About Cllavio
One founder, one mission — email that actually lands.
I'm building Cllavio as a focused alternative to bloated marketing suites. Campaigns and API in one place, with honest pricing and inbox-first deliverability — no games, no dark patterns.
Last 30 days: 10,000,000+ emails sent with bounce and complaint protections wired in. If something looks risky, Cllavio tells you — instead of silently tanking your reputation.

Founder & CEO, Cllavio
I write the backend, ship the front-end, manage the infra, and talk to users. If something breaks, there's no anonymous “team” — it's on me.
Based in Europe • Building Cllavio full-time • Deep in email, infra & deliverability.
Why I started Cllavio
I built Cllavio after years of working with “big name” email tools for real businesses. The pattern was always the same:
- Pricing jumps the moment you grow, or you're forced into bundles you don't need.
- UIs full of features nobody uses, but somehow basic things feel slow and fragile.
- Deliverability treated like a marketing slogan, not something you can actually understand and control.
Cllavio is my answer: a focused email platform where you get a clean UI for campaigns, a straightforward Email API, and guardrails around reputation instead of hidden penalties.
What Cllavio focuses on
- • Fast dashboards for campaigns and API traffic
- • Honest limits and pricing, no hidden “penalties”
- • Bounce & complaint monitoring that actually acts
- • Clear docs so you can integrate without ceremony
- • Founder who answers when something is off
How I think about product & users
Cllavio is not trying to be “the everything app”. It's trying to be the email platform you trust enough to plug into your revenue.
01 · Clarity
No bullshit metrics
You see what matters: sends, opens, clicks, bounces, complaints. If a campaign is risky, I want you to know early.
02 · Ownership
Your domain, your reputation
Cllavio is built to protect your identity: proper DNS, separate traffic where it makes sense, and protections when things go wrong.
03 · Pragmatism
Built from real work
Every feature comes from real problems I met in production: Shopify stores, SaaS apps, and teams that actually rely on email.
What I actually do all day
I'm a backend engineer by background, but Cllavio forces me to wear all the hats:
- Designing and maintaining the email infrastructure
- Shipping features in the product dashboard and API
- Debugging deliverability edge cases with users
- Writing docs, answering support, planning the roadmap
The upside for you: there's no handoff hell. If you need something or find a bug, you're talking to the person who can actually fix it.
Cllavio in a few lines
If you're technical and want the details, ask me about the architecture — I'm happy to walk through queues, retries, and how I separate campaign vs. API senders.
Want to work directly with the founder, not a ticket system?
If you care about deliverability, clear pricing, and having a technical founder you can actually reach, Cllavio might be a good fit. Start on the free plan, plug it into your stack, and see how it behaves under your real workloads.
No sales team. No pressure. Just honest answers about whether Cllavio makes sense for your use case.
