In the world of email, the email service provider (ESP) is a key component of any marketer’s strategy. They offer a suite of services that includes sending, receiving, and storing emails, as well as tools for analytics and automation. ESPs are instrumental in ensuring that emails are delivered to the right inbox and not marked as spam.
Basically, love ‘em or hate ‘em, we need our ESPs. And we all want to make sure we’re using the best tools for the job at hand. (Or at keyboard, at mouse, at screen reader…you get the idea.)
