Mautic

open sourcewebself-hostedself-host, real ops

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

licenseGPL-3.0+

runsyour server

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

dataContacts, segments, campaigns, events, and reports live in the configured MySQL or MariaDB database; assets, configuration, logs, and queue files live on the server filesystem.

the catch vs ActiveCampaignMautic can match deep automation, but the user must operate the application, database, cron, upgrades, backups, mail transport, and deliverability stack.

setupThe 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.

P

Plunk

open sourcewebself-hosteddocker to self-host

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

licenseAGPL-3.0

runsyour machine or their cloud

installHosted signup, or the official Docker Compose stack

dataThe self-hosted stack stores core data in PostgreSQL, jobs and cache in Redis, and objects in MinIO; hosted data is kept in Plunk's EU infrastructure.

the catch vs ActiveCampaignPlunk is developer-first and much thinner in visual audience management, CRM depth, segmentation tooling, and marketer-oriented reporting.

setupHosted 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.

N

Notifuse

open sourcewebself-hosteddocker to self-host

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

licenseAGPL-3.0

runsyour machine or their cloud

installHosted signup, or one application container plus PostgreSQL for self-hosting

dataSelf-hosted contacts, campaigns, automations, and events live in PostgreSQL; files can use S3-compatible storage, and the configured email provider receives message payloads. Hosted data lives in Notifuse's cloud.

the catch vs ActiveCampaignNotifuse is newer and narrower, without ActiveCampaign's mature CRM, predictive features, and thousand-plus integration ecosystem.

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

how to choose a ActiveCampaign alternative

Easiest to get running

Listmonk — a one-click install, no server to maintain.

Most proven

Ghost, with 49,000 GitHub stars — the largest community of the 6, which usually means more answers when something breaks.

Needs real ops to self-host

Mautic is capable but expects someone to run a server, updates and backups. Budget for that before choosing it.

why people still pay for ActiveCampaign

People still pay for ActiveCampaign because newsletter operators pay for inbox placement, growth mechanics, and operational confidence on publication day. The recurring cost buys DNS authentication, reputation, bounces, complaints, unsubscribe compliance, templates, queues, analytics, backups, and support, not just the visible interface. If none of that applies to you, any pick above saves $180 a year.
