Klaviyo Alternative: Unlimited Email, Flat-Fee Hosting
Klaviyo charges per contact. Your list grows faster than your campaigns. You overpay. Listmonk cuts the cost: no per-contact fees, unlimited sending, flat monthly price. Self-hosted on Opsily infrastructure. GDPR-compliant German data centers. Own your email data.
Why Listmonk on Opsily
The email marketing platform built for founders tired of SaaS.
No Per-Contact Fees
Klaviyo charges by subscriber count. So does Omnisend. Listmonk doesn't. Host 10,000 contacts or 1 million—same flat fee. Your list grows, your cost stays the same. No surprise overages when you import customer data.
GDPR Data Residency
Self-hosted in German data centers. Your email data never touches US cloud infrastructure. No GDPR transfers. No legal friction with EU customer lists. Own the servers, control the data.
Own Your Data
Export contacts anytime in bulk. No API rate limits. No export fees. Open-source code means you can fork it, modify it, or migrate away with zero friction. With Klaviyo, migration is a 3-month project.
Built for teams who need reliability
Omnisend vs. Listmonk on Opsily
Omnisend ranks #1 in every 'Klaviyo alternative' guide. Here's why Listmonk still wins.
Pricing and features as of October 2026. Omnisend's 35% savings claim vs. Klaviyo assumes you switch both pricing models.
The Contact-Based Pricing Trap
Klaviyo works great until your subscriber list grows. Then the math breaks.
You have 50,000 contacts. You send 2 campaigns per month. Klaviyo charges you as if you run daily broadcasts to all of them.
Meanwhile, a competitor uses Brevo (send-volume based) and pays less. But Brevo is still SaaS. Still vendor lock-in. Still someone else's servers, someone else's compliance responsibility.
The Omnisend Trap
Omnisend appears in every alternatives list. It claims to save 35% vs. Klaviyo. This is true—if you switch both pricing models.
But Omnisend is still SaaS. Your data lives in US cloud. Export takes weeks. A design change to their UI breaks your workflows. A price increase forces a reckoning.
Listmonk: The Real Alternative
Listmonk is free, open-source email software. You run it yourself—on Opsily's managed infrastructure.
No vendor lock-in. No contact limits. No per-email fees. No surprise bills.
One flat monthly fee. Unlimited contacts. Unlimited sending. Your data on your terms.
Numbers That Matter
Listmonk has 24,000 GitHub stars. Not because it's a shiny new SaaS. Because it's real infrastructure that people trust with production email.
2,267 commits show active development. Version 7.0 is in beta. This isn't abandonware.
2,700 forks mean developers are building on top of it. Customizing it. Making it do things Klaviyo's product team never dreamed of.
That's what open source means: you're not locked to a roadmap. You own the tool.
