Trusted by fast-moving teams
Why switch to self-hosted cold email software?
Most cold email platforms charge you for every additional mailbox or team member. As you scale from 5 to 50 inboxes, your monthly bill explodes. Linki flips this model. By choosing a self-hosted cold email software, you pay for the server, not the number of prospects or accounts.
Break free from SaaS credit anxiety
Platforms like Apollo or Instantly gatekeep your growth with credits. With Linki on Opsily, you integrate your own API keys for LLMs and enrichment. You pay only for what you actually use: no more paying for 'pro' tiers just to unlock a single feature.
Privacy that satisfies GDPR
When you use a SaaS outreach tool, your prospect data lives on their database. Linki uses a local SQLite database (linki.db) on your Opsily server. Your LinkedIn cookies, prospect lists, and campaign history stay under your control: never sold, never shared.
Powerful self-hosted cold email software on autopilot
We handle the infrastructure so you can focus on the outreach.
One-Click Deployment
Don't wrestle with Node.js 22 requirements or manual SQLite setup. Opsily configures the entire Linki self-hosted cold email software environment in 3 minutes.
Automated Backups
Your linki.db contains your entire sales engine. We perform daily encrypted backups so you never lose your campaign history or lead data.
GDPR-Ready Hosting
Hosted in Germany on enterprise-grade hardware. Your outreach platform remains compliant with strict EU data privacy standards.

EUR 800 a year for tools that used to cost us multiples of that. We replaced HubSpot, Make.com, and our password manager with self-hosted apps on Opsily. One provider, one fee.

We were paying per user on everything and it added up fast. Now we run five apps for less than one of those old plans. My finance team finally stopped asking questions.
