Cleanmails
Runs cold email campaigns, list cleaning, sender rotation, and cadences from your own server with no monthly fee.

This platform is built for founders, agencies, and builders who want to run outbound email from infrastructure they control instead of paying a recurring fee for a hosted platform. It brings campaign sending, list cleaning, sender rotation, warmup, and reply handling into one self-hosted setup.
The platform is designed for outbound campaigns that need more than basic mail merging. Users can create multi-step sequences, schedule follow-ups, and manage campaigns from a central dashboard. Unlimited mailboxes and sender rotation are included, allowing teams to distribute sending across multiple accounts without per-seat pricing.
Key Features
Campaign Sender
Create and manage automated cold email campaigns.
The platform supports:
- Multi-step sequences
- Automated follow-ups
- Scheduled cadences
- Campaign management
- Automated sending
This allows teams to keep outreach running without manually sending each follow-up.
Smart Variants
Create variation across outbound messages.
The system can rotate subject lines, modify sentences, and shuffle senders so recipients receive different versions of campaign messages. This is designed to add variation across larger outbound campaigns.
MCP and AI Control
Connect AI agents to outbound workflows.
AI can be used for tasks such as:
- Reply handling
- Campaign pauses
- Sending decisions
- Workflow actions
This gives teams the ability to incorporate AI into their outreach process rather than treating email sending as a completely separate workflow.
SMTP and Warmup
Connect existing email infrastructure and prepare senders for outbound activity.
The platform works with SMTP providers and AWS SES, while automatically warming up connected senders. This allows teams to use infrastructure they already control instead of being locked into a specific sending provider.
Unified Inbox
Manage replies from multiple mailboxes in one place.
Instead of checking individual accounts, teams can bring replies from connected senders into a single inbox and manage conversations from the same dashboard used for campaigns.
Health Metrics
Monitor signals related to outbound email performance.
The platform provides visibility into areas such as:
- Deliverability
- Sender reputation
- Domain health
These metrics help teams keep track of the health of their outbound infrastructure.

Why It Matters
Hosted cold email platforms can make outbound easier to launch, but they also mean relying on someone else's infrastructure and recurring pricing model. This platform takes a different approach by allowing users to run their outreach system on infrastructure they control.
The self-hosted setup gives teams ownership over their data and infrastructure, while the one-time license removes the need for a traditional monthly platform fee. The system combines the main components of outbound operations, including sending, warmup, sender rotation, inbox management, and AI-assisted reply handling.
It is also designed for agencies and businesses that need to manage outreach for multiple clients. Unlimited client workspaces and white-label branding allow the platform to be presented as part of an agency's own service. A separate source code license is available for teams that want to rebrand and resell the software as their own SaaS.
The main appeal is the combination of control and breadth. Instead of paying for separate tools for sending, warmup, inbox management, and AI-assisted outreach, teams can run these functions from one self-hosted system.
Run Cold Outreach on Infrastructure You Control
Set up campaigns, rotate unlimited mailboxes, warm up senders, manage replies, and connect AI agents from a self-hosted cold email platform. A one-time license provides the core system, with lifetime updates and options for agencies that need client workspaces or white-label deployment.
