Mautic
open sourceGPL-3.0+Self-host10kaug 2026The full automation engine with no contact tax; it replaces the SaaS bill with serious server maintenance.
The catch vs ActiveCampaignMautic can match deep automation, but the user must operate the application, database, cron, upgrades, backups, mail transport, and deliverability stack.
Install, platforms & data +
- platforms
- webself-hostedself-host, real ops
- install
- Download the production package or install with Composer, then configure PHP, a database, cron, and a mail transport
- setup
- 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.
- your data
- Contacts, segments, campaigns, events, and reports live in the configured MySQL or MariaDB database; assets, configuration, logs, and queue files live on the server filesystem.

Plunk
open sourceAGPL-3.0Local or hosted5.3kaug 2026Campaigns, transactional mail and workflows in one container; the sending provider still sends a bill.
The catch vs ActiveCampaignPlunk is developer-first and much thinner in visual audience management, CRM depth, segmentation tooling, and marketer-oriented reporting.
Install, platforms & data +
- platforms
- webself-hosteddocker to self-host
- install
- Hosted signup, or the official Docker Compose stack
- setup
- 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.
- your data
- The 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.

Notifuse
open sourceAGPL-3.0Local or hosted2.0kaug 2026Visual campaigns and automations in one modern compose stack; PostgreSQL and an SMTP provider still need seats.
The catch vs ActiveCampaignNotifuse is newer and narrower, without ActiveCampaign's mature CRM, predictive features, and thousand-plus integration ecosystem.
Install, platforms & data +
- platforms
- webself-hosteddocker to self-host
- install
- Hosted signup, or one application container plus PostgreSQL for self-hosting
- setup
- Self-hosting still needs Docker, PostgreSQL, a public HTTPS endpoint, an SMTP or API sending provider, and correctly authenticated sending domains.
- your data
- Self-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.

Brevo Free
freeproprietary, freeHostedCampaigns and automation for up to 2,000 automated contacts; the 300-email daily ceiling slows launch day.
The catch vs ActiveCampaignThe 300-email daily limit can split even a small launch across days, and only 2,000 contacts can enter automations on the free plan.
Install, platforms & data +
- platforms
- webthey host it
- install
- Hosted signup, sender verification, and optional domain authentication
- setup
- The first meaningful hurdle is verifying the sender and setting SPF/DKIM records for a sending domain; without that, deliverability will disappoint.
- your data
- Contacts, campaigns, templates, automation events, and reports live in Brevo's cloud; exports are available, but the internal storage format is not disclosed.

EmailOctopus Free
freeproprietary, freeHostedA useful hosted list plus three five-step automations; exactly enough machinery for a small lifecycle.
The catch vs ActiveCampaignIts automations are intentionally lightweight and do not approach ActiveCampaign's branching logic, goals, CRM integrations, or sales workflows.
Install, platforms & data +
- platforms
- webthey host it
- install
- Hosted signup, list import, and sender/domain verification
- setup
- A sender address must be verified, and serious sending should use an authenticated domain.

Loops Free
freeproprietary, freeHostedLifecycle and marketing email for 1,000 contacts with every feature; contact 1,001 brings a card reader.
The catch vs ActiveCampaignLoops 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.
Install, platforms & data +
- platforms
- webthey host it
- install
- Hosted signup, domain authentication, and event/API integration for lifecycle email
- setup
- 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.
- your data
- Contacts, events, templates, and campaign or loop state live in Loops's cloud; the internal storage format is not disclosed.
- checked

- 07
Sender Free
freeproprietary, freeHostedA real free list, unlimited workflows and 15,000 monthly sends; SMS did not make the cut.
The catch vs ActiveCampaignSender covers email automation but not ActiveCampaign's sales CRM, deal records, lead scoring, or broad sales-automation layer.
Install, platforms & data +
- platforms
- webthey host it
- install
- Hosted signup, list import, and sender/domain verification
- setup
- The first real hurdle is authenticating the sending domain and warming a legitimate list rather than merely creating the account.

For ActiveCampaign, run a small email list and a handful of transparent automations. The hard boundary is deep lifecycle automation, crm, deliverability, integrations, and data history, plus deliverability, growth network, and integrations.
