“A spamtrap is a honeypot used to collect spam. Spamtraps are usually e-mail addresses that are created not for communication, but rather to lure spam.”
This definition clearly highlights that spam traps serve as a way to catch those who send unsolicited bulk emails - allowing organizations to monitor and filter out these unwanted messages.
So basically - spam traps are email addresses that are set up specifically to catch spammers. These addresses are not used for communication and are never given out or signed up for anything.
They act as a decoy - attracting spammers and helping organizations like - ISPs, blacklist providers, and antispam groups - manage spam traffic. These traps are used to block emails from addresses that are known for sending spam.
Did you know? In 2023 - about 45.6% of all emails sent worldwide were marked as spam.
While the goal is to block spam, these traps can sometimes mistakenly block legitimate emails too. Remember that - falling into a spam trap can seriously harm your sender reputation - making it harder for your emails to reach real inboxes.

How Does Spam Traps Work?

Spam traps work by catching unwanted emails sent to fake or old email addresses. Here’s a simple breakdown of how it functions:
  • Creation: Spam traps are created by organizations like ISPs and antispam groups. These email addresses are never used for actual communication and are kept secret.
  • Email Sending: When a spammer sends an email to a spam trap address - it shows that they might be using poor practices, such as - buying email lists or sending emails to people who didn’t sign up.
  • Detection: Spam traps use filters to check the email addresses that send messages. They look for patterns that suggest spam, like sending emails to addresses that shouldn't receive them.
  • Action: If an email is sent to a spam trap - it can lead to the sender being flagged as a spammer. This can damage their reputation and make it harder for their emails to reach real inboxes.
  • Impact: When a spam trap detects spam - it can block the sender’s emails and possibly blacklist their domain or IP address. This means their legitimate emails might also get blocked or filtered out.
Data shows that – In December 2024 - spam messages accounted for more than 46.8% of email traffic. By understanding how spam traps work - you can take steps to avoid them.

Types of Spam Traps

Spam traps come in various forms - each designed to catch different kinds of spammy behavior. Data shows that - the most common type of spam is marketing or advertising emails - making up about 36% of all spam.
Understanding the different types of spam traps can help you better manage your email campaigns and avoid potential pitfalls.

1. Pristine Spam Traps

Pristine spam traps are designed specifically to catch and expose spammers. Also known as honeypots - these email addresses are created by organizations and added to various places on the web - but they are never used for real communication. They act as decoys to lure spammers into sending emails to addresses that don’t belong to real people.
How Are They Created?
Pristine spam traps are set up by placing fake email addresses in places where spammers might scrape or buy them. These addresses are often hidden or embedded on websites - and they are not shared publicly. When spammers collect email addresses - they might unknowingly include these traps in their lists.
Impact:
These traps are deadly and have the most severe consequences. If a pristine spam trap appears on your email list - it indicates that you might be using questionable methods to gather contacts. Sending emails to these traps can lead to immediate blacklisting by email providers.
This means your emails may be blocked or filtered out - harming your reputation and making it harder for your legitimate emails to reach real inboxes.
Pristine spam traps are a clear signal that a sender’s list management practices are not up to standard - leading to severe consequences for email deliverability.

2. Recycled Spam Traps

Recycled spam traps are email addresses that were once used by real people but have been abandoned. After they are no longer in use, these old email addresses are repurposed as spam traps.
These addresses can include old company roles like -info@company.com or support@company.com - and email addresses from former employees or individuals who no longer use the address.
Here are some examples of recycled spam traps:
  • sales@company.com
  • contact@company.com
  • john.doe@company.com
How Are They Created?
When email addresses or domains are no longer in use - they can be repurposed as spam traps by organizations. For example, an address like sales@company.com might be left behind after an employee leaves the company - or a college email might be abandoned after graduation. Once these addresses are inactive for a while - they are used as traps to catch senders who fail to maintain their lists.
Impact:
Sending emails to recycled spam traps is less immediately damaging than sending to pristine traps - but can still negatively affect your reputation over time. Repeatedly emailing these outdated addresses indicates poor list management and can gradually harm your sender reputation.
Recycled spam traps often look legitimate - which makes them harder to spot and clean up. They may cause your emails to bounce or be flagged by mailbox providers - signaling that your list is not properly maintained. This can lead to reduced email deliverability and increase the risk of being marked as a spammer.

3. Typo/Invalid Address Spam Traps

Typo spam traps are the least harmful of the three types of spam traps - but they can still be quite annoying. These traps often come from real people - who subscribe to your email list - but make a typing or formatting mistake in the process. Common typos include errors like using .con instead of .com or - typing gnail instead of gmail.
How Are They Created?
Typo or invalid address spam traps are created from email addresses that contain errors or are formatted incorrectly. These errors might include common misspellings or mistakes in the email address format. They can end up on email lists in several ways:
  • Data Entry Errors: Sometimes, when email addresses are manually entered, mistakes can occur, leading to invalid addresses being added to lists.
  • Scraping Mistakes: When spammers or list builders scrape websites for email addresses, they might collect addresses with typos or incorrect formats.
  • Deliberate Creation: Some organizations create these invalid addresses on purpose to catch spammers who do not carefully manage their email lists.
Here are a few examples of typo spam traps:
  • johndoe@gnail.com
  • sarah.smith@company.con
  • info@comapny.com
Impact:
While hitting a typo or invalid address spam trap is less severe than hitting a pristine trap - it still has a significant impact. If your emails are sent to these incorrect addresses - it signals that you might not be thoroughly cleaning and updating your email list.
It also suggests that you might not be using a - double opt-in process to verify subscribers - which can indicate less trustworthy list-building practices.
This can affect your email deliverability, as mailbox providers may view your list management practices as sloppy. Over time - sending to these traps can lead to reduced inbox placement rates and indicate that your list hygiene needs improvement.

The Impact of Hitting Spam Traps

Did you know? 2.5% of all spam emails are scams and fraud - with 73% of those being phishing emails. This is why – you need to avoid sending emails to spam traps at all cost.
Hitting spam traps can have several negative effects on your email campaigns and overall reputation. Let’s take a look at what can happen:
  • Damaged Reputation
When your emails land in a spam trap, it suggests that your list management practices may be lacking. Mailbox providers and spam filter organizations notice this and may view your sending practices as suspicious or untrustworthy. This can lead to a damaged sender reputation. Once your reputation is damaged, it can be challenging to repair. Recovering from a damaged reputation takes time and effort.
  • Deliverability Issues
Your email deliverability rate, which is the percentage of emails successfully delivered to inboxes, can drop if you are hitting spam traps. This means fewer of your emails will reach your intended recipients, impacting the effectiveness of your campaigns.
  • Higher Bounce Rates
Emails sent to spam traps often bounce back, indicating that the address is invalid. Frequent bounces can further harm your sender reputation and cause email providers to view your emails as suspicious.
  • Reduced Inbox Placement
Spam traps signal to email providers that your list might not be well-managed. As a result, many email providers may block your emails or send them straight to the spam or junk folder. This means fewer of your emails will reach your recipients' inboxes.
  • Potential Blacklisting
Hitting spam traps can lead to your email address or domain being blacklisted. Blacklists are used by email providers to block or filter out emails from known spammers. Being on a blacklist can make it difficult for your emails to be delivered to any inboxes.
  • Additional Monitoring
Email providers might start monitoring your email activity more closely if they detect spam traps. This increased scrutiny can lead to more emails being flagged as spam, further hurting your deliverability.
  • Compliance Issues
Repeatedly hitting spam traps can also raise compliance issues. It may suggest that you are not following best practices for email marketing, such as regularly cleaning and updating your email lists. This could lead to additional scrutiny and potential legal consequences if your practices are found to be in violation of anti-spam laws.

Example: Online Retailer Facing Deliverability Issues

Scenario:
“FashionTrends,” an online retailer, has an email list of 100,000 subscribers. They notice that only 70% of their emails are reaching inboxes, compared to a previous rate of 90%.
Problem:
After investigation, they find that 5% of their emails are hitting spam traps.
Impact:
  • Reduced Deliverability: With 5% of emails going to spam traps, their deliverability rate drops from 90% to 70%. This means 20,000 emails are not reaching the inbox.
  • Higher Bounce Rates: The spam traps cause an increase in bounce rates, from 2% to 5%, affecting their overall email performance.
  • Reputation Damage: Their sender reputation worsens, leading to even more emails being filtered into spam folders.
  • Lost Sales: The drop in inbox placement results in a 15% decrease in click-through rates, leading to an estimated $50,000 in lost sales over a month.
Response:
FashionTrends cleans their email list and improves their verification process, eventually restoring their deliverability rate to 85% and recovering lost revenue.

How to Identify Spam Traps?

Wondering how to identify spam traps? Here’s are some simple tips to follow:
  1. Look for Suspicious Addresses
Check if any email addresses on your list have typos - especially in the domain part. Common errors might include incorrect domains like gamil.com instead of gmail.com. These often indicate invalid or suspicious addresses.
  1. Spot Outdated Addresses
Identify and remove email addresses that appear outdated or are no longer in use. Old addresses are more likely to be converted into spam traps.
  1. Analyze Bounce Reports
It is important to know how to identify spam traps - and one way to do this is by paying attention to bounce reports from your email campaigns. If an email address consistently results in a hard bounce (meaning the email cannot be delivered), it could be a spam trap. However, it’s important to differentiate between a genuine hard bounce and a spam trap.
  1. Monitor Unusual Activity
Watch for sudden changes in email engagement metrics. A spike in bounced emails or a drop in open rates can indicate the presence of spam traps on your list.
  1. Use Email Verification Services
Specialized email verification tools can help identify suspicious email addresses. These tools can detect spam traps by analyzing the structure and behavior of email addresses.
  1. Check for Low Engagement
Email addresses that consistently show no engagement or interaction (like opening or clicking on emails) might be spam traps. If an address has been on your list for a long time without any activity, it could be a sign.
  1. Review Subscription Sources
Be cautious about where you collect email addresses. If you use sources that are not reliable or if addresses are obtained through questionable methods, they may include spam traps.
  1. Analyze Complaint Rates
High spam complaint rates can be a red flag. If you receive complaints from email providers or users about unsolicited emails, spam traps might be involved.
  1. Check Blocklists
If you suspect spam traps, verify if your IP address or domain is listed on blocklists. Some common ones to check include:
  • SpamCop Blocking List (SCBL)
  • Barracuda Reputation Block List (BRBL)
  • Invaluement
By following these steps and using the right tools, you can better identify and manage spam traps - keeping your email list clean and your sender reputation intact.

  • Avoid Purchasing Contact Lists
Purchasing email lists from third parties can be tempting, but it often leads to problems, including spam traps. These bought lists frequently contain outdated, incorrect, or fake email addresses that may have been set up as spam traps.
Since these addresses are not acquired through genuine means, they can hurt your email deliverability and damage your sender reputation. Instead of buying lists, focus on growing your own list through organic methods.
  • Use a Double Opt-In Process
When someone signs up for your email list, send them a confirmation email. This email should ask them to verify their subscription by clicking a link. This process guarantees that the email address is real and that the person truly wants to receive your emails. It helps prevent fake or incorrect email addresses from being added to your list.
  • Check Subscription Sources
Make sure that email addresses are collected using reliable and secure methods. Avoid using sources that might give you fake or spam trap addresses. By only using trustworthy methods to gather email addresses, you reduce the risk of adding spam traps to your list.
  • Engage with Subscribers Regularly
Stay in touch with your subscribers by sending them regular, engaging content. This keeps your list active and helps maintain interest. When subscribers are actively interacting with your emails, it’s easier to spot and remove inactive or invalid addresses.
  • Implement a Welcome Series
Send a series of welcome emails to new subscribers. This series confirms their interest in your emails and keeps them engaged with your content. It’s a way to ensure that new subscribers are genuinely interested in receiving your emails and helps you build a more reliable list.
  • Ongoing Monitoring
Regularly monitor your email performance and conduct audits to make sure that no spam traps are introduced into your list. Keeping an eye on metrics like bounce rates and engagement helps you quickly address any issues and maintain a healthy email list.
