The best marketing automation software for small businesses
1. HubSpot Marketing Hub
HubSpot Marketing Hub consolidates marketing tools and customer data on the HubSpot CRM platform, so campaign work and customer records sit in one system rather than being synced between several. Marketing managers and coordinators in software and advertising make up most of its small business reviewers.
It holds the highest small business satisfaction score in the category, and reviewers praise beginner-friendly tools, seamless integrations and automation that streamlines workflows. Cost is the consistent criticism, with pricing that becomes hard to justify as the contact list grows and useful features sitting behind higher tiers.
2. ActiveCampaign
ActiveCampaign is a marketing platform built around goal-aware automation, orchestrating personalised journeys across email, SMS and WhatsApp with more than 1,000 app integrations. Owners and chief executives in advertising and health and wellness are its main small business reviewers, and small businesses make up the overwhelming majority of its base.
It rates second on small business satisfaction and reviewers repeatedly describe its automation as the best they have used, particularly segmentation and tagging. Setup rates lowest of these tools, and reviewers name a steep learning curve, pricing that climbs on newer plans, and limits in reporting and design flexibility.
3. Klaviyo
Klaviyo is a B2C platform that unifies marketing, analytics and customer service, capturing every click, purchase and browse into a single profile that feeds AI segmentation and timing. Owners and marketing managers in retail and advertising are its reviewers, and most come from small businesses.
It rates above the category average on building and personalising emails, A/B testing and campaign performance, and reviewers value the Shopify integration and the flow builder. Cost is the dominant criticism, described as rising with success, and reviewers report support that is slow to reach on the free plan.
4. Omnisend
Omnisend combines email, SMS and push notifications for ecommerce, with direct integrations into the major storefront platforms and pre-built automation workflows. Owners and chief executives in retail and apparel make up its reviewer base.
It rates among the highest of these tools on setup ease, ease of administration, support and likelihood to recommend, and reviewers describe getting abandoned cart and welcome flows live quickly without help. The limits they name are integration breadth, email design flexibility and SMS costs that add up faster than expected.
5. Intuit Mailchimp All-in-One Marketing Platform
Intuit Mailchimp is a marketing automation platform for personalising email and SMS at scale, with AI-powered content tools and more than 300 integrations. Owners and marketing managers in advertising and IT services are its main reviewers.
It rates above the category average on basic reporting, setup ease and building emails, and reviewers name the guided setup as what got them started. Cost is the most repeated criticism, particularly charging for unsubscribed contacts, alongside automation depth that reviewers say caps out.
6. Insider One
Insider One is an AI-native customer engagement platform with a built-in customer data platform, unifying data and journey orchestration across WhatsApp, SMS, email, web, app and site search. Digital marketing specialists and marketing managers in retail and apparel are its reviewers, and under a third of its reviews come from small businesses.
It rates highest of these tools on building and personalising emails, automated email responses, A/B testing and integration breadth, and earns the strongest support and likelihood to recommend scores of these tools. The consistent criticism is a steep learning curve driven by the number of features, with campaign setup described as time-consuming and integration work as technically demanding.
7. Attentive
Attentive is an AI marketing platform built around one-to-one SMS and email, with send-time optimisation, behaviour-triggered journeys and a dedicated customer success manager on every account. Marketing managers and directors in retail and apparel make up its reviewer base.
Reviewers describe a clean interface, quick campaign setup and onboarding support they rate highly, and it rates above the category average on A/B testing. Cost is the criticism smaller brands raise most, alongside inflexible reporting and integrations outside the standard ecommerce stack that need extra configuration.
8. Customer.io
Customer.io is a customer engagement platform for product-led teams, triggering messages across email, SMS, push, in-app and webhooks based on what users actually do rather than who they are. Chief executives and product managers in software and financial services are its reviewers.
Reviewers value a familiar interface, the flexibility of building workflows around their own data model, and support they describe as helpful. Reporting is the recurring limitation, with deeper analysis needing external tools, and several describe navigation and segmentation as harder to learn than expected.
9. HighLevel
HighLevel is an all-in-one sales and marketing platform combining CRM, email, two-way SMS, calling, funnels and scheduling, with unlimited client sub-accounts and white labelling. Owners and chief executives in advertising and consulting make up the bulk of its reviewers.
Reviewers value the breadth included at a flat rate and workflow automation triggered by almost any customer action, and it rates above the category average on workflow capability and customisation. It records the lowest small business satisfaction and setup ease of these tools, with an interface reviewers find cluttered across modules and support quality that varies.
10. EngageBay
EngageBay is an all-in-one customer engagement platform combining marketing automation, sales CRM and helpdesk, positioned as a cost-conscious alternative to the larger suites. Marketing managers and founders in IT services and staffing are its reviewers, and small businesses make up most of that base.
It rates among the highest of these tools on support, likelihood to recommend, ease of administration and automated alerts and tasks, and reviewers describe integrated automation that replaced several separate tools. Reporting is where it runs out of room, alongside limited customisation of landing pages and workflows and thin mobile functionality.
11. GetResponse
GetResponse is a lifecycle automation platform covering email, SMS, push notifications, landing pages, webinars and online courses in one system. Owners and chief executives in advertising and health and wellness are its main reviewers.
It rates among the strongest of these tools on support and likelihood to recommend, with reviewers describing prompt help and an interface that lets non-technical users build professional campaigns quickly. List sorting, report clarity and advanced feature depth are the limits they name, alongside pricing increases as lists grow.
12. Sendpilot AI
Sendpilot AI is a LinkedIn revenue platform combining lead extraction, automated outreach, AI content and a unified inbox across connected LinkedIn accounts. Founders and chief executives in advertising and IT services are its reviewers, almost entirely from small businesses.
Reviewers describe fast onboarding, automation that saves time on outreach sequences and responsive support. The limitations they name are a template library thin for niche industries, customisation that does not stretch far, and bugs in the workflow builder. It automates a single channel, so it sits alongside an email platform rather than replacing one.
13. Constant Contact Advanced Automation
Constant Contact Advanced Automation delivers multi-channel campaigns across email, SMS and social, built around pre-built automation templates and a drag-and-drop path builder. Owners and marketing managers in advertising and IT services make up its reviewer base.
It rates above the category average on analytics, data filtering and activity tracking, and reviewers value how quickly the templates get a first automation running. Customisation is the recurring criticism, with limits in branching logic and A/B testing and editing that produces inconsistent formatting.
14. LocaliQ
LocaliQ is a lead management and advertising platform from USA TODAY Co., combining AI lead scoring, automated follow-up, voice and SMS agents and managed cross-channel ad campaigns. Owners and marketing managers in advertising and software are its reviewers.
Reviewers credit responsive account teams and strategic guidance by name, and rate it above the category average on customisation and performance. Cost is the dominant criticism, described as difficult for small businesses with limited budgets, and some reviewers report results that did not match what was promised.
15. ContactPigeon
ContactPigeon is a retail customer engagement platform pairing a customer data platform with campaigns across email, SMS, WhatsApp, Viber, push, pop-ups and chatbot. Marketing managers and directors in apparel and retail make up its reviewer base.
Reviewers describe automation that handles recurring campaigns reliably and account management they rate highly, and it rates above the category average on customisation, dynamic content and data quality management. The limits are a learning curve on advanced features and slow loading on large campaign lists or segment updates.

Its small business reviewers value beginner-friendly tools, integrations that work without configuration and having marketing and customer data on one record, and it publishes a free tier with no time limit, so a team can start before committing budget.

All four are designed for self-service setup without technical help. HighLevel and ActiveCampaign rate lowest, and reviewers of both describe a learning curve that takes real time to work through.
Are there free marketing automation tools for small businesses?
There are free marketing automation tools for small businesses. HubSpot Marketing Hub, Klaviyo, Omnisend, Intuit Mailchimp All-in-One Marketing Platform, GetResponse, EngageBay and ContactPigeon all publish a free tier rather than a trial. The caps differ substantially, from 100 contacts up to 500, and monthly send limits apply on most, so the free plan that fits depends on which limit the business reaches first. ActiveCampaign, Insider One, HighLevel, Customer.io and Constant Contact Advanced Automation offer trials only, and Attentive requires a demo.
Which marketing automation software is best for an ecommerce store?
Klaviyo and Omnisend are the best marketing automation software for an ecommerce store, both built for online retail with direct storefront integrations and pre-built flows for abandoned cart, browse abandonment and post-purchase. Klaviyo suits stores wanting predictive segmentation from purchase data, and Omnisend suits smaller stores that want the same automations running sooner, rating higher on setup ease. ContactPigeon covers more messaging channels for retailers selling where WhatsApp or Viber matter.
Which marketing automation software has the best customer support?
Insider One, Omnisend, EngageBay and GetResponse have the best customer support in marketing automation, earning the strongest support scores from small business reviewers. Omnisend reviewers single out having both AI and human agents available, GetResponse reviewers describe prompt help whenever needed, and Attentive assigns a customer success manager to every account. Klaviyo rates lowest of these tools, with reviewers reporting slow responses on the free plan.
Is Klaviyo or Mailchimp better for a small business?
Whether Klaviyo or Intuit Mailchimp is better for a small business depends on how central purchase data is to the messaging. Klaviyo builds each profile from clicks, browses and orders and rates higher with small business reviewers on A/B testing and campaign performance, which suits a business selling online. Intuit Mailchimp rates higher on setup ease, basic reporting and ease of administration, and reviewers name its guided setup as what got them going, which suits a team new to automation. Both publish a free tier capped at 250 contacts.
What should a small business look out for when choosing marketing automation software?
When choosing marketing automation software, a small business should look out for how the price scales with contact count rather than the entry price, whether the automation depth holds up beyond simple sequences, how much of the reporting needs another tool, and which channels are native rather than bolted on. Cost as the list grows is the single most repeated criticism across reviews of HubSpot Marketing Hub, Klaviyo, Intuit Mailchimp, GetResponse and Attentive. Reporting depth is the recurring limit for Customer.io, EngageBay, Attentive and Constant Contact Advanced Automation. Channel coverage varies widely, from Sendpilot AI on LinkedIn alone to Klaviyo and ContactPigeon spanning six or more, so check the channels the business actually sells through are supported natively.
