Security & Trust

Your email, protected in layers.

Blink Mail Shield exists to keep threats out of your inbox and prove your outbound mail is genuinely yours — without ever taking your mail out of your control.

Every inbound message is checked before it reaches you

Sender authentication (SPF, DKIM, DMARC), reputation and pattern checks, antivirus scanning of every attachment, and an AI-powered read on phishing and impersonation intent — all before a message ever reaches your mailbox.

Outbound mail is authenticated, not just relayed

Every message you send through us is cryptographically signed (DKIM) with your own domain's key, and scored by the same detection pipeline as inbound mail — so a compromised account sending spam gets caught too, not waved through just because it's "yours."

AI trained to catch what rule-based filters miss

Targeted business email compromise and executive-impersonation attempts are often written specifically to pass every traditional check — correct headers, no suspicious links, a look-alike domain. A dedicated AI layer reads intent, not just structure, to catch exactly that kind of attack.

Nothing suspicious just disappears

A message that gets held back is never silently deleted — it's saved, reviewable, and can be released by your own team in one click if it turns out to be a false alarm. You stay in control of your own mail.

Built to be reliable, not just strict

If a destination is temporarily unreachable, we don't just drop the message — it's retried automatically over an extended window before we give up and let you know, the same way any well-run mail system should behave.

Full visibility, always

Every message processed is logged with its outcome and the reasoning behind it, visible to your own team at any time — nothing about how your mail was handled is a black box.

How we handle your mail

Your mailbox never moves. We sit in front of whatever you already use — Microsoft 365, Exchange, cPanel, Plesk — and nothing about where your mail actually lives changes.

One customer's data never crosses into another's. Every account's mail, domains, and history are kept strictly separate — nobody on one account can see anything belonging to another.

A held-back message is always your call, not just ours. Anything flagged is reviewable by your own team, with a clear reason shown for why it was flagged — and released in one click if it shouldn't have been.

The AI layer is validated before it's trusted. New detection logic runs in a monitoring-only mode against real traffic, measured against real outcomes, before it's ever allowed to affect whether your mail is delivered.
