Why png mail in spam

The eternal struggle against spam!

There are several reasons why PNG files might be ending up in your spam folder:

  1. Unsolicited attachments: Spammers often use PNG files to send unwanted images, such as advertisements or malware, to unsuspecting recipients. This can trigger spam filters to flag the email as suspicious.
  2. Image-based phishing: Spammers may use PNG files to send fake images that appear to be from a legitimate source, such as a bank or online retailer. These images may contain malware or phishing links, which can compromise your security.
  3. Malware distribution: PNG files can be used to distribute malware, such as viruses, Trojans, or ransomware. Spam filters may detect these files and block them to prevent infection.
  4. Unusual file characteristics: PNG files can have unusual characteristics, such as unusual file sizes, headers, or metadata, that may trigger spam filters to flag them as suspicious.
  5. Lack of transparency: PNG files can be used to hide malicious code or payloads, making it difficult for spam filters to detect them.
  6. Overly aggressive spam filtering: Some email providers or spam filters may be overly aggressive in blocking PNG files, even if they are legitimate.

To reduce the likelihood of PNG files ending up in your spam folder, you can try the following:

  1. Use a reputable email provider: Choose an email provider that has robust spam filtering and reporting capabilities.
  2. Verify sender authenticity: Be cautious when opening emails from unknown senders, and verify the authenticity of the sender before opening attachments.
  3. Use antivirus software: Install and regularly update antivirus software to protect against malware and other types of threats.
  4. Use a spam filter: Consider using a third-party spam filter or plugin to help block spam emails and attachments.
  5. Report spam: If you do receive a spam email with a PNG attachment, report it to your email provider and mark it as spam to help improve their filtering algorithms.

Remember, it's always a good idea to exercise caution when opening emails and attachments from unknown senders, and to stay up-to-date with the latest security best practices to protect yourself against spam and other types of threats.
