Spam

How it works

• Sent in bulk to huge lists.
• Filters score messages by sender reputation, content and patterns.
• Real mail can land in the junk folder and junk can land in the inbox, so the filter needs tuning.
• Phishing is spam with a target.

What can go wrong (example scenario)

A five-person retail shop's shared info@ mailbox received two hundred junk messages a day. Staff stopped reading it. A real customer complaint and a supplier's shipping notice both sat unread for a week.

How WILDCARD handles it

Email Security filters every inbound and outbound message in real time. The junk stays out, the phishing gets caught, and your real mail arrives. Outbound filtering also stops a compromised account from sending spam in your name and getting your domain blocklisted.

• A law firm's intake address gets flooded with SEO offers and buries a real referral.
• A contractor's Microsoft 365 default filter lets through “invoice attached” junk with a malicious file.
• A non-profit sends a newsletter without an unsubscribe link and gets reported as spam by recipients.

Example scenario: A small bakery's owner found she was spending twenty minutes each morning deleting junk from the orders mailbox. After filtering went in, the mailbox held only real orders, and one phishing message pretending to be the flour supplier was caught before she ever saw it.

A question owners ask

Microsoft already filters spam. Why add more?

Default filters catch obvious bulk mail and miss targeted impersonation. An added layer scans for lookalike domains, payment-change language and malicious links that slip through.
