ProMailer is a local-first, highly deliverable cold outreach workstation built for solo founders, builders, and agency operators. Run 100% locally on your own desktop hardware with complete sovereignty over your data and pipelines.
Most cold outreach tools log your pipelines, track your activity, and extract premium monthly fees. ProMailer operates locally under your direct supervision.
Plaintext passwords, API keys, and sensitive campaign lead documents remain locked on your own hardware. Your prospect data is never shared, parsed, or used for cloud training.
By compiling hyper-clean, spam-proof plaintext layouts, ProMailer completely bypasses marketing filters. Your letters land directly in primary text folders with zero tracking-pixel bloat.
Stop paying ongoing monthly subscriptions to middleman platforms. Pay once, download your platform executable package, and execute campaigns forever with zero ongoing license fees.
Engineering features focused entirely on performance, compliance, and solo founder ease of use.
Configure seamless switches between absolute private local execution (Ollama) and high-fidelity cloud fallbacks (OpenAI, Anthropic) via the setup wizard.
Automatically crawls target prospect websites on-the-fly to pull business service lines, cities, and context prior to composing personalized campaigns.
Integrated secure IMAP inbox checks continually scan for incoming replies. Once a response is detected, the lead is paused instantly, prompting manual inbox handoff.
An interactive command-line setup wizard validates email SMTP parameters and API keys, and auto-locks written config structures under robust file permissions (chmod 600).
Launch a premium glassmorphic local-host dashboard (localhost:5050) to monitor real-time queue lengths, performance metrics, and detailed campaign inspections.
Strict daily campaign pacing limit (max 20 emails/day) and auto-cool-down gaps (4 minutes) between messages preserve your domain's health and security.
One single, low-cost purchase gives you full access to all three platform versions. Zero ongoing licenses, yours forever.
