What is an email service provider (ESP)?

An email service provider (ESP) is a service that enables businesses to send email campaigns to an audience (often referred to as a a list of contacts or "subscribers").

Subscribers opt-in to receive email from the business — in the form of newsletters, marketing messages, product updates, and more.

Why should you use an email service provider?

Unlike using an email service like Gmail for personal use, an email service provider is designed to enable a business to send thousands, if not millions of emails to an audience all at once.

Choosing an ESP can be a smart investment for any business.

With an ESP, businesses can communicate with their audience at scale, in a highly effective and economical manner. Not only can you update your audience at scale, you can also automate messaging to your audience, saving your team time and money.

With the right ESP, you can give your subscribers, prospects, and customers a highly engaging, tailored communication journey, and drive up your engagement rates, retention rates, increase lifetime value, and dramatically improve brand loyalty.

What are some examples of ESPs?

There are many email service providers to choose from, and the list is growing all the time. You won't need to look far to find some big names that offer email sending functionality.
