01 / The story

A geek since the Macintosh 128K

My name is Vincent, I grew up in front of a Macintosh 128K — yes, that's as old as it sounds. My first real PC was an HP tower my parents gave me. I never really unplugged since.

My first coding project was a calculator in C. A complete disaster. But I was hooked. Today I tinker with a home lab — an HP Proliant running too many things, Raspberry Pis blinking in every corner, and a constant urge to push every machine I own to its limits. That's how I unwind.

I love the passion behind old personal websites, forums where you made friends without asking who was collecting what, the innocence and constant tinkering. That era shaped me. It also taught me that a useful Internet isn't built with registrars and endless cookie banners, but with tinkerers who share.

I prefer the "freer" web of the early 2000s, with its innocence and the passion that came with it. Today, too many governments want to treat us like children under the pretext of protecting us. Vincent
02 / The project

From 3 hacked-together pages to a multi-domain service

Mail123 started tiny. Three pages, a few lines of code, a single machine. It was mostly an excuse to learn. Today it's used across several countries, with infrastructure that runs on its own. Here's how we got there.

May 2025 · v0.1

The initial hack

First version: 3 pages, a few hundred lines of code, minimalist design with a single domain. More of a prototype than a service, but it was already receiving emails.

↑ The v1 in all its simplicity — bright blue, bullet lists, and the "Recevoir les mails" button.

September 2025 · v1.0

Full graphic overhaul

Shift in direction: new dark/light design, live email reception, multi-language support, first additional domains. The service starts looking like something usable daily.

Internationalization and advanced features

Geo-localized domains (.fr, .click, .pt, .com.br), automatic OTP detection, public REST API, embeddable widget, public stats page. The service became what I would have wanted to find myself.

What's next is up to you

Webhooks, more geo-localized domains, WordPress and browser integrations, and everything you report via the contact page. The project lives thanks to its users.

03 / What I believe in

For a web that doesn't fear its users

Mail123 isn't neutral. It's a tool built with specific values, and that's what makes it different from the dozen of anonymous services doing the same thing.

A freer web

The 2000s web had its flaws, but it let everyone tinker their own corner. Today users are infantilized under the pretext of protecting them. Mail123 asks nothing: no card, no age, no reason for use.

Privacy by design

No trackers, no third-party cookies, no data resale. Mailboxes auto-delete. If I store nothing, I can't leak anything, nor sell anything. It's that simple.

Love for the craft

Mail123 runs self-hosted, depends on no SaaS. No magic framework, no black box — code I fully understand is code I can fix.

EU sovereignty

Servers in France (Roubaix). No AWS, no GCP, no Cloudflare in front of emails. Data stays in the European Union and crosses no exotic borders.

04 / By the numbers

The project in numbers

Mail123 is a small independent service, but it holds its own. A few up-to-date numbers — weekly activity, active mailboxes, and what makes the service a bit different.

05 / What I'm proud of

Three things that make me happy

When you tinker with a project for months, a few details are worth all the effort. For mail123, those are:

1. The simplicity. A visitor arrives, clicks, receives. No onboarding, no tutorial, no form. If you need instructions to use a disposable email, it's poorly designed.

2. The hidden features. Under the hood it's less minimalist. Automatic OTP code detection in received emails, multi-domain geo-localized management, public REST API, embeddable widget… All those things you only notice when you need them.

3. Internationalization. Mail123 speaks 5 languages and uses geo-localized domains. A Brazilian uses mail123.com.br, a Portuguese uses mail123.pt, a French user mail123.fr. Small detail, but that's what sets a quality service apart from an American copy-paste.

A question, an idea, a bug?

The service lives off its users. If you find a bug, have a suggestion, or just want to chat about the project — the contact page is there for that. I read everything, I reply to most.
