ESP (Email Service Provider)

When people ask, “what is an ESP?”, the basic answer is the following: an ESP (which is an abbreviation for an Email Service Provider) is a platform that helps businesses send lots of emails to many people at once. The ESP email meaning in easy words is that it works like a digital post office for marketing emails, making sure messages are delivered right to inboxes, not lost or marked as spam.

 

What does an ESP mean for marketing?

 

In marketing, an ESP offers a tool used to create, send, and track bulk emails such as newsletters, promotions, and automated messages. Other useful features include templates, automation, and analytics to make email marketing campaigns launch and management easier. 

 

ESP vs. regular email

 

It's also important to note that while Gmail or Outlook also help you send emails, they are not considered ESPs because they neither allow bulk email sending nor offer subscriber lists, or performance tracking like marketing platforms (e.g., UniOne, HubSpot, ActiveCampaign).

 

ESPs, on the other hand, are aimed at businesses that need to send large-scale email campaigns and track how well those emails perform. So, if you’re about to send a promo to 100 or more recipients and want it to be properly delivered while also being informed of how many recipients actually received and read it, ESP is your way to go.
