Marketing Automation Software: 8 Best Tools

We overview the software tools involved with marketing automation for your business.


What is marketing automation software?

Marketing automation software is a tool that automatically completes digital marketing activities, including sending targeted messages to your customers and prospects based on their behavior and preferences. It helps marketers acquire new customers, nurture existing relationships, and analyze campaign performance across channels.

The software functions by tracking user actions on your website, app, digital product, email campaigns, and other events. Then, this behavioral data triggers targeted content via email, SMS, push notification, in-app messaging, social, web, and more.

Why use marketing automation software?

Customers want personalized experiences. According to Epsilon, “80% of consumers are more likely to make a purchase when brands offer personalized experiences.”

Through marketing automation, you can automatically tailor marketing messages and send them through the communication channels a customer prefers. Instead of manually triggering campaigns, put the time gained back into your marketing strategy development and leave repetitive tasks to the robots.

5 questions to ask when choosing a marketing automation software

Determine which software is best for your current and future needs by considering the following questions

1. What attributes are most important to you?

Determine which attributes are non-negotiable and what’s simply nice to have based on your use cases and technical capabilities. Next, rank them in order of importance.

Attributes and features to consider include:

  • Ease of implementation

  • Customizability

  • Flexible pricing

  • Analytics and reporting

  • AI assistance

  • Low learning curve

  • Range of integrations

  • Ability to scale as your business grows

As you do your research, you’ll also discover the limitations of each software. Determine how those limitations will affect your marketing activities and decide what trade-offs you’re willing to accept. Talk with the software provider’s team to learn if they plan to address those limitations in their product roadmap.

2. Is it affordable?

Ask your CMO or CFO how much of your marketing budget you can spend on tech or if your company has a separate budget for software across different departments. Be prepared to make a case for your chosen software by illustrating to higher-ups how automation can boost marketing ROI in your business.

3. Is it customizable?

Marketing automation software typically comes with workflow templates, along with a certain level of customizability. Have the software provider demonstrate the customization options to you. Try out the software yourself to see if it lets you connect to the data sources, marketing channels, and analytics tools you regularly use. Try creating workflows and editing the templates on the automation software to gauge how much you can tailor them to your needs.

4. Does it have the customer support you need?

Ask the software’s sales rep specific questions about after-sales support and explain clearly how much support you expect you’ll need. 

For example, many SaaS companies perform user impersonation, where support staff performs actions on behalf of a customer to help them figure out some functionalities. If your software provider does that, make sure to ask how they protect user data and security during impersonation.

If you can, reach out to other businesses that use the software to learn about their after-sales experiences.

5. Does it integrate well with your tech stack?

Choose a marketing automation software that integrates with multiple marketing tools and channels – especially the ones you already use. Examples of tool integrations include:

  • A/B testing

  • CRM

  • Data warehouses

  • Heatmapping

  • Ecommerce platform

  • Email 

  • Live chat

  • Push notifications

  • Sentiment analytics

  • Surveys

  • SMS

  • Social media ads

When you take a product demo, ask to see these integrations in action, so you can see how they will work for your use cases.

How to implement automation marketing into your overall marketing strategy

Before choosing and implementing marketing automation software, assess how it fits into your marketing strategy. Look at the customer channels you use and choose software that integrates with those channels. Consider the types of customer data you collect and select the software that helps you make the most of your data through real-time updates and user-friendly analytics tools. Make sure your automation software is capable of automating workflows that you commonly use in your marketing strategy and of measuring the results.

Design automation workflows to meet concrete goals

List concrete outcomes that you want to achieve with the help of marketing automation and align these outcomes with business and marketing goals. 

Say your company wants to increase profits by 12% this quarter, and your CFO has asked marketing to improve spending efficiency. You look at your analytics reports on social media ad spend and find that you’ve been spending to advertise to customers who have already expressed dissatisfaction with your brand. You can run an automated workflow to cut out those costs. One way to do that is by creating an ad suppression list.

Veronica Beard, a fashion retailer, reduced customer acquisition costs on Facebook by 20% and boosted return on Facebook ad spend by 11% after implementing automated ad suppression workflows. First, it outlined criteria based on customer behavior. Once its CDP identified people who fit the bill, Veronica Beard added them to an ad suppression list. That way, Veronica Beard didn’t have to waste ad spend on unhappy, low-value customers.

Understand what kind of data you need

Automation is based on if-then logic. The input for the “if” part of the equation comes from your customer data and customer segments. In the statement “If a customer has low CLV, then add them to an ad suppression list on Facebook,” “low CLV” is the customer segment. You’d then identify ways to identify a low CLV customer based on the data you have.

Before implementing its ad suppression, Veronica Beard identified what kind of data indicated low CLV. Using product review information from its own review platform, the company created an audience segment of customers who gave a one-star rating. Customers who were added to that segment were then sent to a real-time suppression list on Facebook. The retailer also identified customers who had made two or more orders and returned all of them, and added them to the low CLV segment.

Outline your strategy

At Segment, we advise marketers not to collect all customer data. Instead, have a plan for:

  • What kind of data you’ll track

  • How you’ll collect, safeguard, and keep it clean

  • On which platforms you’ll activate it. 

Collect only the data that will help you achieve your business goals. You can learn more about how to do this in our guide to making a data tracking plan

The same goes for choosing your marketing automation tech stack. Understand what interactions in your customer journey are effective at acquiring, nurturing, and converting leads, as well as engaging and retaining existing customers. Let that knowledge of the customer experience guide you in selecting and refining your marketing tools – not the other way around. Learn more in our series of customer journey mapping articles.
