The Top 21 Best Email Marketing Services in 2023

Email marketing continues to be a critical strategy for marketing (and sales teams) across an array of industries and business types, and an email marketing platform is one of the first additions to a marketer's tool belt — and for good reason.

Email marketing remains a quick and effective way to engage and nurture leads into loyal customers. It's also extremely cost-effective — some studies show an ROI of $40 for every $1 spent. Simply, email marketing services exist to make the process of email marketing simpler — they have features and capabilities that enhance and streamline email communication (among other things) to help you identify qualified leads, nurture those leads, and close more deals.

Many of these tools not only offer email support, but they may also help you organize and store contact information in your CRM. But with so many email marketing tools available today, where should you start? We'll answer those questions and more in this guide to email marketing services — let's dive in.

Why is an email marketing service important?

Today, email marketing services continue to be an integral, strategic tool for businesses of all sizes across all industries — they help businesses build strong relationships with prospects and customers all while moving them through the buyer's journey and maintaining strong communication throughout.

Not to mention, as ESPs continue to develop, features like A/B Testing, automation, and personalization have made the tools even more valuable to a marketer looking to engage with an increasingly fragmented audience.

What to Look for in an Email Marketing Service

1. Security: Email addresses are personal and sensitive customer data that you're responsible for protecting. Your email marketing service provider should have robust precautions in place and use best practices to protect this data like DMARC email authentication standards.
2. Ease of Use: If you're using email marketing as a strategy to nurture and convert customers, it should be easy to spin up an email and send it to your audience. Look for drag-and-drop features and templated workflows in your email tool.
3. Audience Segmentation: Personalization is a key component of a successful email marketing strategy, and for this, you'll need audience segmentation included in the tool you choose.
4. Automation: Automated workflows, triggered sends, and scheduled emails are all parts of email marketing automation that come in handy for small and large teams alike. Look for these automated features when choosing an email marketing service.
5. Third-Party Integrations: Odds are, you and your team aren't handling your marketing tasks manually. A great email marketing provider will be able to integrate with many of the other tools you use, especially a CRM.
6. Data Analytics: Keep track of open rates, bounce backs, and CTR with data analytics weaved right into your next email marketing tool
7. Customer Support: Even after learning your new email marketing service tool through and through, you'll need help from the support team at some point. Make sure the provider you choose has a helpful and accessible customer support team that you can lean on when you need help.

Now let's look at some of the best email marketing services today — one of which you might choose to implement at your company. (And psst: If you need help writing your emails once you've found the right provider, this video can help you do so seamlessly.) 

For each of the following services, we've listed notable features as well as pricing details but we still recommend reviewing the service's product and pricing pages for greater detail.

1. HubSpot Email Marketing Software

Best for email marketing that’s powered by CRM data.

HubSpot's free email marketing software is secure and easy to use, has an extremely high deliverability rate, and includes all the bells and whistles you'd expect to see within an ESP.

HubSpot Email Marketing Software Features

When creating an email, you can pick from one of many drag-and-drop email templates, or you can craft a custom template tailored to your brand. Once you've got your template, incorporating content is simple and intuitive.

You can also personalize and preview your emails for different recipients based on device type, country, or list inclusion — or use a simple personalization token to ensure that each email includes content that's specific to each recipient.

When it comes time to send an email, using the smart send feature will ensure recipients receive your messages at an ideal time. Additionally, you can run A/B tests to compare different versions of an email to understand which one resonates the most with your audience. You also won't have to worry about deliverability — HubSpot maintains a 99% deliverability rate across the network for all marketing email sends.

Outside of the email marketing functionality, HubSpot offers a wide range of reports on your email’s performance, letting you judge what's resonating with your audience so you can optimize your strategy accordingly.

In their email marketing software guide, Venture Harbour put it like this: "By connecting the dots between your marketing, website, and sales activity, HubSpot is able to attribute which campaigns influence your sales — which means you can invest more in what works and less in what doesn't."

For instance, you can report on something as broad as your overall email performance in Q1 or you get granular and see how one particular lead is interacting with your emails.

You can also leverage tools like HubSpot's Email Writer and Campaign Assistant to create email marketing campaigns.

Lastly, HubSpot's automation platform makes it easy to scale your email marketing strategy, which will help you quickly turn leads into loyal customers.
