1. HubSpot Marketing Hub
HubSpot lets you run email, forms, landing pages, ads, and a CRM from one login. The free CRM is genuinely usable. Marketing Hub Starter costs about $15 per seat per month on annual billing, or $20 month to month, and includes 1,000 marketing contacts and simple automation.
The problem is the next step. Professional starts at $890 per month with three seats and 2,000 contacts, plus a one-time $3,000 onboarding fee. Full workflows, A/B testing, and custom reports sit on this plan. A team that outgrows Starter can see its bill jump more than 40 times.
HubSpot is worth it when sales and marketing share the same contact records. For email automation alone, cheaper tools work fine.
2. ActiveCampaign
ActiveCampaign has one of the most flexible automation builders at its price. Workflows can branch based on tags, email clicks, site visits, and form answers.
Prices at 1,000 contacts, billed annually:
- Starter: $15/month
- Plus: $49/month
- Pro: $79/month
- Enterprise: $145/month
Look closely at Starter. Each automation is capped at five actions, so most buyers who pick ActiveCampaign for automation end up on Plus or higher. Accounts opened since November 2025 also count every contact toward the limit, including unsubscribed ones. There is no free plan, only a 14-day trial.
3. Brevo
Brevo, formerly Sendinblue, charges mainly by emails sent rather than contacts stored. For a business with a big list that emails a few times a month, this can be the cheapest setup here.
The free plan sends up to 300 emails a day. Starter begins at $9 a month, but it keeps Brevo branding unless you pay for an add-on. For real automation work, look at Standard. It starts at $18 a month and adds A/B testing and full automation without the logo. The next plan, Professional, jumps to $499 a month.
Brevo also includes SMS, WhatsApp, and a basic CRM. Lower plans now have contact caps, so check yours first.
4. Klaviyo
Klaviyo is built for ecommerce. It pulls order history, browsing activity, and product data from stores like Shopify, then uses that data to trigger flows such as abandoned cart and post-purchase emails. Predictive analytics and AI-generated segments are included on paid plans.
The free plan covers 250 active profiles and 500 emails a month. The email plan starts at $20 a month, and email + SMS starts at $35 a month.
One billing detail matters. Klaviyo charges by active profiles, meaning anyone you can contact counts, even if you did not email them that month. Suppress unengaged profiles every few months.
5. Mailchimp
Mailchimp is still the tool most beginners know. The editor is easy, and it has many templates and integrations.
Its free plan keeps shrinking. It now covers 250 contacts and 500 emails a month, with no multi-step automation. Essentials starts at $13 a month. For branching customer journeys, you need Standard, which starts at $20 a month for 500 contacts and runs about $100 a month at 5,000 contacts.
Mailchimp counts unsubscribed contacts toward your plan, too. Archive them regularly.
6. Zoho Marketing Automation
Zoho Marketing Automation makes the most sense for businesses already using Zoho CRM. Leads, scores, and campaign activity sync between the two without a third-party connector.
It covers journey building, lead scoring, segmentation, SMS, web forms, and landing pages. Paid plans start under $20 a month for small lists, and a free trial is available. Outside the Zoho ecosystem, ActiveCampaign or Brevo is usually the better pick.
7. MailerLite
MailerLite is a clean, simple tool for creators and small businesses. It has a visual automation builder, landing pages, a website builder, and paid newsletter subscriptions through Stripe.
It also changed a lot in June 2026. Plans were renamed Comfort and Power, prices went up across tiers, and the free plan dropped to 250 subscribers and 2,500 emails a month. Free accounts are limited to three automations with five steps each. Comfort now starts at $12 a month for 500 subscribers, and Power starts at $25.
It is still good for newsletters, but no longer the obvious free pick.
8. Omnisend
Omnisend is the main budget alternative to Klaviyo for online stores. The free plan includes automations, segmentation, and forms, with a limit of 500 emails a month. Standard starts at $16 a month, and Pro starts at $59 a month with unlimited emails.
Check SMS plans before you choose. For paid plans started on or after May 4, 2026, SMS is only available on Pro.
9. Salesforce Marketing Cloud Account Engagement
Account Engagement, formerly Pardot, handles B2B lead nurturing and lead scoring. Its biggest strength is its tight link with Salesforce CRM, so sales reps see marketing activity inside the records they already use.
Pricing starts at $1,250 per org per month. Salesforce has also added AI campaign creation through Agentforce, plus native SMS and WhatsApp. Most companies hire an implementation partner, which adds to first-year costs. Skip it unless your company already runs on Salesforce.
10. Adobe Marketo Engage
Marketo Engage is built for large B2B marketing teams. Adobe sells four packages, Growth, Select, Prime, and Ultimate, and does not publish prices. Quotes depend mainly on the size of your database.
It connects natively with Salesforce, Microsoft Dynamics, and Veeva CRM. The entry Growth package includes 10 users, while higher packages add account-based marketing, predictive audiences, and attribution. Marketo usually needs a trained admin.
How to Choose Without Wasting Money
Starting prices rarely match the final bill. Check these first:
- Count every contact. Include unsubscribed, bounced, and inactive people, since several tools bill for them.
- List your first three automations. A welcome series, abandoned cart flow, or lead nurture sequence may need a higher plan than you expect.
- Price the next tier. A $15 plan means little if the features you need start at $890.
- Decide who will run it. Enterprise tools need a dedicated admin. Small teams do better with simpler builders.

Frequently Asked Questions (FAQs)
1. What is the best marketing automation tool for small businesses?
ActiveCampaign Plus and Brevo Standard offer strong automation at low prices. If you also need a shared CRM for sales, HubSpot Starter is worth testing first.
2. Is there a free marketing automation tool?
Yes. Brevo, Omnisend, Klaviyo, and MailerLite all have free plans with some automation. Each one has tight sending or contact limits, so treat them as a trial rather than a long-term setup.
3. Which tool is best for B2B companies?
Mid-sized B2B teams usually do well with HubSpot Professional. Large companies on Salesforce often choose Account Engagement or Marketo Engage.
Final Thoughts
The best marketing automation tools are the ones that fit your list size, your team, and the flows you will actually build. For most small businesses, ActiveCampaign or Brevo covers the basics at a fair price. Online stores should compare Klaviyo and Omnisend. Larger B2B teams with a CRM already in place can look at HubSpot, Salesforce, or Marketo.
Pick two tools, start a free plan or trial, and build one real automation in each. That test will tell you more than any feature list.
