12 Best AI-Powered Marketing Automation Platforms in 2026, Compared

HubSpot Marketing Hub is the default pick when you want marketing automation sitting on top of a real CRM rather than bolted onto an email tool. The Starter plan covers email campaigns, forms, landing pages, live chat and automation for $20 per seat a month, with 1,000 marketing contacts included, and the free tier handles 2,000 sends a month for teams that are just starting.

The catch is the cliff between Starter and Professional: $890 a month billed monthly, $800 annually, plus a $3,000 onboarding fee, and marketing contacts are sold in blocks on top. New customers may see a lower first-year promo price on the pricing page, but budget on the $20 list price. Buy HubSpot when your sales team already lives in its CRM; otherwise the cheaper tools below do the same email jobs for less.

ActiveCampaign is the automation-first pick in this list: the visual builder supports branching, goals and multi-trigger journeys from the $19-a-month Starter plan, and its Active Intelligence features — an AI campaign builder, suggested segments and an automation builder — are included rather than sold as an add-on. A built-in CRM with deal pipelines and lead scoring means sales follow-up lives in the same account.

Starter is deliberately limited: five actions per automation, so a serious onboarding sequence needs Plus at $49 a month. There is no free plan, only a 14-day trial, and because pricing is contact-based, a list that grows from 1,000 to 5,000 contacts pushes Starter from $19 to $79 a month. For a small business that wants real automation depth at a small-business price, it is the strongest value here.

Mailchimp is still the easiest way into email marketing: the Essentials plan costs $13 a month for 500 contacts, the builder is the most beginner-friendly here, and the Shopify and WooCommerce integrations make purchase-triggered emails nearly automatic. Standard at $20 a month is where it becomes a real automation tool, with multi-step customer journeys, predictive segmentation and send-time optimization.

Watch the billing rules. Mailchimp counts unsubscribed contacts toward your tier, so a neglected list costs money, and the free plan shrank in early 2026 to 250 contacts and 500 sends a month. The AI layer, Intuit Assist, is still in beta and limited to Standard and Premium in four countries. Pick Mailchimp for simplicity and ecommerce; pick ActiveCampaign when journeys get complex.

Brevo is the cheapest way into paid marketing automation: Starter costs $9 a month for 5,000 emails, the free plan sends 300 emails a day with up to 100,000 contacts stored, and email, SMS, WhatsApp and a CRM all live in one account. Because Brevo charges by send volume rather than contacts, a big list that emails rarely costs far less here than on contact-priced rivals.

The $9 headline needs reading carefully. Starter keeps Brevo branding on your emails unless you add the $9-a-month removal add-on, full multi-step automation starts on Standard at $18 a month, and the $9 tier only stores 500 contacts. Even so, for a small business sending a weekly newsletter plus a welcome sequence, Brevo is hard to beat on price.

Klaviyo is the ecommerce specialist: its flows for abandoned carts, browse abandonment and post-purchase follow-up are ready-made for Shopify and WooCommerce, and predictive analytics for churn risk, next order date and lifetime value come with the paid plans. The AI flow builder turns a plain-language description into a complete multi-channel flow, and the free plan covers 250 active profiles.

Billing follows active profiles, not sends, so every profile you could email costs money whether you mail them or not — list hygiene is a budget decision here. The Email plan starts at $20 a month for 251 to 500 profiles and climbs with the list ($150 at 10,000), with SMS billed separately. If you sell online, Klaviyo usually pays for itself; if you do not, the cheaper generalists fit better.

Keap is the all-in-one for service businesses: CRM, sales pipeline, appointment booking, quotes, invoices and payments sit next to email and SMS automation, and its template library carries two decades of small-business campaigns. The AI Content Assistant and AI Automation Assistant can build a campaign from a template in minutes, and every account includes a dedicated Customer Success Manager.

The price is the honest problem. Keap simplified to a single plan at $249 a month billed annually ($299 monthly) for 1,500 contacts and 2 users, and a required implementation package starts at $500 on top. Older Lite, Pro and Max prices still circulate on comparison sites, but they are outdated. Choose Keap when you want the whole business in one system; choose ActiveCampaign when you only need the marketing.

Customer.io is built for teams whose messages start with what users do inside the product: signups, trial activity, feature usage and billing events trigger email, push, in-app, SMS and WhatsApp from one visual workflow builder. Essentials costs $100 a month billed monthly for 5,000 profiles and a million emails, with unlimited seats and an AI Agent included.

There is no free plan, only a 14-day trial, and early-stage companies that raised under $10 million can apply for 12 months free through the Startup Program. The step to Premium is steep at $1,000 a month billed annually. For a SaaS team sending lifecycle email from product data, Customer.io is the most direct tool here; for a simple newsletter list, it is overkill.

Salesforce Marketing Cloud is the enterprise end of this list: Journey Builder runs email, SMS, push and WhatsApp from one customer profile, Agentforce builds campaigns and Einstein picks send times, and everything sits natively on the Salesforce platform with Data 360, so there is no CRM sync to maintain. The published entry is Starter at $25 per user a month, with a free trial.

Read that entry price carefully. Starter is a light CRM bundle; the marketing automation most buyers want starts at Growth, $1,500 a month per org billed annually, and Advanced is $3,250. Implementation commonly takes three to six months, and the add-ons — Personalization from $8,000 a month, Marketing Intelligence from $10,000 — are enterprise budgets. Buy it when Salesforce is already your system of record; otherwise it is far more platform than a small team needs.

Marketo Engage is the B2B workhorse: engagement programs, lead scoring and grading, and revenue-cycle modelling are built for sales cycles that run months, not days, and Target Account Management supports real account-based marketing. Its Smart Campaigns trigger on nearly any behavior or data change, and the Salesforce and Microsoft Dynamics integrations are the deepest in this list.

Adobe publishes no pricing at all — Growth, Select, Prime and the highest package are all custom annual quotes driven mainly by database size — and there is no free plan or trial, only demos. Reviewers also rate the interface the most dated here and the learning curve the steepest. Choose Marketo when B2B lead management is the job; for simpler campaigns, HubSpot or ActiveCampaign cost less and move faster.

Braze is the category leader for consumer brands with serious mobile apps: one customer profile, fed by real-time event streaming, drives push, in-app messages, SMS, email and web messages from a single Canvas journey, with Liquid templating for personalization and BrazeAI suggesting segments and content. It holds a 4.5 out of 5 G2 rating from 1,985 reviews, the strongest enterprise score here.

There is no public price and no free tier — only a free trial and a sales conversation, with contracts priced on monthly active users and message credits and entry deals typically running into five figures a year. Salesforce agreed to acquire Braze for $5.66 billion in October 2026, with the deal expected to close in early 2027. Choose Braze when mobile engagement is the business; smaller teams should start with Klaviyo or Customer.io.

Iterable is the cross-channel lifecycle platform for teams that outgrow email-first tools: Workflow Studio runs email, push, SMS and in-app journeys from one canvas, and catalog-driven personalization pulls product or content data into every message. It scales from growth-stage to enterprise without a rebuild, and its data integrations keep segments synced with the warehouse or CDP.

The buying process is fully sales-led — no published pricing, no free trial, no self-serve checkout — and contracts are annual, with third-party deal data putting most in five figures a year and up. Reporting is also the weak spot reviewers mention most: it covers campaign basics but not the deeper analysis, so mature teams pair it with a BI tool. Shortlist Iterable when cross-channel orchestration justifies an enterprise contract.

MoEngage competes head-on with Braze and Iterable for the consumer-brand lifecycle budget, leading with Sherpa AI: churn prediction, best channel and best send time, and journey-path optimization run inside Flows, which orchestrate push, in-app, email, SMS, WhatsApp and web from one builder. It counts 1,350-plus customers and is strongest with consumer apps, retail, food delivery and fintech brands.

Pricing is quote-only on monthly tracked users, with Growth and Enterprise plans carrying a one-year minimum and no published dollar figure; Cards, Personalize and connected channels such as WhatsApp are add-ons on both tiers. Reviewers like the segmentation and the no-code builder but flag slow dashboards on large datasets. Choose MoEngage when you want Braze-style AI journeys at a lower entry point and can buy through sales.
