Frequently Asked Questions

How long does setup take?

Fresh install: 1-3 days (mostly waiting on your DNS/SMTP access). Migration: 1-3 weeks depending on complexity. Your old tools stay live the entire time.

Can I migrate from my current tools?

Yes. We export your contacts, rebuild key email templates, and recreate your automations in the new stack. The cutover happens over one weekend — Monday morning, your team logs into the new system.

What's included in the monthly fee?

EU-hosted VPS, daily backups, security updates, SSL certificates, SMTP deliverability monitoring, dedicated support, and ongoing maintenance. One flat fee, no surprise invoices.

Is my data safe?

Yes. Your stack runs on EU infrastructure with daily backups. We manage security updates and SSL certificates. You own the data; we manage the pipes.

Can I add users?

Unlimited users. Unlike paid tools that charge per user, our stack has no user limits. Bring your whole team.

What happens if I leave?

You keep everything. We hand over the Docker containers, databases, and credentials. No lock-in. No ransom.

Why open-source?

Open source means you own your data, avoid vendor lock-in, and never face surprise price hikes. No contact limits, no email send caps, no per-user fees. Learn more →
