What Is ESP?
An email service provider (ESP) is a technology company providing email marketing service, allowing users to build and manage a list of subscribers and send email campaigns. Email service provider is distinct from an email client (like Gmail, Yahoo, Hotmail or Outlook) because it enables users to send out larger quantities of email. ESPs usually also offer some advanced features that help users to target and automate their email marketing processes.

Small and mid-size businesses will generally need different features and functionality than large enterprises, so each company should choose the best email service provider for their needs.
