Every email is unique.
Every inbox is reached.

Subject rotation, body variants, spintax, and smart sender cycling guarantee no two emails are the same. Spam filters never see a pattern.

Subject Line Rotation

Rotate multiple subjects with variables & spintax

A: "Quick question about {{company}}"
B: "{{firstName}}, saw your latest post"
C: "Idea for {{company}}'s outreach"

Smart Sender Rotation

Health-weighted, per-domain throttling

sarah@outreach.io 50/day
mike@growth.co 30/day
jen@pipeline.dev 50/day

Nested Spintax

Infinite variations per send

{Hey|Hi|Hello} {{firstName}},

{I noticed|Saw that|Looks like} {{company}} is {scaling|growing|expanding}...

27 unique combinations from this template alone

Body Variant Rotation

A/B test multiple email bodies per campaign

Variant A 32% reply rate
Variant B 18% reply rate
Variant C 24% reply rate

Result: Zero pattern detection

Every email looks hand-typed. Spam filters see unique messages, not bulk sends.

Lead Intelligence

Clean your lists before you send.

Built-in list hygiene engine — 135,000+ disposable domains, syntax checks, MX verification, role account detection, and typo correction. Removes junk before you send. For SMTP-level deliverability verification, pair with a dedicated service like MillionVerifier.

135K+ Disposable Domains — Spam traps, temp inboxes, and throwaway providers caught instantly
Reply Detection — IMAP every 2 min. Genuine vs OOO vs auto.
Bounce Intelligence — Hard/soft, cross-list invalidation
Auto-Pause — Blacklist monitor, cooldown, reputation guard

△️ Note: Due to Port 25 restrictions on most VPS providers, SMTP handshake verification is not possible. We recommend verifying leads externally (MillionVerifier, ZeroBounce) for better deliverability before importing.

No. Installation takes about 5 minutes — run one command on your VPS and you’re live. If you’d rather not touch the terminal, we offer a done-for-you setup for a one-time $9 fee. We’ll deploy everything and hand you a working system.
Any SMTP provider. Gmail, Outlook, AWS SES, SendGrid, Zoho, Resend, or any custom SMTP. You buy your own sending infrastructure and plug it into Cleanmails. The platform handles rotation, scheduling, and throttling across all connected mailboxes. No vendor lock-in.
Built-in and fully automated. The warmup engine gradually increases sending volume from 2 emails/day to 30/day over 30 days. It generates realistic email conversations with auto-replies to build your domain reputation organically. No third-party warmup tool needed. Just enable it per mailbox from the dashboard.
A basic Linux VPS — Hetzner, Contabo, or DigitalOcean at $6–10/month handles thousands of emails daily. No special requirements, no Docker, no Node.js. Cleanmails is a single compiled binary. Connect your SMTP providers and you’re ready to send.
Truly unlimited. No contact limits, no email limits, no domain limits, no sender limits, no workspace limits. The only limit is your server’s capacity and your SMTP provider’s daily allowances — which on a standard setup is massive. Add 100 clients tomorrow and pay $0 extra.
When a prospect replies, the AI reads the message, classifies intent (interested, question, objection, not interested), and drafts a contextual reply using your campaign knowledge base. You can approve each reply manually or enable full autopilot. Supports 10+ AI providers — bring your own API key at ~$0.001/reply. No credits system, no markup.
Yes. Mix and match — Gmail for some domains, AWS SES for others, SendGrid for high-volume. The smart rotation engine distributes sends across all connected mailboxes based on health, daily limits, and domain reputation. Round-robin with auto-cooldown.
The standard license ($199) lets you run campaigns for unlimited clients under your brand. The Enterprise/SaaS license ($997) gives you full source code access and commercial resell rights — build your own SaaS platform, charge monthly, keep 100% of revenue.
We cannot access your data. Period. Cleanmails runs entirely on your server. No cloud dependency, no phone-home, no telemetry. Your leads, campaigns, and reply data are encrypted at rest with AES-256 and never leave your machine. You own everything.
14-day money-back guarantee. If Cleanmails doesn’t work for your use case, email us within 14 days and we’ll refund you in full. No questions, no hoops.
You get the software forever — plus all future updates free. Updates are one-click from the dashboard. No maintenance plans, no renewal fees. New features ship regularly and you get them all. The warmup engine is already included and running.
Join our Discord community where the dev team and other agency owners help in real-time. We also provide documentation and priority support for Enterprise license holders. You’re never left alone.
