What I look for in the best marketing automation software
If you’re wondering which marketing automation service offers the best features, here’s what I prioritized while testing and comparing each tool.
- Email marketing and campaign management: Email is a core part of marketing automation, so I look for tools that offer easy email creation with customizable templates and a WYSIWYG editor. A/B testing is essential for optimizing subject lines, content, and CTAs. I also evaluate market segmentation features to target specific customer groups based on behavior, demographics, or purchase history. Dynamic content capabilities are crucial for personalizing emails at scale, ensuring relevance for each recipient. Customer relationship management (CRM) integration is necessary to automate emails based on real-time customer data. Additionally, I test how well the platform tracks email performance, including bounce rates, conversions, and unsubscribe rates, to ensure continuous improvement.
- Lead scoring and nurturing: I want a platform that can score leads based on demographic and behavioral data. I test the accuracy of the scoring model and how easily I can adjust it. The nurturing capabilities must include automated workflows that move leads through the funnel, ensuring each prospect gets the right content at the right time. Integration with the sales team is key, so when a lead is ready for the next step, the transition is smooth. I also check if the platform provides lead activity tracking so I can monitor interactions in real-time and further tailor my outreach efforts.
- Social media management and integration: Social media is crucial, so I look for software that integrates with platforms like Facebook, LinkedIn, Twitter, and Instagram. I need to schedule posts, track engagement, and respond to messages within the platform. I also evaluate whether the tool consolidates social data into one report for tracking engagement, reach, and ROI. Social listening tools are a bonus for monitoring brand sentiment and gathering customer insights to refine our social content. Moreover, I test how well the platform can handle ad campaign management, including budget tracking and performance metrics, to ensure consistency across social media efforts.
- Artificial intelligence capabilities: I look for marketing automation software that uses machine learning and advanced algorithms to enhance marketing decisions. These technologies should improve lead scoring by predicting which leads are most likely to convert based on past interactions and customer profiles. The platform should also offer smart content recommendations to help personalize messaging at scale, as well as sentiment analysis to understand how customers feel about campaigns and content.
- Third-party integrations: CRM software integration is essential, so I test whether the software works with systems like Salesforce or HubSpot. Smooth data flow between systems ensures accurate customer records for personalized marketing. I also check for integrations with third-party tools such as eCommerce platforms, webinar software, and Google Analytics, which help centralize data and reduce manual work. Furthermore, I assess how easy it is to set up and manage these integrations, ensuring minimal friction when syncing data and automating processes.
- Analytics and reporting: I prioritize software with detailed, real-time analytics that allow me to track key metrics such as email open rates, click-through rates, and ROI. Customizable reports are important for analyzing campaign performance, and deep insights into customer behavior help refine future efforts. Predictive analytics is an added benefit for forecasting trends and optimizing campaigns. I also look for the ability to visualize data through graphs and charts, making it easier to present findings to stakeholders and guide decision-making.
- Ease of use and user interface: The platform should be intuitive, with a clean and organized interface that allows both marketers and non-technical users to navigate easily. I look for drag-and-drop functionality for building workflows, emails, and landing pages. Customization options for the interface help tailor it to my team’s needs, making the platform more efficient and less time-consuming to use. Additionally, I evaluate how customizable the dashboard is for team-specific roles and workflows, ensuring it’s set up to prioritize the most important tasks for everyone.
- Scalability and flexibility: As our business grows, I need a tool that can scale with us. The software should handle increasing leads, campaigns, and data without performance issues. It should also support complex workflows, larger audience segmentation, and multiple users across teams. Flexible pricing models ensure that the software can grow with us, avoiding the need for frequent transitions to new platforms. I also check if the platform offers advanced features for large enterprises, such as custom reporting or multi-channel campaign management, ensuring it can meet more sophisticated needs as we expand.
- Automate two or more of the following workflows: email, social media, SMS, and digital ads
- Provide advanced email marketing capabilities, including A/B testing, spam filter testing, scheduling, segmentation, and detailed performance reporting
- Act as a central marketing database for marketing information and interactions
- Allow dynamic segmentation of marketing campaign targets
- Contact targets across multiple channels after specific actions, triggers, or periods of time
- Generate forms and landing pages to collect prospect information
- Provide analytics and reports that track the entire lifecycle of a campaign, including ties to revenue and campaign return-on-investment (ROI)
- Provide personalization features to tailor marketing campaigns based on customer behavior
- Integrate with sales or marketing software such as CRM, CDP, or e-commerce platforms
- Not be categorized in the email marketing software category — products must cater to multiple channels, including email marketing
This data was pulled from G2 in 2026. Some reviews have been edited for clarity.
1. HubSpot Marketing Hub: Best marketing automation software for SEO and content optimization
I have used HubSpot Marketing Hub for over two years now. It is a premium all-in-one marketing solution that makes it incredibly easy for me to manage all of my marketing-related tasks in one place. According to G2 Data, 96% of users rated it 4 or 5 stars, 91% of users believe it is headed in the right direction, and users said they would be likely to recommend HubSpot Marketing Hub at a rate of 89%, which aligns with my experience using the platform over the past two years.
The email campaign editor is by far the most notable feature I use. The drag-and-drop editor simplifies the process of creating visually appealing emails without requiring any advanced design skills or a steep learning curve. Plus, the A/B testing functionality allows me to test different versions of my emails, ensuring I can always optimize campaigns for maximum effectiveness.
I can code a little, but creating websites? Yeah, that’s definitely not in my wheelhouse. So, I’m really impressed with the customizable landing page templates. They make it easy to create high-converting sites with minimal effort. The best part? These pages look amazing and totally do the job, with fantastic customer engagement rates to back it up.
The dashboard is also incredibly easy to understand, especially when I was new to these metrics two years ago. It helped me get up to speed quickly, providing a clear and accessible overview of my campaigns, which made tracking performance more manageable even as a beginner.

HubSpot Marketing Hub earns consistent praise for its all-in-one functionality and intuitive design. However, G2 reviewers note that pricing can feel high for smaller businesses just starting out, making it best suited for growing teams or enterprises that can fully leverage its automation, CRM, and reporting features.
Overall, HubSpot Marketing Hub stands out for its ease of use, intuitiveness, template library, and marketing dashboard. It is well-suited for content teams looking for a comprehensive marketing automation tool.

What G2 users like about HubSpot Marketing Hub:
“I love the visibility we get from HubSpot in terms of how we’re engaging different segments of our market (customers, churned customers, net new prospects, etc.). The integrations with other tools in our stack are immensely valuable. And the automations/workflows capabilities are super robust and easy to work with.”
– HubSpot Marketing Hub review, Conor B.
What I dislike about HubSpot Marketing Hub:
- HubSpot’s all-in-one setup and ease of use make marketing automation feel seamless, but some G2 reviewers mention that the pricing can be steep for smaller businesses or startups, making it better suited for larger teams.
What G2 users dislike about HubSpot Marketing Hub:
“Nothing much, it is expensive; however, we have seen value in this. There have been some small issues with email sends in the past; however, few and far between. It would also be good to have more control over contact engagement.”
– HubSpot Marketing Hub review, Jo D.
2. ActiveCampaign: Best for advanced email marketing and AI automation
ActiveCampaign is a robust AI-powered email and marketing automation tool that suggests, personalizes, and validates complex marketing campaigns. If you’re weighing what’s the best marketing automation software for startups, ActiveCampaign’s approachable learning curve, strong community, and flexible pricing make it a smart early choice that still scales. In fact, as per G2 Data, this tool is used by 92% small businesses.
From the start, I noticed how intuitive and user-friendly the interface is, which made it easy to navigate the platform and get things done efficiently. ActiveCampaign University was particularly helpful in deepening my understanding of the tool, offering a wealth of information about how to use it. The community forums were excellent resources for troubleshooting issues, providing valuable insights from other users and experts. I also really appreciated the visual automation builder, allowing me to design complex customer journeys with ease using a simple drag-and-drop interface.
One of the standout features for me was the range of tools available for email campaign creation and management. I found advanced options like A/B testing to be incredibly useful for refining my campaigns. The ability to segment email lists and send personalized automation to different groups gave me the flexibility to create more targeted content. According to G2 Data, 90% of users say ActiveCampaign meets their requirements, which reflects how well its features align with real-world marketing needs, especially for growing teams that want both flexibility and power.
Additionally, behavioral tracking provided deep insights into how my contacts interacted with my emails, website, and other touchpoints, enabling me to make data-driven decisions that improved my overall marketing efforts.

ActiveCampaign’s clean design and automation capabilities make campaign building smooth and efficient. However, G2 reviewers note that the email template library can feel limited over time, particularly for teams running frequent campaigns. For small to mid-sized businesses, though, the available templates cover most use cases effectively and help maintain consistency in design.
Still, the platform remains one of the most user-friendly and effective tools I’ve used for managing marketing campaigns. Its clean interface and strong automation features make it a reliable choice for teams that value both simplicity and performance.
What I like about ActiveCampaign:
- The intuitive, user-friendly interface made it easy for me to navigate and complete tasks efficiently.
- The visual automation builder stood out for its simplicity and flexibility. It allowed me to design complex customer journeys using a drag-and-drop interface, giving me full control over my campaigns without the need for coding.
What G2 users like about ActiveCampaign:
“What I like most is that the UI/UX is very clear and easy to use. It also has one of the best automation systems out there—I use automations a lot, and this is by far the best one I’ve worked with. I also love the CRM management: the way it filters tags and organizes everything about each contact into columns makes it very straightforward and simple to manage.”
– ActiveCampaign review, Tomás Alejandro M.
What I dislike about ActiveCampaign:
- Feedback from G2 also highlights that the email template library can feel limited over time, especially for teams running frequent campaigns. However, it is still sufficient for most SMB use cases, helping maintain a consistent design.
What G2 users dislike about ActiveCampaign:
“The contact limits can feel restrictive unless you upgrade to a more expensive plan. It would be useful to have more flexibility with the number of contacts included. Some features become costly once your list starts to grow. The pricing can rise quite quickly as you add more contacts.”
– ActiveCampaign review, James P.
3. Insider One: Best for AI-driven cross-channel customer engagement
Insider One is an AI-native omnichannel experience and customer engagement platform. As per G2 Data, 99% of users rated it 4 or 5 stars, and 96% of users said they would be likely to recommend Insider One.
One of the most powerful features is Sirius AI™, which offers AI-powered segmentation. It enables me to categorize my audience with advanced algorithms and send personalized messages at the optimal moment. This not only improves the relevance of my campaigns but also drives stronger customer engagement and conversion rates by targeting the right people at the right time.
I noted that its multi-channel marketing strategy empowers users to reach customers on their preferred platforms, whether that’s email, social media, or chat. This flexibility enables engaging users where they’re most active, making communication more relevant and impactful across different touchpoints. According to G2 Data, 95% of users say Insider meets their requirements, which reflects how effectively the platform delivers on its promise of unified, AI-driven engagement.
The smart recommender feature enhances the customer experience by delivering content that aligns with their interests. G2 reviewers mention that this ensures that users aren’t overwhelmed by irrelevant information, keeping the messaging focused and impactful, which ultimately boosts engagement.

Insider is widely appreciated for its powerful AI-driven personalization and omnichannel capabilities. G2 reviewers note that the platform’s extensive feature set can feel complex at first, especially during initial campaign setup, making it better suited for mid-size and enterprise teams with dedicated marketing operations rather than smaller teams looking for plug-and-play simplicity.
Insider One delivers a comprehensive and highly effective marketing experience. Its ability to unify data, personalize engagement, and automate complex campaigns makes it a valuable platform for businesses looking to elevate customer journeys.
What I like about Insider One:
- Insider’s multi-channel marketing strategy ensures the messages are more relevant and impactful, engaging users across email, social media, and chat.
- AI-powered segmentation is incredibly effective in targeting the right audience with personalized messages.
What G2 users like about Insider One:
“What I like best about Insider is how user-friendly and practical the platform is, while still offering strong capabilities for personalization, segmentation, automation, and omnichannel engagement. It allows teams to build customer journeys and campaigns more efficiently without making the process overly complicated. I also appreciate that Insider continues to evolve according to different industries, verticals, and customer engagement needs. The platform does not feel static; it keeps introducing new features and use cases that help brands stay relevant, improve retention, and deliver better customer experiences.”
– Insider One review, Nahvin C.
What I dislike about Insider One:
- G2 reviewers note that the wide feature set can feel complex at first, especially when building campaigns from scratch. But, they do note that Insider One’s extensive capabilities also make it one of the most versatile marketing automation platforms out there.
What G2 users dislike about Insider One:
“At the start, it took some time to prioritize the right segments and customer journeys, especially while managing multiple use cases across different client needs. That said, once we aligned with the Insider team on a few quick-win use cases, the process became much more structured, and it was easier to scale into more advanced scenarios.”
– Insider One review, Efe G.
4. Braze: Best for real-time customer messaging across multiple channels
With Braze, I could schedule alerts and mobile push notifications days or even weeks in advance. This allowed me to set up consistent communication with my audience without constant manual intervention. According to G2 Data, 93% of users believe Braze is headed in the right direction, which aligns with how innovative and forward-focused the platform feels in day-to-day use.
Braze sits among the leading marketing automation platforms for customer engagement, thanks to BrazeAI™, granular targeting, and a canvas builder that orchestrates multi-channel journeys in real time. BrazeAI™ also helped me tailor experiences, content, recommendations, and more to create unique interactions for every customer, all at scale.
The canvas builder was super intuitive and helped me design multi-channel touchpoints for users at different journey stages. G2 users state that this feature was particularly helpful in building structured, automated workflows that maintained consistency across channels while dynamically adapting to user behavior.
Using Liquid, an open-source template language developed by Shopify and written in Ruby, within Braze helped me pull user profile data into messages and customize it. This feature elevated personalization to a whole new level by dynamically inserting user-specific content into communications.

G2 reviewers also note that reporting could be more flexible, particularly when extracting specific data points or running long-term analyses due to historical data caps. For marketers focused on day-to-day performance and engagement optimization, though, Braze still provides the depth and clarity needed to track results effectively.
Overall, Braze stands out for its depth, scalability, and ability to execute complex, personalized campaigns. For marketers looking to craft data-driven customer journeys with precision, it remains one of the most capable platforms.
What I like about Braze:
- With Braze, I can schedule alerts and mobile push notifications well in advance, allowing me to set up consistent communication without manual intervention.
- The canvas builder is incredibly intuitive and helps design multi-channel touchpoints that adapt to users’ behavior.
What G2 users like about Braze:
“I love how Braze ties email, in-app messaging, and push notifications into a single platform, letting me run cross-channel campaigns for our clients efficiently. The intuitive interface makes it very easy to learn and use, and I appreciate the ability to layer different capabilities for building sophisticated, multi-step customer journeys. The customer journey mapping feature is fantastic as it shows me the whole journey clearly with segmentation and filters in one view, which helps me refine targeting and design client campaigns more deliberately.”
– Braze review, Jhoel F.
What I dislike about Braze:
- G2 reviewers highlight that reporting flexibility could be improved, as long-term trend analysis and precise data extraction require extra steps, meaning Braze is ideal for marketers focused on campaign engagement and short- to mid-term insights rather than deep, historical analytics.
What G2 users dislike about Braze:
“Some areas still need improvement. Although there are many things that make it easier, other parts remain very manual and need to be enhanced.”
– Braze review, Maicon V.
5. Klaviyo: Best for e-commerce email and SMS marketing automation
Klaviyo helps build automated customer journeys without writing a single line of code. The drag-and-drop flow builder makes it easy to visualize the entire customer journey. According to G2 Data, 96% of Klaviyo reviewers gave it 4 or 5 stars, and 91% of users are likely to recommend Klaviyo as a marketing automation platform.
From my evaluation of G2 reviews, I noted that Klaviyo works well for B2C and e-commerce brands, with its power rooted in its unified data model. Every customer click, purchase, browse, and form submission is captured into a single profile, which then fuels Klaviyo’s AI to optimize message timing, content, and segmentation. The AI-driven features, including subject line generation, send-time optimization, and predictive analytics like lifetime value (LTV) and next-order date, are frequently praised by G2 reviewers.
The segmentation engine stood out to me as a particular strength. It helps build granular audience segments based on purchase history, browsing behavior, and predictive data without needing a data team. Klaviyo’s pre-built flow templates — for abandoned cart, browse abandonment, win-back, and more — give a strong starting point to customize to match the brand’s messaging and timing.
G2 users mention that for teams already on Shopify, the native integration is particularly seamless. Revenue attribution is automatic, and product blocks can be pulled dynamically into emails without any developer involvement. Klaviyo also combines email and SMS in a single platform, which reviewers consistently praised for keeping campaigns coordinated and reducing the need for separate tools.

While Klaviyo is strong for email and SMS automation, some G2 reviewers mention that customer support can feel slow or less hands-on when resolving more complex issues. That said, teams with in-house marketing or technical expertise can still get strong value from the platform, especially once workflows, segmentation, and campaign structures are set up.
Overall, Klaviyo excels at turning customer data into personalized, automated revenu
