Best Marketing Automation Software (2026): 6 Tools Compared

The best marketing automation software for most businesses in 2026 is ActiveCampaign, which starts at $15 a month for 1,000 contacts. HubSpot Marketing Hub suits teams that want CRM and marketing in one place, while Brevo is the cheapest way to unlock unlimited workflows.

Marketing automation sends the right email or SMS when a contact takes an action. For example, a new subscriber gets a welcome series, and a lost lead gets a nudge. This guide ranks six tools on price, automation depth, ease of use and scale. All prices come from official vendor pages, checked on November 12, 2026.

Best marketing automation software: quick comparison

ActiveCampaign gives the most automation per dollar, while HubSpot gives the widest platform. The table below compares our six picks.

How we chose the best marketing automation software

We ranked each tool on public information only, using our review methodology. We did not run hands-on tests. Instead, we read pricing pages, plan limits and product documentation.

• Automation depth: workflow limits, branching and cross-channel steps.
• Price: starting price and how fast it climbs with contacts.
• Free plan: whether you can start at $0.
• Ease of use: how much setup a small team needs.
• Scale: what the top tiers add for larger teams.

Each pick then received an editorial rating from 0 to 10. Automation depth and price carry the most weight, because those two factors decide value. We also noted where a vendor page hides prices or shows promotional rates, since that makes budgeting harder. Where we could not confirm a figure on the official page, we point you to current pricing instead of guessing. That way, every number in this guide traces back to a public vendor source.

What is the best marketing automation software in 2026?

The best marketing automation software depends on your sales model and list size. Here are our six picks, with prices as of November 2026.

ActiveCampaign: best marketing automation software overall

ActiveCampaign offers deep automation at a small-business price. Its plans start at $15 a month for Starter, $49 for Plus, $79 for Pro and $145 for Enterprise, all at 1,000 contacts.¹ Starter allows up to 5 actions per automation and email only. Plus and higher plans unlock unlimited actions and cross-channel automation.

There is no free plan. Instead, ActiveCampaign invites you to:

Try it free for 14 days.

So you can build a real welcome series before you pay. Read our full ActiveCampaign review for more detail.

Rating: 8.7/10. ActiveCampaign balances power and price well. However, Starter's five-action cap means most teams need Plus.

HubSpot Marketing Hub: best marketing automation software for CRM-led teams

HubSpot Marketing Hub is the most complete platform on this list. Its free tools cover up to 2 users with 2,000 email sends a month and 1 automated email action.² HubSpot's pricing page sums up the free tier simply:

Free for up to 2 users. No credit card required.

The jump to paid automation is steep, though. Professional starts at $800 a month with 3 seats, 2,000 marketing contacts and up to 300 workflows. It also carries a one-time $3,000 onboarding fee. Enterprise starts at $3,600 a month with 10,000 contacts, 1,000 workflows and a $7,000 onboarding fee.

Rating: 8.4/10. HubSpot wins on breadth and its built-in CRM. Still, its Professional price puts it out of reach for many small teams.

Brevo: best budget marketing automation

Brevo prices by email volume rather than contacts. According to Brevo's pricing file, Starter costs $9 a month on monthly billing for 5,000 emails.³ Standard costs $18 a month and is the first plan that lists unlimited multi-step workflows. Brevo describes that feature this way:

Create an unlimited number of automated, multi-step workflows to engage users at key moments along their journey.

The free plan allows up to 300 emails a day. As a result, Brevo suits teams with big lists but modest sending.

Rating: 8.2/10. Brevo is the value pick. On the other hand, its automation builder is simpler than ActiveCampaign's.

Klaviyo: best marketing automation for ecommerce

Klaviyo focuses on online stores and their customer data. Its free plan covers up to 250 active profiles and 500 emails a month.⁴ Paid plans start at $20 a month for Email and $25 a month for Email and SMS, both at 500 profiles. In addition, campaigns and flows run on every plan.

Klaviyo reported more than 205,000 customers as of June 30, 2026, in its Q2 2026 results.⁵ See our Klaviyo review for store-specific features.

Klaviyo also ran a limited-time offer that made the first month of its Marketing plan $1 in November 2026. So check the current terms before you sign up.

Rating: 8.0/10. Klaviyo leads for ecommerce. However, B2B teams will find its focus too narrow.

Mailchimp: best for simple newsletters with light automation

Mailchimp is the easiest starting point for small lists. Its free plan covers 250 contacts and up to 500 sends a month, but it has no automation flows.⁶ Paid plans start at $13 a month for Essentials, $20 for Standard and $350 for Premium. Mailchimp labels these as prices for the first 12 months, so expect a change at renewal.

Essentials allows up to 4 flow steps, while Standard allows up to 200 flows. Our Mailchimp review covers the full feature set.

Rating: 7.6/10. Mailchimp is simple and familiar. Still, serious automation starts only on Standard.

Adobe Marketo Engage: best enterprise marketing automation

Marketo Engage targets enterprise B2B marketing teams. For enterprise marketing automation, Adobe offers four packages, Growth, Select, Prime and Ultimate, and does not publish prices. Its pricing page simply invites you to:

Get customized pricing for Marketo Engage.

Rating: 7.5/10 for small teams. Marketo is powerful, but it needs a dedicated admin and a large budget. Compare it in our HubSpot vs Marketo guide.

Best marketing automation software by team size

Team size changes which tool gives the best value. Here is how our picks map to common team shapes, based on plan limits as of November 2026.

Solo founders and teams of one or two

Start free or near free. HubSpot's free tools and Klaviyo's free plan both cover the first few hundred contacts. If you need multi-step workflows, Brevo Standard at $18 a month is the cheapest step up. So for a founder, the best marketing automation software is often the one that costs nothing until revenue arrives.

Small marketing teams of three to ten

ActiveCampaign Plus fits this size best. It unlocks unlimited automation actions and cross-channel steps for $49 a month at 1,000 contacts. In addition, it leaves budget for content and ads, which matter more at this stage than extra features.

Larger teams with sales and marketing alignment

HubSpot Marketing Hub Professional or Enterprise makes sense here. Professional includes 3 core seats and up to 300 workflows, while Enterprise includes 5 seats and up to 1,000 workflows. Large B2B teams with a dedicated admin may also look at Marketo Engage.

Overall, the best marketing automation software for small business is not always the one with the most features. It is the one your team will actually use every week.

Which automation features matter most?

Unlimited workflow steps and clear pricing matter most. The matrix below compares four popular picks, based on vendor pages as of November 2026.

So the right choice depends on your channels. For instance, an online store will value Klaviyo's email and SMS plan for marketing automation for ecommerce, while a B2B team will value ActiveCampaign's cross-channel automation on Plus.

What does marketing automation pricing look like?

Most small teams pay $15 to $50 a month for real automation at 1,000 contacts. Marketing automation pricing then rises with your list size and the number of channels.

Watch three hidden costs. First, HubSpot charges onboarding fees of $3,000 on Professional and $7,000 on Enterprise. Second, Mailchimp's listed prices apply to the first 12 months only. Third, SMS often bills as credits on top of the plan price.

ActiveCampaign vs HubSpot: which suits a small team?

ActiveCampaign suits most small teams better on price, while HubSpot suits teams that want one CRM for everything. The gap in cost is large.

ActiveCampaign Plus costs $49 a month at 1,000 contacts and unlocks unlimited automation actions. HubSpot Professional, by contrast, starts at $800 a month and adds a $3,000 onboarding fee. So a small team would pay $588 in year one on ActiveCampaign Plus. The same team would pay $12,600 on HubSpot Professional, onboarding included.

On the other hand, HubSpot bundles a full CRM, landing pages and reporting in one place. That saves time if sales and marketing share data every day. Also, HubSpot's free tools let a founder start at $0 and upgrade later.

In short, pick ActiveCampaign if automation is the main job. Pick HubSpot if you want one system for the whole customer journey and have the budget. Teams that need SaaS marketing automation, such as trial nurture flows, can build them in either tool.

Brevo vs Mailchimp: which is better for budget automation?

Brevo is better for budget automation, because it unlocks unlimited workflows for less. Brevo Standard costs $18 a month on monthly billing and lists unlimited multi-step workflows. Mailchimp Standard costs $20 a month and allows up to 200 flows.

Brevo also prices by email volume, not contacts. As a result, a team with a large list but few sends pays less. Mailchimp, however, prices by contacts and labels its prices as first-year rates. So check the renewal price before you commit.

Still, Mailchimp's interface feels simpler for a first newsletter. Teams that only need a welcome email and a monthly update may prefer it.

Is there free marketing automation software?

Yes, but free plans limit automation heavily. HubSpot, Brevo, Klaviyo and Mailchimp all offer a free tier as of November 2026.

• HubSpot: free for up to 2 users, with 1 automated email action and 2,000 sends a month.
• Klaviyo: free for 250 active profiles and 500 emails a month, with flows included.
• Brevo: free for up to 300 emails a day.
• Mailchimp: free for 250 contacts and 500 sends a month, but with no automation flows.

So Klaviyo's free plan offers the most automation at $0. Free marketing automation software works for testing. However, most growing teams outgrow it within a few months.

Which automations should you build first?

Start with the automations that earn or save the most per contact. These five cover most small businesses.

• Welcome series: three to five emails that introduce your brand after signup.
• Lead nurture: a sequence that moves a trial user or lead toward a sale.
• Abandoned cart or form: a reminder when someone stops before buying or booking.
• Win-back: a message to contacts who have not opened or bought in months.
• Internal alerts: a note to sales when a lead hits a score or visits a pricing page.

Build one at a time, then measure it for two weeks. After that, adjust the timing and copy before you add the next flow. This steady approach beats launching ten flows that nobody maintains.

How long does marketing automation take to set up?

A small team can launch its first workflow in a day and a full setup in a few weeks. The main time cost lies in content, not software.

For example, a welcome series needs three to five well-written emails. Lead scoring needs agreement between sales and marketing on what a good lead looks like. Meanwhile, HubSpot's paid onboarding on Professional and Enterprise adds a guided setup, which helps larger teams.

So plan your content first. Then the tool setup goes quickly on any of our picks. Also, set aside an hour each month to review open rates, clicks and unsubscribes for every live flow. Small changes, such as a better subject line or a shorter delay, often lift results more than a new tool would. In addition, retire flows that no longer match your offer, because stale messages hurt trust. Over a year, this simple routine keeps your automation fresh and your list healthy.

Why compliance matters in marketing automation

Automation sends email at scale, so a single mistake repeats across thousands of contacts. According to the FTC's CAN-SPAM compliance guide, each separate email in violation can draw penalties of up to $53,088, as listed on the page in November 2026.⁷

So check that every tool you consider handles unsubscribes, sender details and consent records. Still, the setup of your forms and lists remains your job. For example, import only contacts who agreed to hear from you. Also, add your physical postal address to every footer, since CAN-SPAM requires it. Finally, honor opt-out requests promptly and keep a record of consent for each contact. These habits protect your sender reputation as well as your legal standing, which keeps more of your emails in the inbox.

How to choose the best marketing automation software for small business

Start with your sales model, then match the tool to it. This one step removes most of the options.

• B2B with a sales team: ActiveCampaign or HubSpot.
• Online store: Klaviyo.
• Large list, small budget: Brevo.
• Simple newsletter with a few flows: Mailchimp.
• Enterprise lead management: Marketo Engage.

Next, map your first three automations on paper, such as welcome, lead nurture and win-back. Then build them during a free trial or free plan. Also, export a sample report to check that the analytics answer your real questions.
