Features
Everything you need to send cold email safely.
Mailnitrix focuses on one job: getting your emails sent from your own mailboxes without burning them. Here's everything it does, and what's coming next.
Email warmup
Your mailboxes email each other, rescue each other from spam and build reputation.
- Gradual, self-adjusting ramp
- Spam rescue and placement tracking
- Campaign cap for new mailboxes
Inbox rotation
Every campaign shared across its mailboxes, each on its own human rhythm.
- Random pacing and rolling 24-hour limits
- Error-aware cooldowns
- Automatic pause and resume
Campaigns
Import a list, personalise every line and launch on schedule.
- CSV and Excel import with duplicate controls
- Any column as a variable
- Template rotation and scheduling
Analytics
Live campaign views and open rates that count people, not proxies.
- Real-time, per-mailbox stats
- Machine opens filtered
- Tracking on or off per campaign
And much more
- Follow-up sequences that stop on reply
- One-click unsubscribe handling
- Unified inbox for every mailbox
- Shared warmup network
- Click tracking and custom tracking domains
- A/B test winner analytics
- API and webhooks
- Client workspaces for agencies
Integrations
Bring the mailboxes you already have.
Mix providers freely. Every mailbox is connected the way its provider recommends.
Privacy by default
Careful with your data.
- Mailbox passwords and Microsoft tokens are encrypted at rest
- Uploaded lead files are never stored, only the rows you import
- Warmup emails carry no tracking of any kind
- Delete leads, mailboxes or campaigns whenever you like
Every plan
Safety is never an upgrade.
- Warmup, rotation and cooldowns on the free plan too
- Rolling 24-hour limits you set per mailbox
- Campaigns that pause instead of failing, and resume on their own
- Open tracking you can switch off per campaign
