Stop threats before
they reach the inbox.

Blink Mail Shield sits in front of your existing mailboxes — Microsoft 365, Exchange, cPanel, or Plesk — filtering every inbound and outbound message for spam, phishing, and spoofing, with nothing to migrate and nothing for your team to install.

Mailboxes to migrate

Blink Mail Shield is built and supported by Blink Connected, your ICT & VoIP partner — one team, one relationship, for your whole communications stack.

How it works

Three steps, no mailbox migration, live the same day.

1

Point your DNS

Repoint your domain's MX record at Blink Mail Shield — your mailbox stays exactly where it is.

2

We filter everything

Every inbound and outbound message is checked for spam, phishing, and spoofing in real time.

3

Clean mail arrives

Only verified, filtered mail reaches your existing Microsoft 365, Exchange, cPanel, or Plesk mailbox.

What Blink Mail Shield does

A full protection layer in front of the mailboxes you already run.

Inbound protection

Every incoming message is filtered for spam and phishing before it ever reaches your mail server.

Outbound authentication

Send through us with a single set of credentials, fully SPF/DKIM signed, from any number of domains.

Anti-spoofing

Only verified senders can send as your domain — impersonation attempts are rejected automatically.

Full message visibility

A real-time log of every message processed — sender, recipient, verdict, and full content on demand.

Zero migration

Works in front of Microsoft 365, Exchange, cPanel, or Plesk — just repoint DNS, mailboxes don't move.

Works everywhere

One gateway, unlimited domains, unlimited senders — built to scale with your organization.

Developer API

Every domain, message log, quarantine, and filter rule available over a plain HTTP API — automate against your own account with a self-service key.

Complete filtration, both directions

Every capability runs on inbound mail arriving at your domain, and on outbound mail sent through us.

Inbound

Mail arriving at your domain

  • Real-time spam & phishing scoring on every message
  • AI-powered analysis for business email compromise and impersonation
  • Antivirus scanning of every attachment
  • SPF, DKIM, and DMARC verification on arrival
  • Custom filter rules — allow, block, quarantine, or tag by sender or domain
  • Quarantine with self-service release, plus one-click approve sender/domain

Outbound

Mail your team sends through us

  • Authenticated SMTP relay — one credential, unlimited sending domains
  • SPF & DKIM signing applied automatically on every outbound message
  • AI-powered check against compromised-account fraud and BEC attempts
  • Same allow/block/quarantine/tag rules, applied to what you send
  • Full visibility into every server that's authenticated to send, with self-service IP blocking
  • Multiple ports (25, 465, 587, 2525) — alternates if your network blocks one

Simple, predictable pricing

One flat monthly price per account. No per-seat fees, no per-domain fees, no annual lock-in.
