Free marketing automation tools need a closer check than a free email plan. Forms and campaigns can be free while automated sequences require payment. This shortlist separates verified limited workflows from a narrowly scoped free form-follow-up action.
| Tool | Free plan or open source | Main free-plan limit | Best for |
|---|---|---|---|
| Brevo | Free email campaigns with a daily cap; workflows support a capped automation audience. | Sending, contacts and advanced features have separate limits. | Permission-based email programs with modest usage. |
| MailerLite | Free campaigns and a small number of active automations. | Subscriber, monthly-send and workflow-step caps; trial features are separate. | Small lists and simple automated sequences. |
| HubSpot simple follow-up | One send-email action in a simple workflow per form. | This is not the full workflow editor or advanced multi-step marketing automation. | Simple opt-in form confirmation or follow-up. |

Paid tools with a free trial
ActiveCampaign and Customer.io have paid offerings or trials; Marketo is an enterprise paid product. No unsupported trial duration is asserted.
Free email is not full automation
Mailchimp Free excludes Automation Flows. Zoho Campaigns has a free email tier, but workflow access is not established as free. HubSpot permits one send-email action per form in its free simple workflow, not the full advanced workflow editor. These differences are why this page does not promise five equivalent free automation platforms.
Limits of free marketing automation tools
Contact, send and trigger caps restrict sequences. Trial features can disappear at downgrade. Check consent records, exports and upgrade costs. Test with a small permission-based sample before enabling live automation.
