Sendy
SMBSelf-hosted email marketing application that sends via Amazon SES to reduce delivery costs.
REST API plus webhooks let external systems trigger sends and receive delivery and engagement events.
Sendy uses a MySQL backed data store for lists, subscribers, and send jobs, which keeps operational data under the same administrative boundary as the rest of the stack. Send execution supports CSV import for recipient onboarding and webform lead capture for signup traffic, with double opt-in workflow support to reduce spam complaints. Send tracking includes open rate tracking and click-through attribution so downstream reporting can be driven by Sendy event logs.
A key tradeoff is that Sendy is not a full marketing automation suite, so multi-step journeys, branching logic, and CRM synchronization need external workflows. It fits teams that already manage segmentation and timing outside Sendy and only need reliable sending, deliverability signals, and API driven integration. It also fits operations that can own sender reputation processes like DKIM signing, SPF alignment, and DMARC enforcement across sending domains.
- +Self hosted SMTP relay model keeps sending under direct infrastructure control
- +Queue throttling supports predictable throughput during large sends
- +REST API and webhooks connect send jobs to internal systems
- +Built-in open tracking and click attribution support actionable reporting
- –Deliverability requires disciplined sender authentication setup and ongoing monitoring
- –Advanced journey automation needs external orchestration
- –Segmentation and targeting depend on list operations rather than built-in AI
- –Higher volumes increase operational burden on mail infrastructure and queue tuning

Mailwizz
enterpriseSelf-hosted email marketing application designed for agencies and multi-tenant SaaS operations.
REST API endpoints for subscriber provisioning and campaign management from external systems.
Mailwizz targets teams that want to run email operations inside their own environment while keeping campaign management features in one place. Campaign execution supports batch sending, queue behavior tied to cron-driven processing, and reusable templates for repeatable newsletter workflows. Tracking covers opens and click-through behavior, with reporting views that group performance by campaign and segment selections.
The main tradeoff is operational overhead, because Mailwizz depends on correct server setup for SMTP relays, DNS configuration, and ongoing bounce processing. It fits best when an organization already has at least one person managing mail server configuration and wants the ability to integrate sending and subscriber provisioning with internal tooling.
- +Self hosted campaign execution with cron-driven queue processing control
- +Subscriber lifecycle states with bounce handling for list hygiene
- +API access for subscriber provisioning and campaign automation
- +Segment-based targeting with reusable templates for recurring newsletters
- –Requires disciplined configuration of SMTP relay and DNS authentication
- –Automation builder is limited compared with full marketing workflow suites
- –Reporting is strongest for opens and clicks, not deep attribution
- –Upgrades can be operationally heavy when customizing server components

Best for: Fits when teams need self hosted sending, internal integrations, and controlled queue execution.
SendPortal
SMBOpen-source self-hosted email marketing platform built with Laravel and Vue.
Webhook-driven event delivery that turns sending status and tracking signals into external workflows.
SendPortal fits teams that want self-hosted control over the sending stack rather than relying on a hosted ESP. Campaigns run against imported contacts and segmented audiences, and delivery can be governed through explicit sending configuration and domain authentication settings. Event handling is central for operations, with webhook notifications for downstream automation and a REST API for programmatic campaign and list workflows. The system also includes configuration hooks that support unsubscribe handling behavior and tracking for opens and clicks.
A key tradeoff is operational overhead, because deliverability and throughput depend on correct DNS and sending host configuration. SendPortal works best when an internal platform team can maintain the SMTP relay, DNS records, and suppression rules so marketing teams can focus on audience and campaign design.
- +Self-hosted sending control with explicit delivery configuration
- +REST API supports campaign automation and list management workflows
- +Webhook event delivery enables external orchestration for marketing ops
- +Built-in domain authentication controls include DKIM signing

How to Choose the Right self hosted email marketing software
Self hosted email marketing software is built so sending, tracking, and subscriber operations run on an organization’s own infrastructure, not a hosted marketing platform. This buyer’s guide covers Sendy, Mailwizz, SendPortal, FluentCRM, AcyMailing, phpList, Mautic, Interspire Email Marketer, Octeth Oempro, and Mailcoach.
Tool selection hinges on where control lives, since Sendy and Mailwizz center REST API and queue execution control, while Mautic and FluentCRM lean into workflow orchestration inside the app. Admin and governance expectations also differ, because phpList uses list-centric event handling while Interspire Email Marketer focuses on extensibility and custom integration hooks.
Self hosted email marketing software for controlled sending, tracking, and automation
Self hosted email marketing software manages subscriber lists, campaign sends, and engagement tracking inside a self deployed system, with SMTP relay and DNS configuration forming the delivery baseline. Systems like Sendy and Mailwizz emphasize external orchestration via REST API and webhooks, including delivery and engagement event flows for downstream systems.
Automation depth varies by product architecture, since Mautic provides visual, branching journeys that can call out to external actions through API integrations, while FluentCRM ties automation triggers to WordPress events and subscriber status changes in the same admin model. Operations also differ in queue execution control, because Sendy and Mailwizz support cron-driven or queue managed sending to keep throughput predictable during larger sends.
Integration and automation surfaces for self-hosted email workflows
Self hosted email marketing software succeeds when the sending and tracking events can flow into the rest of the organization through documented integration points. REST API access, webhooks, and event payloads decide whether campaigns stay inside the app or become part of broader product, CRM, and data pipelines.

Decide where orchestration lives and how much governance is acceptable
Choose based on where the workflow engine should run. Sendy and Mailwizz align with external orchestration because they emphasize REST API control and queue execution management, while Mautic and FluentCRM align with in-app orchestration through journeys or WordPress-triggered automation.
Pick the orchestration philosophy: in-app journeys versus external workflow engines
Select Mautic when branching campaign journeys must be authored and debugged inside the self-hosted admin and when external actions can be invoked from those journeys through API-driven integrations. Select Sendy or Mailwizz when sends and lifecycle actions must be orchestrated by external systems through REST API control and outbound tracking events.
Lock in an integration contract for events you must react to
Choose Sendy or SendPortal when delivery and engagement signals must be pushed to external systems through webhooks. Choose Mailwizz or Mailcoach when the organization needs REST API endpoints to manage subscriber and campaign operations programmatically.
Plan throughput control for large campaign windows
Choose Sendy when throughput predictability during large sends depends on Queue throttling combined with direct infrastructure control via a self hosted SMTP relay model. Choose Mailwizz when campaign execution timing depends on cron-driven queue processing control.
Map triggers to your source of truth instead of forcing data into the wrong workflow
Choose FluentCRM when WordPress is the system of record and automation must react to membership, form, and status changes using WordPress event integration in the same admin model. Choose phpList when unsubscribe and bounce handling should be tied to subscriber records through built-in list-centric event handling.
Validate that automation depth matches operational maintenance capacity
Choose AcyMailing when lifecycle messaging must react to subscriber events and list membership changes through multi-step automation workflows. Choose Interspire Email Marketer when custom provisioning and automation flows depend on extensibility hooks and developer access, but accept that automation depth can be more limited than workflow-first tools.
Teams that match self-hosted requirements and operational expectations
Self hosted email marketing software fits organizations that need infrastructure control for sending and tracking. It also fits teams that must integrate email behavior into internal systems through REST API operations and event delivery mechanisms.
Platform and product teams integrating email into app workflows
Sendy fits teams that need API-triggered sends plus webhooks for delivery and engagement events so product and data systems can react in near real time. SendPortal fits teams that need webhook-driven event delivery to drive external automation around sending status.
Marketing ops teams managing predictable campaign execution windows
Mailwizz fits teams that want cron-driven queue processing control so sending execution can be scheduled and throttled via infrastructure-managed jobs. Sendy fits teams that need Queue throttling for predictable throughput under direct infrastructure control.
WordPress-centric organizations that want automation tied to membership and forms
FluentCRM fits organizations that run member onboarding and status changes in WordPress and want automation keyed off WordPress triggers inside the same admin model. Mautic fits organizations that want visual branching journeys that can also call external actions when those triggers originate outside WordPress.
Operations-focused teams that prioritize list hygiene and subscriber state events
phpList fits teams that want built-in unsubscribe, bounce processing, and suppression tied to subscriber records for steady newsletter operations. AcyMailing fits teams that want automation to react to subscriber events and list membership changes in multi-step lifecycle messaging.
Common self-hosted email marketing mistakes that break sending and automation
Self hosted deployments fail when deliverability requirements are treated as a one-time setup or when automation triggers are mapped to the wrong source events. They also fail when external integrations assume delivery and engagement signals exist without defining the event and payload flow.
Building workflows on an API integration but ignoring webhook or event payload availability
Sendy and SendPortal expose webhooks for sending status and tracking events, so external workflows should be designed around those signals rather than polling for state.
Assuming campaign execution will naturally stay stable during large sends
Sendy uses Queue throttling and Mailwizz uses cron-driven queue processing control, so throughput controls must be configured as part of launch readiness.
Using in-app automation without validating trigger mapping and event correctness
FluentCRM automation depends on correct WordPress triggers and event mapping, and Mautic journey debugging gets slower when complex journeys require deep event tracing.
Treating deliverability configuration as optional operational overhead
Sendy, Mailwizz, and SendPortal all require disciplined SMTP relay and DNS authentication setup for deliverability, and phpList and Mautic also depend on correct email sending configuration for stable outcomes.
Overestimating automation depth when the workflow engine is not the product’s center
Interspire Email Marketer and Octeth Oempro emphasize extensibility or template authoring, so workflow-first expectations can lead to workflow workarounds instead of native journeys.
