Email Filters and Anti Phishing Solutions

What is Email Filtering?

Email filtering refers to the process of automatically sorting, organizing, and prioritizing incoming emails based on predefined criteria, such as:

  • Sender’s email address
  • Subject line keywords
  • Content keywords
  • Attachment types
  • Spam scores

Email filtering helps manage email overload, reduce spam, and increase productivity by:

  • Blocking unwanted emails (spam, junk)
  • Redirecting emails to designated folders (e.g., newsletters, social media)
  • Flagging important emails for priority attention
  • Automating email routing and forwarding
  • Applying custom rules and policies

2 Types of Email Filters

SPAM FILTERS
Every day, people and businesses get flooded with unwanted spam emails. Luckily, most email programs have built-in filters that automatically block suspicious messages, protecting you from:

  1. Harmful links
  2. Malicious content
  3. Phishing scams

These filters help keep your inbox safe and clutter-free.

FIREWALLS
A firewall blocks unwanted internet traffic from entering your network. It follows rules set by your organization to:

  1. Stop spam emails (SMTP)
  2. Block suspicious activity
  3. Keep your network secure

Email filtering can be applied at various levels, including:

  • Server-side filtering (by email providers)
  • Client-side filtering (by email clients)
  • User-defined filtering (custom rules set by users)

Email filtering helps improve email management, reduce noise, and enhance overall email experience.
