New series: No Spam - best practices, how to reduce spam Part 3 of 4

1. Using Gmail's built-in SPAM filters

‍

One of the best tools for fighting SPAM are Gmail's filters, which automatically classify messages as unwanted. To effectively manage messages marked as SPAM:

‍

• Use Gmail in your browser or mobile app (Android, iOS) to manually mark messages as SPAM or restore them to your inbox.
  
• Regularly review your “SPAM” folder to make sure important messages have not been moved there by mistake.
  
• Turn off email forwarding to external mail servers, which can reduce the effectiveness of Gmail filters.
  

‍

2. Create custom SPAM filters

‍
Gmail allows you to customize SPAM filters. Configuration options include:

‍

• Approved Sender Lists - allows you to avoid marking messages from trusted contacts as SPAM.
  
• SPAM quarantine - allows you to manually review suspicious messages before they are delivered.
  
• Bulk message filtering - helps automatically detect advertising and promotional content.
  

‍

SPAM filters can be configured at the organizational level, which means the settings will apply to all company employees.

‍
3. How do you keep your email address hygienic?

‍
One way to reduce SPAM is to avoid sharing your e-mail address in public places. To protect yourself from unwanted messages:

‍

• Don't give out your primary email address on online forums, social media or contest sites.
  
• Use a dedicated email address to register for online services.
  
• Use anonymous email address generators, which help avoid SPAM.
  

‍

If your organization uses Gmail, you can set up filters that automatically block messages from unknown senders.

‍
4. Check email sender authorization.

‍
One way to protect against SPAM is to use message authentication standards, such as:

‍

• DMARC (Domain-based Message Authentication, Reporting & Conformance) - allows organizations to verify email senders.
  
• SPF (Sender Policy Framework) - limits the ability to impersonate email addresses.
  
• DKIM (DomainKeys Identified Mail) - enables emails to be signed with a digital key, making them harder to forge.
  

‍

IT administrators can implement these technologies to reduce the risk of receiving SPAM and phishing.
‍

5. Use professional tools to manage email signatures

‍
One element of secure email communication is the HTML email signature, which can contain authentication information such as company data or links to official sites. Using professional email signature management solutions allows you to:

‍

• Increase the credibility of the sender.
  
• Avoid messages being marked as SPAM by unknown recipients.
  
• Improve the consistency of company communications.
