How to Stop Receiving Spam Emails in 5 Steps
Spam emails can feel like the unwanted guest that just won't leave. No matter how often you delete, block, and try to ignore them, they return. And besides being annoying, spam emails take up valuable space in your inbox and can even pose security threats.

One of the best tools for cleaning up spam emails is Inbox Zapper's Gmail cleanup tool. This AI-powered solution can help you quickly remove spam from your inbox so that you can enjoy an organized email.
Risks of Spam Emails
1. Malware Distribution: The Hidden Dangers of Spam Emails
Spam emails can harbor malware, including viruses, spyware, and ransomware. These malicious programs can sneak into your system, disrupt operations, and steal sensitive data.
2. Phishing Attacks: Spam Emails Favorite Trick
While spam is generally unsolicited bulk messaging, it often overlaps with phishing attempts. Phishing emails are crafted to deceive recipients into divulging personal information, such as login credentials or financial details, which can lead to identity theft or financial loss.
3. Resource Drain: How Spam Emails Affect Business Productivity
High spam volumes can overwhelm email servers and storage systems, leading to decreased performance and increased business costs.
4. Reputation Damage: When Sending Spam Is Not Your Fault
If a business's email system is compromised and used to send spam, it can damage the organization's reputation and lead to blacklisting by email providers.
5. Legal Consequences: Spam Emails Can Get You Sued
Sending spam can violate laws like the CAN-SPAM Act, leading to legal penalties. Even inadvertently facilitating spam distribution can have legal ramifications.
6. User Fatigue and Missed Communications: The Real Cost of Spam Emails
An inundation of spam can cause users to overlook important legitimate emails, leading to missed opportunities or critical information.
How to Identify Spam Emails
1. Look Out for Odd Sender Email Addresses
Legitimate organizations use their domain names for email addresses (e.g., @company.com). Be cautious if the email is from a public domain like @gmail.com or contains misspellings (e.g., @paypall.com).
2. Unusual Content and Style Should Raise Red Flags
Phishing emails often contain grammatical errors, unusual phrasing, or an urgent tone (e.g., "Act now" or "Your account will be suspended"). They may also differ from the organization's typical communication style.
3. Questionable Links and Attachments Can Indicate a Scam
Hover over any links to see the actual URL before clicking. Be wary if the link doesn't match the displayed text or leads to an unfamiliar site. Unexpected attachments, especially with generic names like "invoice.pdf," can also be malicious.
4. Requests for Sensitive Information Are a Sign of Fraud
Be skeptical of emails asking for personal details, passwords, or financial information. Legitimate companies rarely request such information via email.
5. Security Red Flags Are a Clear Signal of Trouble
Emails that pressure you to bypass standard security procedures or threaten negative consequences for inaction are likely fraudulent.

2. Use Email Filters to Manage Spam Emails
Email providers like Gmail and Yahoo have strong spam filters that automatically eliminate unwanted emails. Take advantage of these tools to stop receiving spam emails. If any spam makes it to your inbox, mark it as spam or junk. This helps the filter learn your preferences and eliminate similar emails in the future. Also, occasionally check your spam or junk folders to ensure non-spam emails don’t end up there.
3. Block Unwanted Email Senders
Another way to stop receiving spam emails is to block unwanted email senders or domains. Almost every email service can block email addresses or entire domains (the part of the address after the @). Check your email provider’s settings for steps to block unwanted emails.
4. Understand How Companies Use Your Email Address
When you give a website or app your email address, you may end up on their marketing email list. But different companies handle your privacy differently. Some may even share or sell your email address to third parties. Before you hand over your email to a company, check their privacy policy to see how they’ll use your contact information.
5. Unsubscribe From Email Lists You No Longer Want
Most email providers have features to help you unsubscribe from unwanted email lists. When you open one of these emails, you’ll often see a banner at the top of the message letting you know how to unsubscribe. You may also click a button to remove your email from their list. To find out what options your email provider has, search online for the name of your email provider, plus how to unsubscribe from unwanted emails.
7 Email Security Tips Against Spam Emails

1. Implement a Robust Spam Scoring System
Email servers and secure email gateways typically come with built-in spam filtering capabilities. These filters rely on scoring systems that analyze inbound messages for spam-like characteristics and assign a score based on this analysis. Most email security products use industry-standard tools to perform these tasks.
For instance, SpamAssassin is a widely used open-source program that can be customized to meet the needs of individual users. In both MDaemon and SecurityGateway, administrators can adjust the spam score threshold to make the spam filter more aggressive at blocking junk email.
2. Block Connections from Spam-Relaying Servers
Mail servers and gateways can block email from suspicious servers that are known to relay spam. DNS-Blocklist (DNS-BL) services, such as Spamhaus, maintain databases of IP addresses of email servers identified as relaying spam. When a message arrives, email servers equipped with DNS-BL lookup services automatically check the sending server’s IP address against the DNS-BL database. If there’s a match, the receiving server either rejects the message outright or adds points to the spam score of the incoming message.
3. Block Emails with Malicious URLs
Like DNS-BL services, URI-Blackhole (URI-BL) services maintain databases of malicious URLs. When an email message arrives, these services check any URLs found in the message against their database. Because spam and phishing emails often contain links to nefarious websites controlled by hackers, URI-BL services help protect users from these threats.
4. Block Email from Unauthorized Geographic Locations
Spam is a global problem, so another way to protect your business is to use geoblocking or location screening to block emails from countries with no legitimate business. Blocking email from specific regions can reduce a surprising amount of spam.
5. Block Unwanted Auto-Responder Messages
Spammers often forge the return-path of outbound spam emails with valid sender addresses to route spam out so they don’t have to deal with the bounce-backs generated by receiving mail servers when this mail is addressed to invalid email addresses. This can lead to an influx of non-delivery (NDR) and out-of-office auto-responders being sent to the forged address. This is known as backscatter and can be prevented with backscatter protection.
Backscatter protection works by inserting a unique code into the return-path address of all outbound messages. Backscatter protection will check any email that arrives with a MAIL FROM address of either “mailer-deamon@” or a NULL reverse path (no Return-Path value) to ensure the associated RCPT TO value (recipient address) contains the backscatter protection code that was generated on the mail server. If no such code exists in the RCPT TO value, the mail server knows it didn’t develop the original email that the bounce-back refers to and will refuse to accept the message.
6. Deter Abusive Behavior by Spammers
Spammers often try to send junk email to as many recipients as possible. Tarpitting lets you deliberately slow down a connection once a specified number of recipients (RCPT commands) have been received from a message's sender. This is to discourage spammers from using your server to send unsolicited bulk email.
7. Optimize Your Spam Filter
As bad actors continue changing tactics to thwart detection, spam filters must evolve to keep up with the latest threats. One way to protect against emerging spam variants is to update your spam filter regularly. Make sure you are using the newest version of your mail server or secure email gateway, and if your server or gateway uses SpamAssassin or another anti-spam service, make sure it’s configured to check for spam filter updates regularly.
