Self-hosted cold email marketing without the lead tax
Stop paying per-lead for your outreach. Run Linki on Opsily for a flat fee. Scale to unlimited contacts with hyper-personalized AI sequences on your own private server.
Why choose self-hosted cold email marketing?
Standard SaaS tools charge you more as you succeed. We provide the infrastructure for Linki so you keep 100% of your margins and maintain full data sovereignty.
No Per-Lead Tax
Legacy cold email platforms like Instantly or Lemlist charge based on your contact volume. With Linki on Opsily, your costs stay flat whether you have 1,000 or 100,000 leads in your database.
Hyper-Personalization
Utilize Linki's 3-layer AI prompt hierarchy. Customize global context, campaign rules, and individual step prompts to ensure your messages sound like a human, not a bot.
GDPR-Ready Infrastructure
Keep your prospect data on your own private server located in Germany. Data never leaves your machine, making compliance simpler than using US-based SaaS platforms.

Cold email marketing has changed.
Sending mass templates is a recipe for the spam folder. Today, success requires deep personalization and multichannel touchpoints. Linki is built for this new era.
The 3-Layer Prompt Hierarchy
Most tools use a simple 'Insert Name' tag. Linki allows you to define context at three levels:
- Global Context: Your brand voice and company mission.
- Campaign Instructions: The specific goal of this sequence.
- Step Prompts: Tailored logic for each follow-up.
Safe Multichannel Automation
Linki connects LinkedIn and Email into a single unified flow. It uses human-like pacing, random delays, and browser-cookie authentication. This mimics real human behavior, protecting your reputation while you scale.
Native Enrichment
Connect your Apollo.io API or use OpenRouter to access models like Claude 3.5 or GPT-4o. You choose the brains behind your outreach without being locked into a single provider's expensive credit system.
