For serious senders done renting their infrastructure
One command. Your server. A complete, self-hosted mail system — DKIM, SPF, DMARC, automatic TLS and deliverability tooling — live in minutes. No per-email fees. No surprise bans. No begging support to lift a throttle.

Read this if you send more than a few thousand emails a month
Let's be honest about what's really happening to your email.
You built your list. You write the emails. You do the work. But the moment you hit send, you're standing in someone else's house — and they can change the locks whenever they feel like it.
Every month the bill creeps up as your list grows. You pay per contact, per email, per "credit" — punished for the exact thing you're trying to do: reach more people. And the more you send, the more you're watched.
You are not a customer to these companies. You are a tenant. And a tenant can be evicted.
There is another way
They don't rent. They run their own mail server. They own the sending infrastructure end to end: their IPs, their reputation, their rules. Flat, predictable cost. No per-email tax. No one to ask permission.
There was only ever one catch: setting up a real mail server — Postfix, DKIM keys, SPF, DMARC, TLS, reverse DNS, a delivery engine, monitoring — used to take a skilled sysadmin days, and one wrong setting meant everything landed in spam.
So we removed the catch.
Introducing
You bring a fresh Debian server. Our licensed installer does the rest — a complete, hardened, self-hosted mail system with a management menu for health checks, DNS records and updates. You run it. You own it. It's live in minutes, not days.
Dead simple
Pick a plan below. We email your license key and the one-line installer instantly.
On a fresh Debian 12/13 box, run sudo ./install.sh and enter your key. It provisions everything.
Add the DNS records it prints, and your own DKIM-signed mail server is delivering. That's it.
Don't have a server yet?
Half the battle of landing in the inbox is the IP you send from. We recommend Contabo — clean IP ranges, port 25 opened on request, and genuinely powerful servers for a few euros a month. It's the sweet spot for a self-hosted mail server.
A small VPS is plenty to start sending.

Everything, done for you
Not a wrapper. Not a relay you're still renting. A complete, self-hosted mail platform on your machine.
A full sending platform with database and workers — installed, configured and running on your VPS.
DKIM signing, SPF & DMARC guidance and automatic HTTPS/TLS — the things that decide inbox vs. spam.
A one-key system check confirms containers, database, TLS and mail are all green at a glance.
Generates, verifies and exports the exact SPF/DKIM/DMARC/PTR records you need to publish.
A menu that checks for updates and upgrades your server — backup, pull, migrate, restart — safely.
Your server, your IP, your data. Move it, keep it, run it forever. No account to ban, nothing held hostage.
The complete picture
A mail server delivers email — but to run lists, segments, campaigns and autoresponders like a real marketing platform, you pair it with an app. The marketer's choice is MailWizz. Connect it to your BuildYourMailer server and you own the whole stack, top to bottom.
Your own mail server — DKIM-signed delivery, your IP, your reputation. The part that gets email into the inbox and keeps it there.
Lists, subscribers, segmentation, drag-and-drop campaigns and autoresponders — the front-end your team actually works in, sending through your server.
What changes for you
Do the math
Illustrative monthly cost as a list grows — typical per-contact email platforms vs. running your own server on a VPS.
Figures are illustrative and vary by provider and volume — the pattern doesn't: rented pricing scales with your list; a server you own doesn't.
Let's be straight
In their words
"Add a real customer quote here — the outcome they got, in their words. Specific numbers convert best."
"A second quote focused on deliverability or cost savings. Keep it concrete and believable."
"A third quote about how easy the install was, or peace of mind from owning it."
Replace with real testimonials as you collect them.
Unlike a rented platform, nobody can switch you off. If you ever let your license lapse, your mail server keeps running and keeps delivering — you simply stop getting the installer, updates and support. Your data is never held hostage, and there's nothing to "cancel." You own it from day one.
Simple, one-time-per-term pricing
Pay once per term — not per email, not per contact. Prices are set on checkout; pick the fit below.

Before you ask
Your list. Your rules. Your server.
P.S. — Every month you wait, the rented bill goes up and the risk stays the same: a review, a flag, a ban you can't appeal. Owning your own mail server ends that for good — one command, one server, yours. Pick your plan and take back control.
