There are many reasons online businesses are valued now more than ever. In fact, according to a recent study by business tycoon McKinsey Digital, “75 percent of people using digital channels for the first time indicate that they’ll continue to use them when things return to normal.”

Whether your business has shifted from communicating from in-person to providing testimonials or sales promotions online in light of the pandemic caused by COVID-19, it’s essential to make the most of your time by managing your email workflow using an email marketing platform in 2024, and beyond.

What is an ESP?

Email Service Providers (ESPs) are tools that can help revolutionize the way you do business. Not to be confused with an MTA, the back-end software that sends your emails, ESPs are front-end platforms that allow users to set up subscriber lists, create templates, and schedule their messaging and email marketing campaigns.
