15 Best Marketing Automation Platforms Compared (2026)

“Marketing automation platform” covers a wider range than most best-of lists admit — a $9-a-month Brevo plan and a six-figure Marketo enterprise contract both fall under the same category label. Most ranking pages stay at one end of that range or blur automation platforms together with plain CRM or SMS tools. This page compares 15 platforms across the full range, then goes deep on the decisions people actually get stuck on: HubSpot vs. Marketo, ActiveCampaign vs. Mailchimp, what “enterprise” pricing really costs once the extras are added, the genuinely cheapest options, and the strongest fit for ecommerce.

For the larger case for automating your marketing in general, look at fundamentals of marketing automation.

Marketing automation platform: a software that activate automated, targeted marketing actions ( e-mails, SMS, added to ad audience) depending on a contact‘s activity, lifecycle phase or properties

HubSpot vs Marketo comparison

Choose HubSpot if you have less than approximately 500 staff and want a unified solution of marketing, CRM and sales in one predictable package. Choose Marketo if you are a large B2B enterprise already invested in either Salesforce or Adobe Experience Cloud with a dedicated marketing operations team to operate it.

The cost gap is bigger than either vendor’s list price suggests. HubSpot Marketing Hub Enterprise is about $38K–$48K per year and includes the CRM, reporting and CMS tools, all natively, at no additional platform fee. Marketo Engage is typically $36K–$120K+ per year pre-implementation ( an additional $15K–$40K for services, then a certified admin, who costs $85–$120K annually, for a dedicated hire). Additionally, HubSpot is the faster one to get live most teams are able to run campaigns within days, whereas Marketo can require weeks of implementation with a certified consultant before the first campaign will be sent.

The one area where Marketo still wins hands down is extreme-scale segmentation: its Smart List engine manages extremely large databases something in the range of 500,000 to 2 million+ contacts with deep, nested filter logic without the slowdown that can occur for some HubSpot customers at a size of about 500,000 contacts. If your database and filtering needs are genuinely at that scale, Marketo’s cost premium buys something HubSpot doesn’t yet match. For most companies below that scale, the cost difference is hard to justify against what HubSpot now delivers.

ActiveCampaign vs Mailchimp

Pick ActiveCampaign if the level of automation really does influence the way you do marketing. Pick Mailchimp if the shortest route to sending a newsletter (preferably for free) is what you really need.

The gap isn‘t close on automation today: ActiveCampaign‘s automation builder, for instance, has well over 100 different trigger types and hundreds of ‘recipes’ built-in, and by independent testing migration data consistently runs from Mailchimp back toward Active Campaign rather than forward. Mailchimp‘s automations, on the other hand, max out at basic if/else logic with no multi-channel flows. Active Campaign also includes a basic CRM with deal pipelines and lead scoring, which Mailchimp doesn’t offer at all — sales teams working the same contact list as marketing would need a separate tool alongside Mailchimp.

Mailchimp’s advantage is speed and price at the entry level: a free plan (now capped at 250 contacts with automation stripped out) and paid plans starting around $13/month with genuinely fast setup. ActiveCampaign has no free plan, starts around $15/month, and comes with a real learning curve — worth it if you’ll use the automation depth, overkill if you’re sending occasional newsletters. For a sense of what that automation depth actually looks like in practice, see documented workflow examples across lead nurturing, onboarding, and retention.

Enterprise marketing automation software

“Enterprise” pricing is rarely the number on the pricing page — implementation, admin headcount, and add-on modules typically double or triple a platform’s list price by the time it’s actually running.

Pedowitz Group’s cost breakdown shows the pattern clearly for Marketo: a base Marketo Engage license around $36,000–$72,000/year, plus a separate Marketo Measure attribution add-on at $12,000–$36,000/year, plus $15,000–$40,000 in implementation services, plus $85,000–$120,000/year for a dedicated certified admin. The same math applies across the enterprise tier generally — Braze (generating $593M ARR from 2,300+ customers) and Salesforce Marketing Cloud both carry custom enterprise pricing where the quoted number is a starting point, not the full cost.

Which of the three fits depends on existing infrastructure more than feature comparison. Braze: optimal for teams requiring AI-powered omnichannel personalization at the largest scale where there is weak CRM reliance. Salesforce Marketing Cloud: optimal if you are already heavily invested in the Salesforce ecosystem wanting a unified CDP across CRM, digital and offline channels. Marketo: optimal for Adobe- or Salesforce-adjacent companies needing multi-touch attribution in long B2B sales funnels.

Cheapest marketing automation tool

Brevo posts the lowest genuine entry price among platforms with real automation, not just email sending, at roughly $9/month. GetResponse follows close behind at about $13.30/month for its base plan — but that number is misleading on its own.

The trap with “cheapest” claims in this category: the lowest advertised price often doesn’t include automation at all. GetResponse’s automation features specifically require its separate Marketing Automation plan, starting around $40/month, not the $13.30 base tier. Mailchimp’s free plan dropped automation entirely as of early 2026, leaving it as email-only until you upgrade. ActiveCampaign, at roughly $15/month for its Starter tier, includes automation from the entry price with no separate paid gate — worth weighing against Brevo’s lower sticker price if automation is the actual reason you’re buying the software. Before comparing entry prices of any of these, check specifically if automation is included or sold separately.

Marketing automation for ecommerce

Klaviyo is still the default for Shopify-first DTC brands, Omnisend offers the better value if you‘d like SMS and web push included from the start, and Drip is at least worth a glance if you care about attribution and segmentation complexity over saving a few bucks.

Klaviyo begins at 45/month for email only or 60/month for email plus sms (15k email sends, 1250 SMS credits included) compared to a free tier limited to 250 profiles. It’s the most advanced ecommerce attribution and behavioral segmentation in this list, integrating live with Shopify, WooCommerce, Magento for live order and customer data. Omnisend starts 11.20/month at 500 contacts and makes SMS and web push equal citizens to email (rather than add ons), a better starting point if multichannel messaging is more relevant than depth of segmentation. Drip, at roughly $39/month, is priced above both but built specifically around store data rather than as a generic email tool with an ecommerce plugin added on, which shows in its revenue attribution and pre-built cart, browse-abandonment, and win-back workflows.

Q&A Access Is More Convenient

What’s the difference between marketing automation and email marketing software?

Email marketing software focuses on sending and automating email specifically. A marketing automation platform coordinates triggers and actions across multiple channels — email, SMS, push, ads, and CRM records — from the same underlying behavioral data. If email is genuinely your only channel, a dedicated comparison of email marketing platforms covers that narrower category directly.

Is HubSpot or Marketo better for enterprise?

HubSpot for most companies under roughly 500 employees, once real total cost of ownership is factored in rather than list price alone. Market when your contact database is large enough and complicated (say 500,000+ contacts and lots of segmentation) to make it worth the extra up front and admin costs, and especially if you‘re already on Adobe or Salesforce architecture.

How much does marketing automation software cost?

On the low end, approximately $9–$15 per month at entry for a system like Brevo or ActiveCampaign. On the high end, $36,000–$120,000+ per year at the enterprise level once implementation and a dedicated admin are in included. The gap between list price and real cost is largest at the enterprise end.

What’s the best marketing automation platform for small business?

ActiveCampaign is the most consistently recommended pick across independent comparisons for small businesses that want real automation depth without enterprise pricing. Mailchimp works if the actual need is closer to email marketing than full automation.

Do I need a CRM built in, or a separate one?

If sales and marketing are working on the same contacts, one platform (HubSpot, ActiveCampaign) avoids duplicating contacts and syncing between the two systems. If an advanced CRM is already in place (Salesforce), a marketing automation platform, that do not compete with CRM (Marketo, Braze, Customer.io), get on more easily.

Where to start

Match your pick to what your team can actually run, not the platform with the longest feature list — a $15-a-month ActiveCampaign plan someone actually uses beats an underused enterprise contract every time. Once you’ve picked a platform, a phased rollout roadmap covers how to sequence the first 90 days.
