What AI said about marketing automation software in September 2026

Below is a practical shortlist of marketing automation software people actually use—not obscure tools that only appear in affiliate listicles. I’d pick based on company type, CRM, and channel mix.

G2’s 2026 marketing automation picks include HubSpot, ActiveCampaign, Braze, Klaviyo, Omnisend, Customer.io, Mailchimp, and others, while Enlyft’s install-base data shows broad real-world usage led by HubSpot and ActiveCampaign. In B2B specifically, Sagefrog’s 2026 B2B Marketing Mix Report lists Zoho, Salesforce Marketing Cloud, Pardot/Account Engagement, Mailchimp, Marketo, HubSpot, and Constant Contact among widely used platforms.

My quick recommendations

• Best overall: HubSpot Marketing Hub

• Best if you live in Salesforce: Salesforce Marketing Cloud Account Engagement

If you want the lowest-risk shortlist to demo, I’d start with HubSpot, ActiveCampaign, Klaviyo, Marketo, and Salesforce Account Engagement—then add Braze or Customer.io if your business is more product/app/lifecycle-driven than traditional lead-gen-driven.

Best Marketing Automation Software

Based on current reviews and widespread usage, here are the top platforms — organized by who they're best for:

Enterprise / Large Teams

• Adobe Marketo Engage — A leading AI-powered platform that automates and scales marketing to drive engagement, efficiency, and revenue. Popular with large B2B organizations needing deep customization.
• Salesforce Marketing Cloud — Strong for enterprises already in the Salesforce ecosystem; helps generate high-quality leads, increase lead and account conversion, and drive efficient growth with marketing automation.

All-in-One / B2B Favorite

• HubSpot Marketing Hub — If your world is B2B, long sales cycles, and tight sales-marketing handoff, HubSpot and ActiveCampaign are built for that. It's widely regarded as works well for inbound-focused B2B teams that want an all-in-one CRM.

Best for Small Businesses

• ActiveCampaign — Frequently cited as the top pick for smaller teams: for most small businesses, ActiveCampaign is the best marketing automation platform. It's also praised because ActiveCampaign offers sophisticated automation at small business prices.

Best for Ecommerce

• Klaviyo — Klaviyo is popular with growing ecommerce brands for its prebuilt flows and predictive analytics.
• Drip — For ecommerce and DTC brands, Drip is a strong fit, purpose-built for online stores, with real-time Shopify and WooCommerce sync, revenue attribution, and pre-built workflows for carts, browse abandonment, and win-backs.
• Omnisend — another ecommerce-focused contender frequently listed alongside Klaviyo.

AI-Powered Personalization (Omnichannel)

• Bloomreach — For brands that need AI-powered personalization across email, SMS, web, mobile, ads, and search, Bloomreach is a strong choice across industries, including retail, financial services, and travel and hospitality.
• Braze and Insider — also frequently mentioned for advanced, behavior-driven omnichannel journeys.

Other Widely-Used Names

Other tools that consistently show up in "most used" lists include HighLevel, Attentive, Customer.io, and Intuit Mailchimp All-in-One Marketing Platform, plus Brevo (formerly Sendinblue), which is popular for its combination of affordability and CRM features.

How to Choose

There's no single "best" — it depends on your business:

• There's only the best one for the business you're actually running.
• If you're ecommerce, prioritize Klaviyo or Drip for their native store integrations and revenue attribution.
• If you're B2B with a sales team, HubSpot or ActiveCampaign offer the tightest CRM-marketing alignment.
• If you're enterprise-scale, Marketo or Salesforce Marketing Cloud offer the depth and integrations larger orgs need.
• If AI-driven omnichannel personalization (SMS, push, ads, web) is the priority, Bloomreach or Braze lead the pack.

A general rule from reviewers: Some platforms focus on email alone, not all platforms integrate AI with the same depth, and many were built for B2B workflows that don't translate to the speed and scale of modern consumers — so match the tool to your actual channel mix and sales cycle rather than picking by brand recognition alone.

The most widely recommended marketing automation platforms are HubSpot Marketing Hub, ActiveCampaign, Brevo, Klaviyo, Omnisend, and Mailchimp. Across the sources you provided, HubSpot is the most common “best overall” pick, while ActiveCampaign is repeatedly favored for strong automation at a lower price point.

If you want the top brands people actually use, the most practical shortlist is:

• HubSpot — best overall / all-in-one CRM + marketing automation, especially for B2B and growing teams.
• ActiveCampaign — best for deep automation and lead nurturing without the cost of enterprise tools.
• Brevo — strong budget-friendly option for email, SMS, and multi-channel automation.
• Klaviyo — especially strong for e-commerce and user-friendly automation.
• Omnisend — one of the most common e-commerce choices, especially for Shopify-style stores.
• Mailchimp — still widely used for simpler email marketing and basic automation.

A more specific recommendation by use case:

• Best overall: HubSpot. Multiple sources rank it as the top all-in-one platform, especially when you want CRM, forms, workflows, and marketing automation in one system.
• Best for small and growing businesses: ActiveCampaign. It is repeatedly described as the best value for serious automation depth at a manageable price.
• Best for e-commerce: Klaviyo or Omnisend. Both are consistently called out as strong e-commerce-first platforms.
• Best budget option: Brevo. It appears in several roundups as the affordable all-in-one choice.
• Best for enterprise / advanced B2B: Adobe Marketo Engage or Salesforce Marketing Cloud Account Engagement (Pardot). These show up in the enterprise/B2B-focused lists.

If you want the safest “people actually use it” pick:

• Choose HubSpot if you want the most established all-in-one platform.
• Choose ActiveCampaign if you want strong automation with better pricing.
• Choose Klaviyo if you run an online store.

If you want, I can also give you a top 5 ranked list by business type: small business, B2B SaaS, e-commerce, agencies, or enterprise.

There’s no single “best” marketing automation platform—it depends on your business type (B2B vs. B2C), budget, team size, and channels. But these are the most widely used and highly regarded tools:

If you tell me your business size, budget, and channels you want to automate (email, SMS, social, ads), I can recommend the best fit for your exact situation.

The right marketing automation software depends heavily on your business model, budget, and company size. The market is divided into clear categories based on what teams actually use day-to-day.

To help you find the best fit, the top-rated platforms are organized below by their specific strengths.

Best All-in-One & B2B Platforms

These tools connect your marketing efforts directly to a Customer Relationship Management (CRM) system, making them ideal for lead generation and aligning marketing with sales teams.

HubSpot Marketing Hub: The undisputed market leader for mid-market to enterprise inbound marketing. It features a highly intuitive visual workflow builder, built-in forms, and deep CRM integration. While it offers a fantastic user experience, pricing scales up steeply as you add contacts. ActiveCampaign: Widely regarded as having the most powerful and flexible automation logic for small-to-medium businesses (SMBs). It allows you to build highly complex, behavior-driven user journeys without requiring an enterprise budget.

Best for E-Commerce & Retail

If you run an online storefront, you need event-driven data platforms that trigger messages based on cart abandonment, purchase history, and product browsing.

Klaviyo: The reigning favorite for Shopify and e-commerce brands. It pulls real-time data directly from your store to build precise SMS and email segmentations. It excels at multi-channel revenue attribution so you can see exactly how much money your flows generate. Drip: A strong, slightly more budget-friendly alternative to Klaviyo that focuses purely on DTC (direct-to-consumer) lifecycle flows like win-back campaigns and post-purchase follow-ups.

Best for Startups & Simple Email Campaigns

For smaller teams or businesses just starting with automation, these platforms minimize technical friction.

Intuit Mailchimp: The most universally used entry-level platform. It is excellent for straightforward newsletters, simple pre-built welcome journeys, and basic landing pages. Brevo: An incredibly cost-effective multi-channel option. Unlike most platforms, Brevo charges based on email volume rather than the size of your contact list, making it ideal for budget-conscious companies with large databases.

Best for Large Enterprises

These massive platforms are built for global organizations handling highly complex data structures and strict regional compliance rules.

Adobe Marketo Engage: The corporate heavyweight for B2B demand generation and account-based marketing (ABM) at massive scale. It requires a dedicated administrator to run but offers unmatched multi-touch campaign analytics. Salesforce Marketing Cloud: The go-to solution for companies already deeply embedded in the Salesforce ecosystem. It leverages advanced unified data clouds and AI agents to coordinate massive omnichannel footprints across email, text, ads, and mobile apps.
