Choosing the right marketing automation platform can transform the way you engage customers. From streamlining campaigns to delivering personalized messages across multiple channels, the right tools help you save time, boost conversions, and grow revenue.

Marketing automation platforms can help you: 

  • Send contextual messages to customers on their preferred channels using various triggers and automation rules. 
  • Set up and automate complex flows or entire campaigns across a range of touchpoints, like email, SMS, WhatsApp, push notifications, and more.
  • Save time and effort by streamlining routine marketing tasks around campaign management, data collection, and lead nurturing.

While older marketing automation software tools were built primarily for email, today the scope of the automation category and the needs of marketers have expanded dramatically. As a result:

  • There’s no “one-size-fits-all” when it comes to automation platforms. It all depends on your business needs, marketing workflow, and the channels you’re using.
  • It can be difficult to compare automation solutions due to the many subtle differences between them. This problem is further compounded by the fact that many lists lump wildly different solutions under the automation category.

To help you find the right solution for your business, we’ve taken the top 13 marketing automation platforms and organized them into three categories:

  1. Marketing clouds and cross-channel automation platforms. These can be all-in-one automation solutions for teams that already have a few successful marketing channels and a relatively complex marketing operation. They can help you automate a ton of tasks around data collection, cross-channel campaign orchestration, personalization, lead management, segmentation, A/B testing, and much more.
  2. Marketing automation platforms focused on email and SMS. These solutions enable small and mid-sized brands to automate campaigns across the two most widely-used channels. While not as versatile as the platforms in the first category, some of these tools can also automate messages and campaigns on other channels, like WhatsApp, web push notifications, and social media.
  3. Email-only marketing automation platforms. These are by far the simplest automation platforms on this list. They have everything needed to get started with email marketing automation, without all the advanced, cross-channel functionality that most small businesses and individual creators don’t need anyway.

We’ll start the list with Insider One—our comprehensive personalization and automation solution for websites and mobile apps, as well as channels like email, SMS, push notifications, and WhatsApp.

Insider One can help you create, personalize, and automate simple flows and complex marketing campaigns across all customer touchpoints. Visit our website or schedule a demo with our team to learn more.

Marketing clouds and cross-channel automation platforms

These platforms are great for automating campaigns and synchronizing your efforts across a wide range of channels like:

  • SMS.
  • Email.
  • WhatsApp.
  • Push notifications.
  • Social media (for running retargeting ads on Facebook or Instagram, for example)

They also have powerful personalization capabilities for tailoring different elements of your campaigns, like content, product recommendations, and send times, to each individual customer. 

The broad channel support and extensive personalization features make these platforms a great choice for advanced marketers at enterprise and mid-sized companies looking to:

  • Unify their marketing stack, streamline workflows, and maximize their marketing budget by using one platform to create, manage, and automate campaigns across all channels (instead of five or six channel-specific solutions).
  • Expand to complex use cases like omnichannel automation, customer experience personalization, and data aggregation. 
  • Explore new channels that their current automation solution doesn’t support.

Insider One

Insider One brings together the most extensive set of personalization and automation capabilities for websites and mobile apps, as well as for channels like email, SMS, push notifications, and WhatsApp.

Our platform has been ranked among the top solutions in various categories, including:

Thanks to the wide range of capabilities and native channels, over 1200 brands like Adidas, Vodafone, and Lexus use Insider One for various use cases like:

  • Automating flows and campaigns across all customer touchpoints from a single place using Architect—our cross-channel customer journey builder.  
  • Maximizing their marketing efforts and budget by consolidating their stack, instead of using a bunch of different automation and personalization tools for each channel.
  • Increasing engagement, conversions, and revenue by automatically personalizing every customer touchpoint—including their websites, mobile apps, email, SMS, WhatsApp, push notifications, and more.
  • Getting an accurate, 360-degree view of all their customers’ interactions, behaviors, and preferences by consolidating their data into our Actionable Customer Data Platform (CDP).

In the next sections, you’ll learn about the key benefits of using Insider One to automate your cross-channel campaigns and other parts of your workflow.

Enable true cross-channel automation

Insider One supports over 12 marketing channels natively—including websites, mobile apps, SMS, WhatsApp, email, push notifications, and others shown in the screenshot below.

Because these channels are built into our platform, you don’t need a third-party solution to automate messages or campaigns on them. This can help you drastically simplify your marketing stack, streamline operations, and maximize your marketing budget.

However, Insider One doesn’t just let you reach customers on these channels. With our platform, you can synchronize your efforts across all touchpoints to create a truly consistent experience for your customers. 

For example, say a customer showed interest in a certain product category and price range on your site. You can use that information to: 

  • Automatically send them a web push notification with relevant product suggestions. 
  • Set up an automated email campaign for customers who didn’t buy after seeing the push notification.
  • Expand the journey to other channels by automatically sending messages with discount codes on channels like SMS or WhatsApp.

The key here is that each subsequent message can take into account how the customer reacted to the previous one. This cross-channel marketing approach ensures your messages and branding are always consistent, which produces higher engagement and more conversions.

This is possible thanks to Insider One’s ability to consolidate all your customer data in our CDP (which comes free with our platform) to reveal each user’s:

  • Purchase history
  • Channel reachability.
  • Preferred channels and times to interact with your brand.
  • Predicted behaviors (e.g., likelihood to purchase or churn).
  • All interactions with your brand across your website, mobile app, and external communication channels.

For example, the screenshot below shows a unified customer profile in Insider One’s CDP that contains all these insights.

However, if you already have your data consolidated in another CDP like Segment or Amplitude, Insider One can simply connect to it. That way, our platform can use the data to help you build and automate high-converting campaigns, without you having to stop using your current CDP. 

In fact, Insider One’s flexibility allows it to connect and automatically exchange data with any online or offline solutions you might be using—including customer relationship management systems (CRMs), content management systems (CMSs), point-of-sale (POS) devices, analytics software, customer service platforms, APIs, legacy systems, and much more.

Remember, when choosing a tool for your business, you must consider several factors, such as industry and the size of your business. For example, if you are in the real estate industry, investing in a CRM for realtors may be a great starting point while also considering other aspects of your business to ensure your chosen tool is the ideal fit.

Trigger automations after specific actions, periods of time, and much more

Insider One makes it easy to build automated flows and campaigns for all sorts of use cases. For example, you can use our solution to create:

  • Standard email purchase confirmation and order update flows.
  • Cross-sell and upsell campaigns on messaging channels like SMS or WhatsApp.
  • Cart or browser abandonment automations via cost-effective web push notifications. Note: Vodafone used on-site cart reminders to increase conversion rates by 159%.
  • Complex cross-channel marketing campaigns that are personalized to each customer’s preferences.

You can set up these and other automations with our journey orchestration tool called Architect. 

This tool lets you build automated flows and campaigns (called Journeys) using a simple drag-and-drop editor. Each journey can be triggered by:

  • An event, like a customer opening a page, adding items to their cart, completing a purchase, passing by your physical store, or any other action.
  • An attribute change, like a customer moving up to a higher loyalty timer after spending over a certain amount with your brand.
  • A dynamic date, which is a great option for celebrating customer milestones (like birthdays or anniversaries) or running replenishment campaigns for products that are bought at a regular schedule.
  • A price drop or restocking of an item that customers are interested in.
  • And more. 

Once you choose the trigger, you can decide which segments should be included in the journey. Here, Insider One’s advanced segmentation helps you hone in on the right audiences for each flow or campaign.

You can use three types of audiences to build highly-targeted campaigns:

  1. Standard audiences: These include 120+ attributes, like locations, devices, operating systems, demographics, behaviors, preferences, and more. 
  2. Predefined audiences: These are automatically created audiences who abandoned their carts (or a product page), made a purchase over a specific period of time, interacted with your brand on a specific channel, and others shown below.

AI-powered predictive audiences: This option lets you utilize our AI-powered intent engine to target users based on their discount affinity, projected spending, likelihood of purchase or churn, customer lifecycle status, and much more.

With your initial trigger and segments in place, you can freely choose how each journey unfolds. For example, you can select which channels Insider One uses to contact customers from the extensive list shown below.

Note: The “Call an API” option lets you extend your reach even further to systems like Intercom or Zendesk, for example.

You also have granular control over exactly when initial and follow-up messages get sent with the “Wait” and “Check” elements:

  • The “Wait” element lets you instruct Insider One to wait for a specific amount of time, until a time slot, for an event, or for an attribute. For example, you can have Insider One wait until a customer visits your website without purchasing before triggering a promotional email with your latest discounts.

The “Check” element lets Insider One see if customers are available on a specific channel (or have previously interacted with your brand on it) or check any other condition before proceeding. For example, you can have Insider One check whether customers have opened a specific email from your previous campaign. Those who have can receive another message on the same channel, while others can be contacted via SMS or WhatsApp, for example.

For more details, tactics, and examples of Architect in action, check out the articles below:

For a real-life example, you can refer to our case study with beauty and cosmetics brand Clarins. They used Architect to deliver relevant and personalized experiences on the channels their customers use, leading to a 45% increase in lead capture, a 4% uplift in conversion rates, and a 30x ROI in 12 weeks of using Insider.

How to generate more engagement and revenue with AI-powered automations

Using multiple channels to reach customers is the standard today. And while that provides lots of opportunities for brands, it also raises two big questions with regards building an effective cross-channel marketing strategy:

  1. Which channel should you use to contact customers in a specific flow or campaign? For instance, imagine your brand uses email, SMS, WhatsApp, and push notifications regularly. It can be nearly impossible to know which of these touchpoints is the best choice for each customer and use case.
  2. When should each message be triggered? Some users may prefer to interact with your brand earlier in the day, while others may want to do so after work (or exclusively on the weekends). There’s no universally accepted time to send a campaign message, so brands often struggle to time their messages to each user’s preferences.

The traditional approach here would be to A/B test different channels and send times. And while that can certainly provide good results, it often takes lots of time, effort, and resources to find the right mix of channels and send times that work for each segment.

Insider One has two AI-powered capabilities that can help you avoid this issue altogether:

  1. Next-Best Channel Predictions: This feature analyzes each customer’s past behaviors and automatically uses their preferred channels. All you have to do is enable the feature when building a journey and select your channels.

Send-Time Optimization (STO): Like the previous feature, this one also analyzes each customer’s behavioral patterns to determine the best time to send each message. You can enable STO when building messages for each individual channel like email, SMS, WhatsApp, and push notifications.

Make smart decisions with built-in A/B testing

Besides relying on Insider One’s AI-powered capabilities to optimize your journeys, you can also run A/B tests to compare any variables you like—from subject lines, images, and body copy to different channels (e.g., email vs. SMS) and entire flows. 

As you can see below, setting up even complex A/B tests is quick and easy with the drag-and-drop editor.

Additionally, Insider One’s A/B Testing Winner-Autoselection feature can save you lots of time and effort when determining your test’s results. 

This feature automatically detects and directs users to the winning path in your A/B tests using our machine learning algorithms. The selection is based on two criteria you select beforehand: 

  1. A winning metric for the test, like open rate, conversion rate, revenue, and so on.
  2. Calculation duration, which is the time over which the winning metric is calculated and the winning path is announced (e.g., 30, 60, or 90 days).

With this feature enabled, you don’t have to worry about manually analyzing each test and adjusting your automations based on the results. 

You can speed up your tests (and campaign creation in general) by also using our ChatGPT-powered AI capabilities to automatically generate engaging copy for your messages, including subject lines, body text, and more.

Analyze your automation strategy with advanced analytics

Once it’s set up, Insider One will give you a detailed overview of your entire user base, including:

  • Number of known and unknown users.
  • Channel reachability.
  • And other key metrics.

From here, you can start digging deeper into your analytics data by focusing on specific segments, channels, or journeys. 

For example, after launching an automated campaign, you can analyze its results in real-time right in the journey builder to see how many people entered each step, where drop-offs occur, and which channels produced the best results.

There’s even a more granular view of all your automated journeys (or just select ones) in the dedicated Architect analytics dashboard.

You also can drill down into specific channels and analyze their individual open rates, click-through rates (CTR), conversion rates, and other essential metrics.

Lastly, you can build custom dashboards for different teams inside your organization. 

For example, you can have detailed dashboards for marketers interested in metrics like open rates, CTR, and channel reachability and simpler ones for stakeholders and C-level executives who are primarily focused on revenue and acquisition costs.

Start quickly with a plethora of proven automation templates and an experienced support team

Besides picking channels and send times, we know that getting started is the biggest challenge when it comes to cross-channel automation, especially for large companies.

There are just tons of factors to consider and challenges to overcome—from disconnected systems to complicated workflows, difficult integrations, and the learning curve that comes with using a new system.

That’s why we’ve made sure that Insider One customers can get started and see a return on their investment as fast as possible. There are two key components here:

  1. Our extensive template library: You can find a pre-built, customizable automation template for pretty much any channel (or combination of channels), use case, and industry. For example, we have templates for creating better post-purchase experiences, welcoming new customers with personalized messages, gathering customer feedback, reducing cart abandonments, driving replenishment orders, and much more.
  2. Our experienced customer support team: Our team can help you set up Insider One (with no extra setup cost), as well as create and implement the right automation tactics, based on your current analytics data. Also, if you already have automations set up in other tools, our team will migrate them to Insider One, so you don’t have to build them again.

Overall, Insider One’s combination of extensive templates, trainings, and high-quality support is essential to many of our customers.

“Great support from the Insider One team; trainings, onboarding and on-going technical and strategic support. Product works well, haven’t found any bugs and there is a lot to offer to really power on-site optimisations, run campaigns, conduct A/B testing and plan user journeys out.

Why should you Combine automation and personalization: To deliver tailored content, messaging, and product recommendations on autopilot

Insider One isn’t just a solution for automating flows and cross-channel campaigns. Our platform also has extremely powerful personalization capabilities that let you individualize each customer’s experience based on their needs, interests, and preferences.

For example, Insider One lets you automatically tailor every element of your site or app to each customer browsing it, including:

  • Categories: Adidas used our Category Optimizer tool to rearrange their site’s mobile menu based on each customer’s browsing history, resulting in a 50.3% increase in their mobile conversion rate.
  • Product recommendations: Philips used our AI-powered Smart Recommender to show relevant product recommendations to users on product pages, leading to a conversion rate uplift of 40.11% on their mobile site and over €20,000 of incremental revenue.

When it comes to product recommendations, you can leave the process completely in the hands of our algorithms by selecting a user-based recommendation strategy. This is a great way to easily increase engagement, conversions, and revenue, as our platform automatically serves relevant recommendations to each user.

You can also choose from a wide range of other recommendation algorithms—like most popular items, top sellers, viewed together, purchased together, and so on—and tweak them based on your preferences.

Insider One also makes it easy to scale personalizations across all external touchpoints, like:

  • SMS.
  • Email.
  • LINE.
  • WhatsApp.
  • Facebook Messenger.
  • Push notifications.
  • And much more.

Our platform can deliver targeted messaging, content, and product recommendations with each message you send on these channels. 

Combining Insider One’s personalization capabilities with its powerful automation features, like Next-Best Channel Predictions and STO, lets you take your cross-channel marketing to the next level and automatically deliver truly individualized experiences.

Note: Just because Insider One supports so many channels doesn’t mean you have to use all of them from the start (or at all). Many of our customers start with just one or two channels, like on-site and email, and then expand to other touchpoints and use cases over time.
