself.
CDP platforms help gather customer information from multiple sources and store it in one place. These services make it easy to analyze subscribers' personal data.
Both types of platforms work to help you improve communication with your customers.
