What is an Email Service Provider (ESP)?

Email service providers are businesses offering marketing tools entrepreneurs, eCommerce managers, bloggers, SMEs, and fortune 500 companies can use to automate, segment, and build sustainable relationships with customers through emails. 

On a general level, ESPs can help you set up an email marketing list, create campaigns, design automated workflows, send promotional emails and newsletters, manage your contacts and enjoy seamless integration of marketing activities. 

Why Do You Need an ESP?

Every successful business was once someone’s idea or intention for growth. Most companies started with a single customer, somehow found a second, and on and on until they became unicorn companies.

You’re here, so we presume you want to power a successful business. Maybe you just landed your first client or first 1000th customer; it doesn’t matter.

To further your pursuit of success, you need a communication process that allows you to simultaneously reach out to your newly found clients without much Ado. And that’s where ESPs come in. 

Email marketing service providers use customer interaction and behavioral analysis to send personalized messages to the right customer at the right time, helping you swiftly cultivate a silver bullet path to success. 

And now, with multiple ESPs available, you can send more personalized emails while spending less. You need an ESP offering features and services in line with your marketing requirement for gratifying results.

So before we go any further, let’s look at some factors to consider when foraging the internet for a reliable ESP.

Factors to Consider When Choosing an ESP

Editors Flexibility: the features and options an ESPs email editor offers to determine your clients’ type of email. If your choice ESP offers rich drag and drop editors with immaculate filters and unique templates, your email will be just as good. Opt for free trials or free plans to get a first-hand experience of your choice ESP editor. 

Autoresponder and Automation Sequence: automated sequence consists of emails built around if/then trigger (based on a customer’s interaction with your digital platforms). In contrast, autoresponders consist of a series of emails arranged quickly. Before settling for an ESP, make sure they offer both services. 

Interface: if you plan to design your emails yourself, look for an ESP with a simple and easy-to-navigate interface with many templates. The interface of choice ESP speaks volumes about the overall output of each marketing campaign or newsletter. If you have a design team, seek their consent before opting for any ESP.

Support: as an eCommerce manager or blogger, consumers from different parts of the world will speedily use your sign-up form if they deem your services valuable. Your email marketing can’t thrive on clockwise or geographical timing – you’d most likely serve clients from different parts of the globe. Don’t settle for an ESP not offering 24/7 support service.

Email deliverability: What’s your choice ESPs track record? How often do their emails land in the receiver’s inbox? As you ask their support team these questions and explore the internet for reviews and feedback on the ESPs overall performance.

Budget: we placed the need to weigh your budget last on purpose. We know that most start-ups and SMEs love to settle for the cheapest offer on the block, and that’s something we want you to avoid. Consider all the factors we listed above before considering your budget because you can constantly rethink the expense.

Sometimes, the dire requirement for actionable insights to back your email marketing activities determines your choice of ESP.


With millions of users across 175 countries, it’s safe to say Mailchimp knows what works and what doesn’t. 

Mailchimp uses its customers’ data, activities, and interactions to update its email strategy. Ensuring it’s got flexible solutions for enterprise users and a simple interface for bloggers.

The 80-pound Gorilla, as Mailchimp’s logo foretells, offers over 300 integrations. Some of which include its in-apps ability to help users sell their products and book meetings, social media post scheduler, an email marketing calendar, etc.
