What Is an Email Service Provider (ESP)? + Best Ones for 2024

Everyone talks about email marketing being the marketing channel with the highest revenue. And that’s true if you really put the time and effort into it, use your customer data, and A/B test like crazy. None of that is possible without the right email marketing tool.

You need a good Email Service Provider (ESP) to set up the right automations, create stunning email campaigns, and continuously convert leads and delight customers. Here’s how to find the right one for your business.

What is an ESP?

An Email Service Provider (ESP) is a technology platform that facilitates email marketing campaigns. More than just conventional email software, ESPs empower businesses to create, manage, and optimize their email marketing initiatives efficiently. While they might sound similar, there's a significant distinction between ESPs and basic email software.

ESP vs. Email Software

Email software is akin to a basic communication tool that allows you to send and receive emails. These are your Gmails and Outlooks. These tools help you type, send, and receive emails. They're handy for personal communication and managing your inbox but lack the robust features necessary for executing effective email marketing campaigns.



On the other hand, ESPs or email marketing platforms are built for email marketers and offer a suite of advanced features that empower businesses to create personalized, targeted, and automated email campaigns. These are tools like Klaviyo, Mailchimp, Constant Contact, or Omnisend.

They offer features like bulk email sending, analytics, automation, personalization, and better email delivery. They let you upload your email list and send personalized emails to different segments. So, if you're running a business or handling a large number of emails, an ESP is the way to go.

Top 9 Reasons You Need an ESP

Doing email marketing without an email marketing tool is like trying to write an email on a dumb phone. It will take you ages. You can't just send individual emails to your customers. You need additional features like segmentation, personalization, A/B testing, automated email flows, and deliverability features.

Here are the top reasons why you need to use an ESP.

1. Email deliverability

The success of your marketing emails depends on whether your emails land in the recipient's inbox. ESPs employ sophisticated techniques to enhance deliverability rates and reduce the chances of your emails getting flagged as spam.

3. List management

An ESP simplifies the management of your subscriber lists and allows you to segment and organize your contacts effectively for targeted messaging.

4. Easy-to-use email templates

Creating visually appealing emails is a breeze with pre-designed templates and built-in email journeys. This saves time and ensures your emails are consistent and professional.

5. Segmentation and personalization

Segmentation and personalization are paramount to email marketing success. ESPs enable you to tailor your content based on user behavior and preferences, leading to higher engagement rates. You can add personalized images, mention previously purchased products, and even embed videos into your emails.

6. Email automation

ESPs offer advanced automation features and allow you to set up triggered emails based on user actions, such as a welcome email series, abandoned cart reminders, and shipping notifications. You can also target visitors based on the product pages they saw, what they added to their cart, or which blog posts they’ve read.

7. Marketing funnels

Crafting effective marketing funnels becomes seamless with ESPs. You can guide subscribers through a well-defined journey, from initial contact to conversion. You can set up a Mailchimp form (or any form that connects to your tool of choice) and collect new subscribers.



8. Tracking, analytics, and reporting

Understanding the performance of your campaigns is essential for continuous improvement. ESPs provide comprehensive analytics that help you gauge open rates, click-through rates, and other vital metrics.

9. Time saving

The efficiency of ESPs streamlines your workflow, saving you time and effort. You can schedule emails in advance, which allows you to focus on other crucial aspects of your business.

How to choose an email service provider

Selecting the right Email Service Provider (ESP) is a strategic decision that can significantly shape your marketing journey. Given the uniqueness of every business, not all ESP features will be equally relevant. Here's a closer look at the key features that should guide your selection.

1. Email marketing automation

Engaging subscribers requires personalized attention. Advanced automation capabilities offered by ESPs empower you to create tailored experiences, delivering the right message at the right time. By automating processes like welcome emails, abandoned cart reminders, and personalized recommendations, you can deepen connections and drive conversions.



2. Lead capture forms

Building a strong subscriber list is fundamental to email marketing success. Effective lead generation hinges on user-friendly, customizable forms that seamlessly integrate into your website. Tools that provide these forms simplify the process of capturing valuable leads, contributing to sustained growth.

3. A/B testing

Optimizing campaigns demands data-driven insights. A/B testing enables you to experiment with different versions of your emails to see what resonates best with your audience. This iterative process helps improve your conversion rates and boosts the overall effectiveness of your email communication.

Aspects of your email you should test:

• Your email subject lines + preview text
• The from email address
• The body or content of the email
• The CTA text

4. Audience segmentation

Not all subscribers are the same, and audience segmentation empowers you to craft messages that cater to specific segments. Robust segmentation options—ranging from demographics to behavior—enable you to deliver content that speaks directly to individual preferences, enhancing engagement.



5. CRM and survey tools

Comprehensive insights into customer needs and preferences drive effective campaigns. Integration with Customer Relationship Management (CRM) systems and survey tools equips you with in-depth knowledge, enabling you to create lead-nurturing emails that truly resonate.

6. Compliance with regulations

Compliance with email marketing regulations is non-negotiable. A reliable ESP ensures your campaigns adhere to standards like GDPR and CAN-SPAM, safeguarding your brand's reputation and protecting you from potential legal entanglements.

Each of these factors is important to effectively execute your email marketing strategy. By thoughtfully considering these features when choosing an email provider, you're setting the stage for enhanced efficiency, engagement, and success.
