What are Spam Traps?

A spam trap is an email address that is used to capture spam, also known as an email honeypot. These email addresses are not intended for daily correspondence; instead, they are used to catch spammers.

To avoid legitimate users and email senders from falling into this pit, spam trap email addresses are never directly accessible or published on any website.

Spam Trap is a powerful tool in the arsenal of email providers for combating spam. However, since no system is flawless, legitimate senders will fall into this pit and have their domain and IP address identified on the DNSBLs blacklist. If this occurs, there are ways to exclude yourself from email blacklists as well.

Who Makes Spam Traps and Keeps Them Running?

DNSBLs (Domain Name System-based Blackhole List), anti-spam companies, and Internet Service Providers own and manage spam traps (ISPs).

  1. DNSBL: Domain blacklisting services own 92 percent of spam traps and spread them in various secret locations around the internet to capture and retain potential spammers.

These DNSBLs are particularly active in places where spammers try to scrape email addresses, such as public forums and blogs. To build and deploy these traps around the internet, most DNSBLs have their own platform and partner network.

  1. The ISP: Every big email ISP, such as Gmail, Yahoo, or AOL, holds a list of spam trap email addresses on their servers. Hitting this type of spam trap is much worse than hitting DNSBLs, since your sending domain and IP address can be permanently blacklisted. Delisting is almost impossible, and it can have a major impact on your email deliverability.

Types of spam traps:

Pristine spam trap

Email addresses provided by ISPs and other organizations are known as pristine spam traps. This is the first time a sender has used these email addresses.

So, how did they end up on contact lists in the first place?

Since the email addresses are embedded in websites, the spam traps end up in spammers’ contact lists as they scrape websites to expand their contact lists. On purchased or leased lists, pristine spam traps can also be found.

If an ISP notices someone sending to a spotless spam trap, it’s a red flag that the sender is using dubious contact-gathering methods.

While all spam traps have a negative impact on your sending credibility, the pristine spam trap is the worst. If you include this form of spam trap in your contact list, your IP address or domain will most likely be blocked.

Recycled spam trap

Domain registrations or email addresses that were once legitimate but have been reassigned for spam trapping are examples of recycled spam traps. A couple of common examples are role addresses (sales@, info@, support@) or email addresses of employees who are no longer with the company.

Although the recycled spam trap is less harmful than the pristine spam trap, it can still hurt your sending reputation over time.

Invalid email addresses

If someone subscribes with a mistake or an intentionally false email address, for example, when someone is asked to supply an email address but does not want to be emailed. You run the risk of it being a spam trap email address through pure chance.


Email addresses with a typo in the domain name, such as @gnail instead of @gmail, are an example. The most popular spam traps are typos on the domain side of the address, after the @, but a misspelt username — the part before the @ — can also catch you off guard.

Fake addresses

Fake emails are regularly sent to website registration and shopping cart forms. You will understand how this works if you have ever had to give out your email address in return for a “free whitepaper.” Someone could send an address like, which could be a spam trap.
