TL;DR: The Best Marketing Automation Platforms at a Glance
If you want the best overall balance of price, workflow power, and breadth, ActiveCampaign is the strongest all-round pick in 2026. Its pricing page says plans start at $15 per month, the platform supports multi-step marketing automation, and ActiveCampaign says it connects with 1,000+ apps.
If you run an ecommerce brand and care more about customer profiles, product-triggered flows, and SMS tied to revenue, Klaviyo is the safer choice. Klaviyo's public pricing page shows a free plan for up to 250 active profiles, a paid email plan starting at $45 per month for 15,000 emails, and an email + mobile plan starting at $60 per month for the same email volume plus 1,250 mobile messaging credits.
For teams buying their first paid platform, the entry-price math is simple. $15 per month vs $45 per month means ActiveCampaign's starting point is $30 cheaper each month and $360 cheaper per year than Klaviyo's email-only entry plan. That does not make it universally better, but it does make it the easier default for budget-sensitive SMBs.

1. ActiveCampaign, Best Overall for SMB Automation Depth
ActiveCampaign ranks first because it covers the widest range of small and mid-size use cases without forcing most buyers into enterprise sales conversations on day one. The pricing FAQ on ActiveCampaign's own site says plans start at $15 per month, and the platform now bundles AI-assisted campaign creation, predictive sending, attribution, and cross-channel orchestration into the same product story.
The practical advantage is not just price. ActiveCampaign also says it integrates with 1,000+ apps, which matters when you want automation to connect forms, landing pages, ecommerce tools, CRM data, and messaging channels without an extra iPaaS bill.
Strengths: strong automation builder, broad app ecosystem, lower entry price, solid SMB fit.
Weaknesses: pricing page is less transparent than some rivals once contact volume rises, and ecommerce data modeling is not as retail-native as Klaviyo's.
Best for: teams of 1 to 100 that need serious automation but still care about self-serve affordability.
2. Klaviyo, Best for Ecommerce and Retail Lifecycle Marketing
Klaviyo is the clearest choice for ecommerce-first brands because its public pricing is easy to interpret and its product is built around customer profiles, catalog data, and revenue attribution. The free plan supports up to 250 active profiles, 500 monthly email sends, and 150 monthly SMS/MMS credits. Paid email starts at $45 per month for 15,000 emails, and email + mobile starts at $60 per month.
That makes Klaviyo more expensive than ActiveCampaign at the entry point, but the tradeoff is a more commerce-native data model. For Shopify, WooCommerce, and retail subscription brands, that often means faster value from browse abandonment, product recommendations, replenishment reminders, and segmented repeat-purchase flows.
Strengths: strong ecommerce segmentation, free tier, SMS and reviews add-ons, 350+ integrations.
Weaknesses: higher starting price than ActiveCampaign, cost scales with list size and messaging volume.
Best for: DTC and retail brands that want revenue-linked lifecycle marketing.
3. HubSpot Marketing Hub, Best for CRM-Centric B2B Teams
HubSpot stays on this list because many businesses do not buy marketing automation as a standalone tool. They buy it as part of a CRM stack. HubSpot's strength is that contact history, deal stages, forms, ads, and support data can all live in one operating system.
The downside is cost creep. HubSpot is easy to start with through free CRM tools, but the automation buyers actually want, like advanced workflows and reporting, usually sits on paid tiers. That makes HubSpot more compelling when your sales and service teams already live inside the platform.
4. Brevo, Best Budget Alternative for Email + SMS
Brevo remains one of the easiest alternatives for companies that want marketing automation without paying Klaviyo or HubSpot-style prices. The product combines email, SMS, basic automation, and transactional messaging in a package that usually lands below heavier rivals.
It is not as deep as Braze or Customer.io, and it is not as commerce-native as Klaviyo, but it often wins when simple lifecycle messaging matters more than advanced orchestration.
5. Omnisend, Best for Small Ecommerce Teams
Omnisend earns a place here because it focuses on ecommerce automation rather than generic small-business email. For smaller stores that want prebuilt cart, browse, welcome, and retention flows, Omnisend is often easier to launch than broader suites.
If Klaviyo feels too expensive or too broad, Omnisend is often the shortlist alternative.
6. Customer.io, Best for Product-Led Messaging
Customer.io is strongest when user behavior inside the product matters as much as classic email marketing. SaaS companies, marketplaces, and product-led growth teams often prefer it because event-triggered messaging and behavioral segmentation are central to the workflow.
Its limitation is that it is less beginner-friendly than SMB-first tools.
7. Mailchimp, Best for Familiarity and Simple Upgrades
Mailchimp still matters because millions of small businesses already know it. That lowers training cost. For simple newsletters, entry-level journeys, and basic segmentation, Mailchimp remains viable.
The issue is that advanced automation buyers often outgrow it and move to ActiveCampaign, Klaviyo, or HubSpot.
8. Braze, Best for Enterprise Cross-Channel Journeys
Braze is a serious enterprise platform for brands that need mobile push, in-app, email, SMS, and personalization at scale. It belongs near the top for capability and near the bottom for SMB accessibility because pricing is usually custom and implementation depth is higher.
For mobile-first consumer brands, though, Braze is still one of the benchmark platforms.
9. Iterable, Best for Growth Teams Running Complex Lifecycle Programs
Iterable is another enterprise-grade choice, especially for teams orchestrating multiple message types across lifecycle stages. It is often compared with Braze because both aim at sophisticated journey orchestration rather than entry-level email marketing.
Iterable becomes attractive when experimentation, audience logic, and scale matter more than a low sticker price.
10. Ortto, Best for Automation + Customer Journey Visibility
Ortto rounds out the list because it blends automation with journey visualization and customer-data workflows. That makes it interesting for B2B teams that want more than newsletter automation but are not ready for full enterprise tooling.
It is less mainstream than ActiveCampaign or HubSpot, but it covers an important middle ground.
Pricing Math: What a Small Team Actually Pays
Here are the clearest public starting points we could verify from vendor pages:
| Tool | Public Entry Plan | Annualized Cost | Notes |
|---|---|---|---|
| ActiveCampaign | Starts at $15/mo | $180/year | Trial-led, broad automation |
| Klaviyo Email | $45/mo | $540/year | 15,000 emails/month |
| Klaviyo Email + Mobile | $60/mo | $720/year | 15,000 emails + 1,250 credits |
| Klaviyo Free | $0 | $0 | Up to 250 active profiles |
That means ActiveCampaign's entry plan is $360/year cheaper than Klaviyo's email-only paid plan and $540/year cheaper than Klaviyo's email + mobile starter package. The flip side is that Klaviyo's free tier can be cheaper than both if you stay under the profile and send caps.
How We Evaluated These Tools
We weighted five criteria equally:
| Criteria | What We Measured |
|---|---|
| Pricing | Public starting price, free-tier limits, and annualized entry cost |
| Automation Depth | Multi-step workflows, branching, AI help, and behavioral triggers |
| Data Model | CRM, ecommerce events, customer profiles, and attribution |
| Integrations | Public app counts and practical ecosystem strength |
| Suitability | Whether the product fits SMBs, ecommerce, SaaS, or enterprise teams |
Pricing and feature claims were verified from vendor pages in April 2026. Review signals came from public vendor pages and DuckDuckGo snippets that surfaced live G2 result counts.

Our Recommendation
For most companies buying marketing automation in 2026, ActiveCampaign is the best place to start. The public entry price of $15 per month, the breadth of workflow features, and the 1,000+ integration claim make it the strongest default recommendation.
Choose Klaviyo instead if your business is ecommerce-first and lifecycle revenue depends on product data, repeat-purchase triggers, and SMS tied tightly to customer profiles. For that audience, Klaviyo's higher sticker price often pays back through better retail fit.
