Continuous inbox protection · engineered in Germany

Spam is moved automatically
to the spam folder.

SpamProtec plugs straight into the mailbox you already use — over IMAP or Microsoft 365 / Exchange, with no MX change, no new address and nothing to install. New messages are checked continuously and detected spam is moved out of the way automatically.

Usually set up in a few minutes — one-time-code sign-in and automatic detection for common providers. Try free for one month (30 days) — first annual charge no earlier than day 31, cancel anytime before then. German-engineered, with support from real people — not a US call centre.

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. Basic filters often miss context, sender relationships and new variants.

Checked continuouslyIDLE events and regular checks keep watch over the mailbox.

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.

542
spam messages blocked — this week
1504
blocked — this month
7067
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.

39protected mailboxes
(= employees)
~71 hrssorting time saved per year
~981 €savings per year — at least

Estimated at about 8 seconds per automatically intercepted spam message and the statutory minimum wage of €13.90/hr (as of 2026). With higher actual personnel costs, the calculated value may increase accordingly; any potential security benefit is not included in this time-based estimate.

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 15.7 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, convincing sender impersonation and lookalike domains can evade purely rule-based filters. SpamProtec evaluates sender-domain authentication signals (SPF/DKIM/DMARC) together with the content and can therefore detect attacks that appear legitimate at first glance.

Considers spoofing and brand-impersonation signals — not just well-worn spam words.

How it works

Set up 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

For common providers, the wizard detects the server settings automatically. Microsoft 365 connects through Microsoft sign-in; other providers may require an app password or server details.

3

Protected — automatically

New messages are checked continuously. Messages identified as spam move to the spam folder, reducing manual sorting.

What SpamProtec can do

Protection that thinks — and grows with you.

Continuous protection

An IDLE connection reports new messages as events, while regular checks provide a fallback. Classification usually happens shortly after arrival, but provider conditions and load can cause longer delays.

IDLE connection rspamd + AI Event-driven + regular checks

Learns from your corrections

Move a message to the spam folder or back to the inbox and SpamProtec will take that correction into account in future checks. Security checks and higher-priority rules remain in effect.

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

Data-minimised checking — explained clearly.

Spam detection needs message content. SpamProtec technically reduces that content before external AI checks and clearly discloses providers, data flow and residual risks.

Mail arrives Recognised identifiers redacted locally Independent pattern check Verdict: spam or clean

Local redaction first

Fixed rules and a locally operated model redact recognised personal identifiers before any external AI check. Only the resulting reduced text is transmitted for classification.

Second safety check

Immediately before transfer, an independent leak gate checks again for defined data patterns. If it detects residual data, external transmission is blocked and processing continues locally.

Honest limitations

Automated redaction recognises defined patterns and learned entities, but cannot guarantee detection of every free-text reference. That is why recipients, safeguards and residual risks are clearly described in our privacy policy.

Made in Germany

Hosting in Germany, documented privacy safeguards and a data processing agreement (DPA) for business customers. Privacy is built into the architecture and documented processes.

Before external AI checks, recognised personal identifiers are redacted locally and transfer is protected by an additional pattern check; complete anonymisation of free text cannot be guaranteed technically. This may involve a transfer to third countries. Providers, safeguards and residual risks are explained in our privacy policy.

Frequently asked

What to know before you start.

Do I have to change my email address or MX record?
No. SpamProtec works directly in your existing mailbox via IMAP. No MX change, no new address, no software to install.
How fast is spam detected?
SpamProtec checks mailboxes continuously and on an event-driven basis. New messages are usually processed shortly after arrival; provider conditions and load can cause longer delays. Detected spam is moved to the spam folder automatically.
Does an external AI provider see my emails?
Before an external AI check, fixed rules and a local model redact recognised personal identifiers. An independent pattern check blocks transmission when it detects residual data. Automated redaction cannot identify every free-text reference without exception; recipients and residual risks are explained in our privacy policy.
How quickly am I up and running?
Usually within a few minutes. Sign in with a one-time email code without a password, connect your mailbox with automatic detection of the server settings, done.

Take your inbox back.

Connected in about two minutes, protected from the very first new message. Try SpamProtec on your own mailbox.
