What is an Email Marketing Service

You might be thinking this one is a no-brainer. The obvious answer is that an email marketing service is a company or software that facilitates sending emails out to a list of contacts.

Ten years ago, you’d more or less be correct in that answer. But today, the best email marketing services look more like full-fledged CRM systems. That’s because they compete with some of the best CRM’s out there, like HubSpot, which many people view as a CRM but absolutely can handle email marketing.

The difference is that a true CRM has far more workflows to help manage a sales team than most focused email marketing software solutions.

Today’s email marketing software is delivering all sorts of products, including marketing forms, customer segmentation, behavioral targeting, marketing automation, dynamic content, and analytics to help understand your customers.

Free vs. Paid Services

The difference in most cases comes down to the features and number of contacts allowed. Almost all of the services on this list have a free version that will do just fine for small companies.

When your business gets to the point of wanting its own branding and has grown to a certain level, it’s worthwhile to upgrade to paid versions of these tools.

The paid versions often have features you may want even before a contact list gets too big. Things like A/B testing, customer segmentation, and automation can really help supercharge your email campaigns. But that’s only if you take the time to understand and use these tools in the right way. If that’s the case for your business, then consider a paid version over free.

The Bottom Line

Email marketing has stood up to the test of time as one of the best ways to engage customers and make sales. That makes your email marketing service one of the more important software selections you make.

The good news is because email has been around so long, there is no shortage of options. Every email service on this list is capable of helping you achieve your goals.

Take the tools these companies deliver and start learning how to grow your email list today more effectively. Whether it delivers better relationships with existing customers, or helps close deals with new ones, it’s critical you use this marketing tool in business today.
