Live check at your inbox
The problem

The inbox is the most open door in your company.

Junk mail, phishing, fake invoices and “your account has been suspended” scams land among your real messages every day. They cost you time and patience — and, with one wrong click, real money. Classic filters are rigid and never learn.

Checked in secondsEvery new message is assessed on arrival — not at the next sync.

Live tally

This is how much spam we have already intercepted.

Real numbers from live operation — across every protected mailbox. This is exactly the flood your inbox is spared.

74
spam messages blocked — this week
641
blocked — this month
3535
blocked — this year

That is roughly 0 hours our customers did not have to spend sorting out spam. Estimated at about 8 seconds per message (spotting and deleting) · grows with every blocked message.

A worked example — what that means in money

What the intercepted flood of spam actually saves in working time — and therefore in money.

38protected mailboxes
(= employees)
~33 hrssorting time saved per year
~459 €savings per year — at least

Based on about 8 seconds per spam message and the statutory minimum wage of €13,90/hr (as of 2026) — i.e. the lower bound. Since most employees cost a multiple of the minimum wage, the real saving is considerably higher. On top of that comes protection from a single costly phishing misclick, which is hard to offset in hours at all.

What you get out of it

Two benefits that count right away.

The numbers above become concrete: time regained and protection exactly where it gets expensive.

Time regained — every day

Every spam message you never see is time you don't lose to reading, spotting and deleting. SpamProtec takes these constant micro-interruptions off your plate — your inbox stays what it is for: real work, not tidying up.

Already 7.9 hours of manual sorting work saved — platform-wide, and growing every day.

Protection from phishing that looks real

Fake invoices, “your account has been suspended” scams, convincingly real senders and lookalike domains — exactly the attacks simple filters wave through and that make a single misclick genuinely expensive. SpamProtec verifies the authenticity of the sender domain (SPF/DKIM/DMARC) together with the content via AI, and flags a message even when it looks legitimate at first glance.

Detects spoofing & brand impersonation — not just well-worn spam words.

How it works

Protected in three steps.

No IT project, no migration. SpamProtec sits alongside your existing mailbox — you change nothing about your mail infrastructure.

1

Sign in without a password

You sign in with your email address and confirm with a one-time code. No new password, no account clutter.

2

Connect your mailbox

The wizard detects the server settings automatically (autodiscovery). You just enter the mailbox password — fully configured.

3

Protected — automatically

Every new message is checked within seconds of arrival. Spam moves to the spam folder, your inbox stays clean. Entirely without your involvement.

What SpamProtec can do

Protection that thinks — and grows with you.

Real-time protection

A persistent IDLE connection keeps an eye on your mailbox. New mail is checked within seconds of arrival — through a combination of rspamd signals and an AI verdict. No waiting for the next scan run.

IDLE connection rspamd + AI Seconds, not hours

Keeps learning

Drag a message into the spam folder — and SpamProtec remembers the sender and pattern for good. “Not spam after all”? Move it back to the inbox and that sender is let through from then on.

Confidence-tiered Self-correcting

In your own mailbox

No MX change, no new email address, no software. SpamProtec works via IMAP right where your mail already lives — your workflow stays exactly the same.

IMAP Autodiscovery No installation

Full visibility

A dashboard with statistics and a quarantine view shows what was intercepted. Plus a daily or weekly report by email — and anything misfiled is one click to restore.

Dashboard Quarantine Email report
Security, built in

Your email stays yours.

Great filtering has to read your mail. SpamProtec is engineered so it can do that without your content ever leaving your own systems in readable form.

Mail arrives Personal data removed locally Leak gate · fail-closed Verdict: spam or clean

Local redaction first

Personal data is removed on our own infrastructure through a combination of fixed rules and a local AI model before any external check takes place. Only the anonymised content is then sent to established AI providers for classification — plain-text data never leaves your infrastructure.

Fail-closed guarantee

An independent “leak gate” checks every handover. Should any residual personal data be detected, it blocks the transfer — when in doubt, nothing is sent rather than letting something slip through.

Local checking stage

For especially sensitive mailboxes you switch to the local checking stage — the pre-anonymisation and the leak gate apply here as everywhere, so external models only ever see anonymised content. Details are governed by our privacy policy.

Made in Germany

Hosting in Germany, GDPR-compliant and with a data processing agreement (DPA). Privacy here is not a checkbox in the footer — it is built into the architecture.

Only anonymised content is used for classification at established external AI providers; this may involve a transfer to third countries. Which providers these are and how we protect your data is set out transparently in our privacy policy.
