What Are Spam Traps?
Spam traps are inactive or fake email addresses used to catch bad email practices. Sending to them can hurt your sender reputation, reduce deliverability, and even get you blacklisted. -
Types of Spam Traps:
- Pristine Traps: Created solely to catch spammers; often result from scraping or buying lists.
- Recycled Traps: Old, inactive emails repurposed into traps.
- Typo Traps: Mistyped email addresses (e.g., "gmial.com") used to catch errors.
-
How to Prevent Spam Traps:
- Use double opt-in to verify subscribers.
- Clean your email list regularly by removing hard bounces and unengaged users.
- Use email validation tools like Bouncebuster to catch invalid or risky emails.
- Avoid buying or scraping email lists.

Why It Matters:
Hitting spam traps can cause up to 70% of your emails to be flagged as spam, damaging your campaigns and sender reputation.
| Key Action | Impact | How to Implement |
|---|---|---|
| Double Opt-In | Blocks spam traps during signups | Add confirmation step in sign-up flow |
| Regular List Cleaning | Removes invalid/risky addresses | Use monthly or quarterly checks |
| Engagement Monitoring | Flags inactive/high-risk subscribers | Track open/click rates weekly |
Spam trap prevention is ongoing work, but tools like Bouncebuster and regular list hygiene can keep your email campaigns safe and effective.
Types of Spam Traps and Their Impact
Pristine Spam Traps
Pristine spam traps are email addresses created solely to catch spammers. These addresses have never been used for legitimate communication and are often placed on public websites, forums, or directories where automated tools might scrape them. If you send emails to one of these addresses, it’s a clear sign that your list was built using purchased data or scraping methods.
The consequences? Hitting a pristine spam trap can seriously damage your sender score, lead to blacklisting, and hurt your reputation for the long haul.
Recycled and Typo Spam Traps
Recycled spam traps come from old email addresses that were once valid but have been abandoned. After a period of inactivity, ISPs repurpose these addresses as traps. Initially, emails to these addresses bounce, but over time, they turn into active traps. Typo traps, on the other hand, are addresses with common misspellings (like ‘gmial.com’) meant to catch errors or unvalidated lists.
If these traps show up in your database, it’s often a sign of:
- Poor list hygiene
- Weak email validation processes
- Irregular engagement checks
- Lack of proper email verification tools
To avoid these traps, use real-time email verification at every collection point [1][3]. Taking this step helps keep your email list clean and protects your sender reputation.
Knowing the types of spam traps is just the beginning. The next step is figuring out how to prevent them, which we’ll cover soon.
How to Prevent Spam Traps
Collect Emails the Right Way
Using double opt-in is a smart way to ensure only genuine and interested users join your email list. It helps keep spam traps – like pristine, recycled, or typo traps – out of your database.
Avoid buying email lists or scraping email addresses from websites. These practices not only violate the terms of most Email Service Providers but also make spam traps almost unavoidable.
"Purchasing email lists is a fast track to spam traps and violates most ESP terms of service." [1]
Keep Your Email Lists Clean
Regularly maintaining your email list is key to reducing spam trap risks. Here are some steps to include in your cleaning routine:
- Remove hard bounces as soon as they occur.
- Watch for engagement trends, like drops in open or click rates.
- Validate email addresses every three months.
- Remove subscribers who haven’t engaged for 6 to 12 months.
Use Email Validation Tools
Email validation tools can help you identify and remove invalid email addresses, improving your deliverability and reducing the risk of spam traps. Tools like Bouncebuster offer both real-time and bulk validation, making it easier to catch problematic addresses before they cause issues.
For the best results, pair validation tools with engagement tracking. Monitoring open and click rates can help you quickly identify and address any suspicious or inactive addresses. This proactive approach keeps your list in good shape and protects you from spam traps.
Tips for Keeping Email Lists Healthy
Track Subscriber Engagement
Monitor metrics like open rates, click rates, and bounce rates to detect potential spam traps early. Automate this process and segment your audience based on their activity levels. This helps pinpoint inactive subscribers and addresses that might pose a problem.
Once you’ve identified inactive subscribers, decide whether to re-engage them or remove them from your list.
Run Campaigns to Re-Engage Subscribers
Re-engagement campaigns are a great way to bring back inactive subscribers and identify potential spam traps. Send personalized campaigns at intervals like 3, 6, and 9 months of inactivity. Include clear calls to action and offer incentives to encourage interaction. If subscribers remain unresponsive after 12 months, it’s time to remove them.
"A smaller, engaged list is far more valuable than a large, unresponsive one riddled with potential spam traps." [1]
These campaigns not only help revive dormant contacts but also ensure your email list stays clean and responsive.
Avoid Risky Email Practices
Beyond tracking engagement and re-engaging subscribers, steer clear of practices that could harm your list. Use real-time email verification tools like Bouncebuster to catch typos and invalid addresses before they enter your database. Implement SPF, DKIM, and DMARC protocols to safeguard your sender reputation and steer clear of spam traps [2][4].
