Think Before You Delete: Why You Should Never Erase Your Spam Emails

Published September 18th, 2025 by Bayonseo

The delete button is frequently our closest friend in the daily struggle to rid our inboxes of junk. That never-ending barrage of spam—phishing scams, questionable offers, and blatant frauds—seems like digital trash that begs to be thrown away. However, what if we warned you that it could be a mistake to remove these messages? Cybersecurity experts say that your spam folder is a vital early-warning system and a vital line of protection, not just a digital garbage basket.


An unlikely cybersecurity tool is your spam folder.

There are strong arguments for allowing undesirable emails to remain, at least temporarily, despite the temptation to delete them right away:

  • Evidence for Investigations: If you are the subject of cybercrime, spam emails—particularly those connected to phishing or scams—may be used as proof. These emails can be used by law enforcement and IT security teams to track down attackers, comprehend their tactics, and even stop similar assaults in the future.
  • Training Your Email Filters: You aid the AI algorithms of your email provider by allowing spam emails to remain in your folder. To enhance their capacity to identify and weed out potential dangers, these systems examine flagged spam. By immediately eliminating spam, you deprive these systems of information that could improve both your and everyone else's security.
  • Finding Trends and Vulnerabilities: An abrupt increase in spam may be a sign that your email account was compromised. By keeping these communications, you can see patterns, like a rise in scam themes or impersonation attempts, and take preventative action, like changing passwords or turning on multi-factor authentication (MFA).
  • Preventing Inadvertent Clicks: Although it may seem paradoxical, keeping spam in a specific folder lowers the possibility that users would unintentionally interact with harmful content. Hastily deleting emails might result in accidental clicks, particularly on mobile devices.


Top Techniques for Handling Spam

This does not imply that you should keep spam on hand forever. To strike a balance between safety and sanity, adhere to these rules:

  • Review Before Deleting: Rather than just clearing out your spam folder, do it from time to time.
  • Report Phishing Attempts: Make use of the "report phishing" function offered by your email provider. This fortifies filters and safeguards others.
  • Never Engage: Even if you want to "unsubscribe," don't open links or attachments in spam emails because doing so verifies that your email is still active.
  • Establish a Retention Policy: Prior to wholesale deletion, allow spam emails to accrue for 30 to 60 days.
