What is email marketing software?

Email marketing software is a service-based technology that can help you grow your email subscribers, maintain communication with those subscribers, and increase sales.

In a nutshell, it's a tool for reaching people where they go every day: their inbox. 

The inbox is a fantastic opportunity for your company to send a warm welcome, notify a customer of holiday discounts, and remind them they forgot a few items in their shopping cart. 

But these tools let you do so much more than just send welcome emails. You can do A/B testing to see what type of emails your customers prefer, segregate customers into different subgroups, gain insight into where your subscribers are located in the world, and so much more. 

Long story short, you can move your potential customers through a buyer's journey and maintain strong communication throughout.

At the end of the day, these cost-effective tools remind you that there's a human behind every inbox and then offer you every tool you need to interact with those people in a human way.

Here's a more detailed exploration of some of the top features: 

Building an email newsletter

If a website is a window to your business, the same can be said for your email newsletter. The best email marketing tools let you design an eye-catching and unique newsletter by importing your own HTML, starting from scratch, or using a predesigned template. Most of these tools have a drag-and-drop editor, making it exceptionally easy to create an attractive email newsletter that you can personalize to fit your brand's design.


The best email marketing services let you set up powerful automation flows. You'll be able to provide an exceptional customer experience by sending out targeted email sequences or perfectly-timed campaigns based on your subscribers' behavior. For example, you can create an automated abandoned cart email sequence that will encourage customers to go back to your online store and complete their purchase and send welcome emails for new subscribers or thank-you emails for recent purchases.

Analytics and Reports

With powerful analytics and reports tools, you'll be able to get detailed insights into how your subscribers are behaving. 

You'll be able to get the answer to questions like:

  • How many subscribers open your emails?

  • Do they delete or forward your emails?

  • How long do they stay on the email page to read the content?

  • Are they clicking on any links inside the email?

  • Is your demographic male or female? 

All of that information will ultimately help you optimize your campaigns and improve your results over time.

Contact segmentation

Sending out bulk emails won't increase your sales. But by using a feature like contact segmentation, you'll manage to divide your subscribers into separate segments or groups and send them personalized emails that will keep them engaged. 

For example, an email marketing tool with an advanced segregation feature will allow you to create subscribers groups based on:

  • Geolocation.

  • Autoresponder engagement.

  • Click-through.

  • Purchase behavior.

  • Browser used.

The possibilities are basically endless.


Using an email marketing software as the only tool in your toolbox might bring in some value. However, when you connect your email marketing software with your CRM, blog, or an eCommerce system, what you'll get is a complete marketing solution that drives revenue.

drip email marketing software

Many tools would say that they have the best email automation features for creating effective drip campaigns, but no tool does it better than Drip. After all, it has the word drip in its name. 

The software's features are divided into four categories: customer data, personalization, engagement, and optimization.

Drip's advanced segmentation features let you understand how your customers interact with your business and create insightful profiles based on that data.

Once your database is created, there are plenty of features for increasing customer engagement. For example, the platform's behavior-based automation leverages artificial intelligence to help you engage with customers at the right moment. You can configure the platform to send a reminder email if a customer abandons their cart or a promotional email on a customer's birthday.  

The platform's optimization features enable you to get the most out of your email marketing strategy. For example, with the automatic revenue attribution feature, you can gain insight into which campaigns are successful and which ones are a failure.

The good news is that you can test every customer-focused feature for free for 14 days. The other news is that if you want to continue using the service past those 14 days, you'll have to subscribe to a paid plan. Drip's paid plans start at $19 per month for an account of between 1 and up to 500 customers with unlimited emails. For between 500 and 2,000 customers in your account, you'll pay $29 each month.

Many would agree that the most challenging part of an email marketing campaign is collecting potential customers' email addresses. 

If you're struggling with growing your subscribers' list, then take a look at OptinMonster.

OptinMonster prides itself on being the best conversion and lead generation tool on the market today.

Forget about "traditional" centered lightbox popups. OptinMonster lets you create a range of different types of opt-ins/offers, including popup, floating bar, fullscreen, inline, slide-in, and interactive. The most exciting of the bunch is probably the interactive popup that appears as a "Spin to win" wheel. The popup is quite practical for online stores because it lets you reward customers with discount codes.

Another one of OptinMonster's strong sides is its detailed targeting and trigger rules. In other words, you can configure where your popups appear, who sees them, and when they display. For example, you can trigger your "Spin to win" wheel to popup when a customer is inactive on your site or after the user has scrolled X% of the page. On the other hand, the targeting feature lets you target customers based on the visitor's location, the type of device they're using to access your site, whether they're returning customers, and more. 

OptinMonster gives you all the tools you need to add personalization to your email campaigns. For instance, if a customer has already converted on your "How to Decorate Your Home" blog, you could send them a link to your "How to Decorate Your Balcony" blog that connects with that first offer.

There are four pricing plans. The cheapest one is priced at $9/month and contains all the essential tools you'll need to get more leads from your existing traffic. Their most popular plan costs $29/month and contains everything you need to get huge results, fast.

You can further personalize your emails based on a subscriber's information, such as name, membership, interests, and more to send them the emails with the most relevant subject lines, most dynamic content, clickable links, and compelling call-to-action. 

Through detailed analytics, you can gain insight into which emails are performing well and which aren't, and optimize the less successful ones using a feature like A/B testing. 

Workflows are another great feature the app offers, letting you create three different types: when a contact enrolls or joins a list, on a specific calendar date or holiday, or when a trial expires or renews. You can even have multiple workflows running simultaneously.

The Popups feature is a useful way to grow your subscriber's email list. There's a range of designs you can use that can be activated at different points in a customer's journey, for example: upon first visiting your store, after clicking on specific items, or when they're about to leave your store.

Key takeaways

According to some estimations, a marketer who uses marketing automation software can complete a 50-person job. Can you imagine? A single piece of software completing the job of 50 pairs of hands! And brains. A piece of software building unforgettable customer journeys, sending personalized messages, capturing leads, and nurturing customers, day in, day out. 

The email service providers (or ESP) we saw in this post are the best of the bunch. Some of them are more geared towards smaller businesses, while others are more suitable for larger enterprises. There are many others that we didn't get to mention, like:

  • ConvertKit

  • Salesforce Pardot

  • GetResponse

  • Moosend

  • SendInBlue

  • MailerLite

  • Aweber

During the evaluation process, you'll have many things to consider, starting with your budget. Keep in mind that as you're growing your subscribers' list, the paid plans' price will go up as well. Word of the wise: make sure you're successfully monetizing your email campaigns. 

Moreover, think about whether you would prefer the tool to have an easy-to-use drag-and-drop editor, or will you prefer an extensive set of pre-made email templates? Would you prefer a tool with a more basic set of features, or will you be needing more advanced features like A/B testing, split automation, and spam testing? 

Hopefully, we've included something for everyone on the list. Whether you're starting your first online store, switching providers, or looking for a full-service CRM, we'll sleep better at night knowing we helped you make the right choice.
