Free alternatives to ActiveCampaign

Campaigns and automation for up to 2,000 automated contacts; the 300-email daily ceiling slows launch day.

Versus paying: The 300-email daily limit can split even a small launch across days, and only 2,000 contacts can enter automations on the free plan.

Setup: Hosted signup, sender verification, and optional domain authentication

Watch for: The first meaningful hurdle is verifying the sender and setting SPF/DKIM records for a sending domain; without that, deliverability will disappoint.

A useful hosted list plus three five-step automations; exactly enough machinery for a small lifecycle.

Versus paying: Its automations are intentionally lightweight and do not approach ActiveCampaign's branching logic, goals, CRM integrations, or sales workflows.

Setup: Hosted signup, list import, and sender/domain verification

Watch for: A sender address must be verified, and serious sending should use an authenticated domain.

Lifecycle and marketing email for 1,000 contacts with every feature; contact 1,001 brings a card reader.

Versus paying: Loops is an email-lifecycle tool rather than a sales-and-marketing CRM, so it does not replace ActiveCampaign's deal, account, and broad automation ecosystem.

Setup: Hosted signup, domain authentication, and event/API integration for lifecycle email

Watch for: Marketing broadcasts are easy, but lifecycle automation becomes useful only after a non-expert authenticates a domain and connects product events through an integration or API.

The full automation engine with no contact tax; it replaces the SaaS bill with serious server maintenance.

Versus paying: Mautic can match deep automation, but the user must operate the application, database, cron, upgrades, backups, mail transport, and deliverability stack.

Setup: Download the production package or install with Composer, then configure PHP, a database, cron, and a mail transport

Watch for: The first wall is not the installer but production operation: PHP and database tuning, several cron jobs, HTTPS, backups, upgrades, SMTP/API sending, and DNS authentication.

Visual campaigns and automations in one modern compose stack; PostgreSQL and an SMTP provider still need seats.

Versus paying: Notifuse is newer and narrower, without ActiveCampaign's mature CRM, predictive features, and thousand-plus integration ecosystem.

Setup: Hosted signup, or one application container plus PostgreSQL for self-hosting

Watch for: Self-hosting still needs Docker, PostgreSQL, a public HTTPS endpoint, an SMTP or API sending provider, and correctly authenticated sending domains.

2,038 GitHub stars (checked Aug 6, 2026)

Campaigns, transactional mail and workflows in one container; the sending provider still sends a bill.

Versus paying: Plunk is developer-first and much thinner in visual audience management, CRM depth, segmentation tooling, and marketer-oriented reporting.

Setup: Hosted signup, or the official Docker Compose stack

Watch for: Hosted use still needs domain authentication; self-hosting adds PostgreSQL, Redis, MinIO, Nginx or another proxy, exposed web and SMTP services, DNS, and ongoing deliverability work.

5,300 GitHub stars (checked Aug 6, 2026)

A real free list, unlimited workflows and 15,000 monthly sends; SMS did not make the cut.

Versus paying: Sender covers email automation but not ActiveCampaign's sales CRM, deal records, lead scoring, or broad sales-automation layer.

Setup: Hosted signup, list import, and sender/domain verification

Watch for: The first real hurdle is authenticating the sending domain and warming a legitimate list rather than merely creating the account.
