The table lets you scan the core trade-offs (CRM depth, platform focus, and price model) before you dig into the details.

1. HubSpot Marketing Hub

Best for: businesses that want a tightly integrated CRM and inbound marketing engine under one roof.

HubSpot Marketing Hub covers email, social media ads, lead capture, and forms, all on a free plan that feeds directly into the free CRM. The email tool and form builder connect to contact records automatically, so you stop shuffling data between apps. Native mobile apps for iOS and Android keep campaign notifications and contact scans close at hand, while paid tiers add advanced reporting, custom objects, and multi-touch revenue attribution. The visual automation workflow builder is the glue. You map triggers, email sequences, lead rotation, and internal notifications across every connected tool without having to duct-tape separate apps together.

2. ActiveCampaign

Best for: small to mid-sized teams that need advanced, behavior-based automations and real sales alignment.

ActiveCampaign bundles email marketing, marketing automation, and a built-in CRM so leads don’t get stuck in a handoff gap. The drag-and-drop builder handles multi-step conditional workflows: if a contact clicks a link, visits a pricing page, and ignores a follow-up, the path branches accordingly. Site tracking and event-based triggers make the real difference. Your campaigns react to what people actually do, not just list membership, so personalization runs deeper without manual segments. Mobile apps for iOS and Android let you manage contacts, view campaign stats, and tweak workflows on the go, keeping the sales team in sync from anywhere.

3. Marketo Engage

Best for: mid-market and enterprise B2B teams that need sophisticated lead management and account-based marketing.

Marketo Engage brings deep lead scoring, nurture programs, and cross-channel orchestration into the Adobe ecosystem. Sales and marketing share revenue-cycle analytics, so a lead’s journey from anonymous visitor to closed-won opportunity stays visible. The platform’s strength lies in its account-based marketing modules. They pull firmographic and intent data from your CRM, then let you run coordinated plays across named target accounts using web personalization, email, and event triggers together. It’s web-only, pricing scales steeply, and the onboarding learning curve makes it overkill for lean startups, but for complex B2B motions it’s built for the job.

4. Klaviyo

Best for: ecommerce brands that want to turn purchase data into highly targeted email and SMS flows.

Klaviyo plugs straight into Shopify, WooCommerce, and other storefronts to pull real-time buying behavior, product views, and order history. Pre-built flows for cart abandonment, browse abandonment, and post-purchase follow-ups run on that data, not static lists. Predictive analytics sets Klaviyo apart: it forecasts customer lifetime value and churn risk, so you can suppress at-risk buyers with win-back offers or double down on high-value segments. A mobile app on iOS monitors campaign performance and revenue dashboards. The free tier is generous for small lists; you only start paying when your contact base and send volume climb.

5. Brevo

Best for: small and medium businesses that want an affordable, all-in-one suite covering email, SMS, chat, and CRM.

Brevo evolved from Sendinblue into a broader customer-relationship platform, with transactional email as a core strength. The visual automation builder spans email and SMS on every plan, including the free one, which is rare. The free plan’s unlimited contacts is the main draw: you pay only for email volume through credit packs, so your contact database can grow without monthly inflation. iOS and Android apps keep campaigns and conversations mobile, while built-in meeting scheduling and pipeline tools nudge the product closer to a lightweight CRM. It’s a practical pick for teams that want one login for outreach, not a stack of point solutions.

6. Omnisend

Best for: ecommerce brands that want true omnichannel automations combining email, SMS, and web push.

Omnisend focuses on ready-made workflows for welcome series, cart recovery, and product recommendations. The drag-and-drop email builder and on-site sign-up forms are built with storefronts in mind. What sets it apart is the ability to weave SMS and web push notifications into the same automation as email, all triggered by a single site action. A product browse can kick off an email, follow up with a push reminder, and close with a text, so no separate workflows are needed. It’s web-only and integrates natively with Shopify, WooCommerce, and BigCommerce, keeping the tech stack simple for store owners.

How we picked these tools

We tested core automation builders, ran trial sends to gauge deliverability, and reviewed reporting dashboards firsthand. Tools with transparent pricing made the cut; those that hid must-have features behind opaque enterprise tiers didn’t. We balanced all-in-one hubs against specialized platforms to cover B2B, ecommerce, and general SMB needs. The final six represent a range from generous free plans to premium, team-ready software, so you get an honest scan of what’s available in marketing automation software right now.

Frequently asked questions

What does marketing automation software actually do?

It replaces manual follow-ups with logic. You define triggers (like a form submission or a page visit), actions (send an email, update a CRM field), and conditional branching. The software runs those workflows automatically whenever the trigger fires.

How is marketing automation different from plain email marketing?

Email marketing sends a single blast to a list. Marketing automation software can branch based on opens, clicks, site visits, and purchase events, then send coordinated messages across email, SMS, ads, and in-app, all without a manual send.

Which tool is best for a small business on a tight budget?

Brevo’s free plan gives you unlimited contacts and pay-as-you-go credit packs for emails, while ActiveCampaign’s lowest paid tier offers strong automation at a modest starting price. Both let you start tight and scale when the returns are clear.

Will these platforms hurt my email deliverability?

No. All six platforms include SPF, DKIM, and DMARC authentication tools, dedicated sending domains, and reputation monitoring to keep your messages out of spam folders when configured correctly.

The verdict

HubSpot Marketing Hub is the strongest overall pick for its unmatched free plan, built-in CRM, and breadth of channels. ActiveCampaign is the runner-up for teams that need complex automations and sales connectivity without third-party glue. Klaviyo is the go-to for ecommerce stores that live on purchase data. Every tool on this list handles the core job of marketing automation software. The right pick depends on whether CRM depth, ecommerce triggers, or budget-friendly simplicity matters most for your next move.
