The email service provider (ESP) refers to a company or an online organisation that provides automated email sending as a part of email marketing. Except you have a company that is large enough to have its own technical support for e-mail, you will surely need the services of an ESP.
An ESP provides its customers with the technical infrastructure and an optional software tool to manage the sending of emails qualitatively and quantitatively. Email marketing campaigns, mailings, and regular newsletters are completed using an ESP.
There is an increasing number of email service providers, one differing greatly from another in terms of portfolio, service, the infrastructure used as well as the measures for spam control. The services ESP offers may include: Providing templates for email design, targeting, segmenting, spam control, technical support, e-mail address management, message and basic reporting.
