The Best Email Marketing Service Providers for Ecommerce

Email has certainly evolved over time, but the one thing that hasn’t changed is that it is the core of every Ecommerce business. 

From basic newsletter blasting and automations to more advanced AI-powered marketing and personalization, email marketing is the central channel.

By 2022 over 347.3 billion daily emails will be sent per day throughout the world [Statista, 2020]. Email also continues to have a massive return on investment, where $1 spent on email marketing can generate an average return of $42 [DMA, 2019].

It’s no surprise that with email marketing on the rise, dozens of Email Service Providers (ESP) have sprung up to serve the market needs, typically with a unique differentiator. 

The one thing that I think is most important for you, is that it was built with Ecommerce in mind, because that makes your automations and campaigns that much more powerful, and easy to implement. For a full guide on what email marketing automation you need, check out this article by ShopPad.

And, to add to the convolution of the industry, it's worth mentioning there are other types of tools, such as Customer Relationship Management (CRMs) and Customer Data Platforms (CDPs) that may encompass email marketing in their tools.

As a store owner, your time and resources are limited. And choosing the right email marketing provider is a big decision. You should expect to dedicate at least 5 hours to researching, vetting, demo’ing, and selecting the right provider for you. And I’ve seen this go up to 40+ hours of time for larger Ecommerce merchants.

To help cut down that time, and get you closer to the end goal - making money with email marketing - we’re sharing our list of best email marketing service providers specifically for Ecommerce businesses. 

Starting store vs Mid-Market vs Enterprise

We breakdown better fit solutions based on the size of your store from a revenue standpoint, as your revenue will indicate about how many contacts you have, and how many hours of resource time you can dedicate to the tool.

Your needs change as you grow… Whether you’re a brand new store - sub $1 mil revenue, in growth mode, mid-market ($5-$100 mil), or enterprise level. 

A few key differences I’ve noticed are:

  • Small stores just need anything and they need it for cheap.
  • Mid-stage stores are looking more towards optimization, squeezing the juice from their more successful campaigns, growing the list, and keeping engagement high. Often they benefit from native integrations, such as with loyalty tools or other channel tools (SMS, Messenger, etc.)
  • Enterprise stores typically need integrations, the data needs to be piped into lots of places, their working on segmenting users and really want to use the CRM or CDP aspects to the fullest - meaning they want to analyze their customers and use the strength of a large list to segment, automate, and send. Smart segments and Artificial Intelligence / Machine Learning (AI/ML) become important here.

At all stages of your store, the bottom line with email is revenue, whether that is in the form of increasing:

  • Average order value (AOV)
  • Lifetime value (LTV)
  • Or conversion rate

CRM vs. CDP vs. ESP: Which is What?

With so many different tools (and acronyms), choosing one can be a daunting and difficult task. 

Although each platform offers different functionalities, the main goal is to choose one that integrates seamlessly with your Ecommerce platform to pull metrics such as purchase data, customer tags, as well as shopping behavior. These metrics provide valuable insight to your business at large and will ultimately determine the performance and growth of your email marketing campaigns.

Let’s briefly explore the difference between these three technologies.

What is a Customer Relationship Management (CRM)?

A CRM is used to track new leads, sales, manage contacts, and support and sales teams. By effectively managing all communication and interactions with customers and potential customers throughout their life cycle, businesses are able to streamline their processes, as well as improve profitability.

The real value in a CRM is in the flexibility of the data you can bring in for each contact. CRMs make it easier to manipulate customer data, create automations and segments, and view customer journey’s.

In all honesty, most ESPs are CRMs at some level, since you can see the email address and some basic customer information. You could even say that Shopify has a CRM in their “customers” tab in the backend. But you’ll notice limitations with the simpler ESPs at some point and will generally want to sacrifice some ease of use for customization, as you grow.

What is a Customer Data Platform (CDP)?

A CDP creates unified customer profiles with data gathered across online and offline channels. By collecting primary data, they can streamline customer experiences and messaging across platforms, as well as understand customer behavior. 

The main difference here is that this may be used across product and marketing, and typically requires a network of integrations and possibly manual APIs.

Put more simply, you could say a CDP is a more advanced CRM, but is typically removed from the act of marketing - taking action with the information.

CDPs are more commonly used by enterprise retail and Ecommerce businesses because their capabilities of gathering consumer data points across multiple channels / sources helps unify what is often a fragmented view of the customer profile. However, a CDP does not convert this data automatically into marketing campaigns. 

What is an Email Service Provider (ESP)?

An ESP creates marketing campaigns in the forms of emails. These providers offer email design tools for newsletters and automations, as well as segmentation, personalization, triggers, email optimization tools and more.

Although CRMs and CDPs are nice-to-haves for exploring customer touchpoints, they are not needed for every Ecommerce business. But you absolutely must have an ESP that sends emails, as well as starts the most basic version of your CRM by collecting and storing customer data.


We divided this article into 4 sections based on stage of your store:

The Best Email Service Providers for Small Ecommerce Stores

So you’ve just started out, maybe you are on Shopify, and you’re looking for something that does the trick, but will keep your app costs relatively low.

As a small business, you’re going to need a tool that provides contact management, a strong email editor and automated email responders to keep in touch with your growing database.

Although there are dozens of ESPs for startups and small businesses, we wanted to focus on four that also excelled at providing:

  • An easy interface for first time users or novice players
  • Pre-built templates and campaigns geared towards Ecommerce
  • Ex. Abandon cart sequence
  • Seamless integration with your Ecommerce platform

I’m sure you have too many things to do and not enough time. Between wearing the email marketing hat, you’re also juggling logistics, customer service, and supply chain management.

Opting for a tool that can be easily set up within a few hours with as little distraction as possible will be key here. 

Let’s take a look at four starting tools that will save you time and come in at the low end of the market ( keeping your costs low):

And I do also believe many of the tools in the “scale” section, a little bit lower, could be a great fit for you too. They are simply in a different section because they offer a bit more “upper mobility” than these three.


In-App Email Marketing Platform

As a small business, you might not have time or the patience to log in into various apps and keep multiple passwords. Seguno is made with the simple small business in mind, but also has a good deal of automation components, and dynamic discount codes. If you need basic functionality and don’t have the time to invest heavily in email, this may be a good fit.


  • Built directly into the Shopify app and can be managed from desktop or mobile
  • One-click automations
  • Unique coupon codes
  • Basic segmentation and reporting


Seguno is free for businesses who have 250 or less subscribers, while its month-to-month plan begins at $10USD per month for up to 1000 subscribers. Offers billing through Shopify. 


All-in-One Marketing Platform

As a leader in the email marketing provider market, Mailchimp was once the most popular app for email marketing.

In March 2019, Mailchimp announced that it had removed its Mailchimp for Shopify integration from Shopify’s marketplace. With hundreds of Shopify users already using the app, many began migrating their lists to alternative providers. Others relied on third-party apps like Zapier, and ShopSync to link both apps together.

Mailchimp continues to be a contender for the Ecommerce community including Shopify for a variety of reasons. 


  • Flexible template library
  • User-friendly drag and drop builder
  • Advanced reporting and analytics
  • Small business marketing tools like snail postcards, landing pages, and social media advertising.

Opting for a tool that provides an all-in-one marketing platform can lend small businesses the opportunity to grow regardless of their resources or budget.


Mailchimp is free for up to 2,000 contacts and includes segmentation, behavioral retargeting, as well as 7 different marketing channels like Facebook and Instagram advertising, postcards, social posting and more.

For a detailed explanation, check out this extremely detailed article from SendX called "MailChimp Pricing".

This tool literally writes your emails for you, using your product feed, images, brand voice, and a few questions you answer for them. Great for a small store or small team that perhaps isn't so focused or experienced in email marketing.


  • Abandon Cart Sequences automatically created for you.
  • Suggestions for new campaigns or sequences.
  • Advanced store profiling.
  • Automatic campaign A/B split testing.
  • Advanced segmentation


Starts at $38/month (billed annually, or $45/month billed monthly), for 1,000 contacts, and going up from there. Right now, when you sign up, you can get an extended 60 day free trial (subject to change in the future, check their site for any changes/updates).

The Best Email Service Providers to Scale Your Ecommerce Store

As your business scales and your email marketing list grows, your data will understandably become more complex, you’re going to want to start segmenting, and you may need some advanced automation. 

Opting for a platform that provides powerful segmentation will be key here, as you’ll begin to build unique newsletters and automations based on your audience and behavioral data.

Here are some key features to look out for when choosing the best ESP to scale your business:

  • Simple migration services or support in order to transition from one ESP to another
  • Dynamic and advanced segmentation that is updated automatically 
  • Predictive analytics and advanced reporting
  • Omni-channel marketing functionalities or integrations

CM Commerce

Platform for Email and Social Proof

CM Commerce’s Starter plan begins at $9 per month to send 5,000 emails to 500 people, but does not offer browse abandonment email, social proof or integration with Facebook ads at that price point. For lists of 501-1000 subscribers, businesses can sign up for their Growth plan at $49 per month for unlimited emails, as well as all core features such as social proof and deep integrations.


AI-Powered Omni-Channel Platform

AiTrillion is unique because it really does combine nearly all aspects of Ecommerce tools into one. We’re talking loyalty, automation, pop-ups, chatbots, product recommendation tools, and AI tools.

  • Loyalty rewards programs
  • Product reviews

The Best Email Service Providers for Mid-Market to Enterprise Ecommerce Stores

If you’re looking for an email provider that meets mid-market to enterprise needs, you’ll probably be migrating from an existing ESP that you’ve outgrown.

With complex management, logistics and customer data, you’ll need a platform that integrates seamlessly with your ecommerce provider and perhaps your CRM and other automated systems. 

You’ll also need a tool that uses advanced segmentation, artificial intelligence, machine learning and predictive analytics to better digest data across multiple channels and develop new, cohesive strategies.

Some other key features to look out for:

  • Dynamic content and personalization
  • Advanced reporting and insights
  • Advanced A/B testing
  • Omni-channel integrations

There are many enterprise competitors that offer the data and support for mid-market and enterprise businesses, but our top 4 are:

Dynamic Yield

End-to-End Personalization Platform 

Built for enterprise businesses such as Urban Outfitters and Ikea, Dynamic Yield offers an all-in-one platform for personalizing all web, mobile, app, email and advertising not only for B2C businesses, but also B2B, Gaming, Media, Travel and more.

The Best Email Service Providers for Abandon Cart Recovery and Customer Retention

Outside of a dedicated ESP there are a few other tools worth mentioning that solve specific problems. Although several ESPs can do similar functionalities, these tools are worth a mention because they are dedicated to this one aspect of the funnel.

  • Privy - Pop up tool with important abandon cart functionality.
  • Cartstack - focused 100% on abandon cart/checkout.
  • Spently - Optimize your notification emails.


Conversion Rate Optimization / Email Collection

Originally an on-site popup service, Privy has developed new email marketing capabilities as well as SMS marketing features that help businesses increase customer retention. The reason this is important is because they can increase abandon cart email sends by up to 500% (more sends = more $$$) - it’s the crucial integration of having your pop up tool and your email automation tool be one in the same, because without that, like if you send email addresses from a pop-up tool to your ESP, you lose some tracking components, and therefore lose opportunity.


  • Purchase-based automations such as Autoresponders, Abandoned Carts and Order Follow Ups
  • On-site customizable popup forms
  • Dynamic coupon creation with Shopify and Bigcommerce


Privy offers a full email marketing suite for up to 1000 contacts and access to its pop-up displays for up to 3,000 page views per month at $10 per month. It also offers SMS marketing for up to 100 contacts at $10 per month.


Website Abandonment Platform

If you would like to focus exclusively on recovering lost Ecommerce sales outside of an ESP, CartStack can help. 


  • Exit intent and delayed pop-up displays
  • Abandoned cart and browse abandonment email campaigns.
  • “Send my cart” email campaigns
  • Push notification sequences
  • Real-time data capture and enriched contact records to easily capture more email addresses and encourage conversions.


CartStack offers a free trial until you recover $1000 from their app. Once recovered, CartStack’s plans are built on monthly orders. For a Pro plan that allows for up to 100 orders or less per month with browse abandonment email campaigns, exit intents and send my cart campaigns, you’ll pay $49 per month.


Transactional Optimization Platform

If you’re not leveraging Shopify’s existing transactional emails, then you should be.

Spently allows businesses, both small and large, to leverage their notification emails within Shopify with marketing components. Most importantly, you can turn your most important emails, tracking notification emails (among others) into marketing collateral for cross-sells and upsells.


  • Optimize notifications emails with event-based upsells, personalized discounts and referral components
  • Automated follow-up email for Shopify’s native notifications emails
  • Integration with Limespot, Kit, and Sufio

While some ESPs help with creating notification emails, Spently focuses specifically on solving the problem from within Shopify and has robust tracking/analytics for understanding the business impact.


All plans are based on total monthly orders. 

For Shopify businesses who generate 50 orders or less per month, Spently’s Starter plan is completely free. 

For businesses generating 500 orders or less per month, Spently’s Essential Starter plan is $99/month and allows for follow-up emails, personalized discounts, referrals and integration with Limespot, Kit and Sufio (which is not available in the Starter plan).

Pricing goes up from there.

Next Steps

Choosing an email service provider is one of the most important decisions you can make in your business. And as your business grows, your needs grow, which could mean what you started with is no longer the best option for you. 

It’s important to think critically about your business, as you hire new marketing roles, get more creative with your channel marketing strategy, and just generally expand, and think about what kind of data, segmentation, and sequences, will be best for you. 

And remember, having the tool is different than using the tool. If you’re not in your email marketing tool weekly, you’re probably missing key findings, opportunities to optimize, and you may also be clogging your database with useless contacts that should be removed.

After you get email off the ground, or migrate platforms, I strongly consider implementing additional channel tools like Messenger, SMS, and push notifications. And be sure to integrate your email marketing with your loyalty program to build brand advocacy.
