There are a few tools you can use that will help you to evaluate your sender reputation and show you whether you’re sending emails to any spam traps or to your legitimate customers.

Types of Spam Traps

1. Pristine: These spam trap email accounts have never been valid emails and couldn’t even opt into receiving an email. These are available on public websites but hidden within the site’s code.

The primary purpose of pristine traps is to identify email marketers who use poor list building practices.

2. Recycled: This spam traps were once valid email addresses but have been repurposed by their provider. Someone could have used this address to opt-in at one time, but these addresses may have been abandoned.

The best tips on how to avoid falling into a spam trap email address:

, The Complete Guide on Spam Trap and How to Avoid It

1. Choose a reputable Email Service Provider (ESP)

Email Service Providers increase your reputation greatly depending on how good their status is. 

When Email Service Provider’s clients send valuable and relevant content and have a high score on their IP addresses, their emails become trustworthy.  

Non-reputable ESPs, however, have their IP addresses typically blocked by reputable ESPs like Gmail, Yahoo! Mail, or Hotmail.

2. Never buy email lists!

Are you thinking of purchasing an email list? Legally, it represents a violation of ISP’s terms of service. Selling or transferring email addresses to others is illegal and will land you in hot water with the law. 

It also represents a violation of privacy to those people whose addresses are on the list as they didn’t accept contact with you. 

The examination from Convince and Convert demonstrates that email records that have 10% unknown user addresses tend to have 44% of their emails undelivered by ISPs!

These email lists contain info that is out of date and as such, usually includes inactive or dormant addresses or recycled spam traps. 

These lists are harvesting, and chances are they will contain real spam traps. It is a one-way trip to email marketing hell to end up in a spam trap, so avoid buying email lists!

3. Verify your email lists periodically

You need to make sure your email lists are verified and have no chance of a hard bounce, or being undeliverable.

You have to check your email lists to find which email addresses and domains no longer exist, and which addresses are suspicious. 

Having a high-quality email list helps reduce hard bounces, which means you send emails to only those accounts which exist. This is an excellent marketing practice to follow.

If you send emails to invalid addresses, you’ll end up with a hard bounce. These email addresses hard bounce your emails today, and spam traps them in the future.

You can detect invalid email addresses, and prevent ending up in spam traps as a result, by using email verification services.

4. Regularly send an email

Your subscribers will forget you if you send too few emails.  On the other hand, send too many emails, and your subscribers will get annoyed.

Therefore, it’s better to send emails on a fixed schedule that maintains frequency. As you can see in the above graph, industry average open rates change in different categories.

With regular frequency, you can spot if any of your email addresses become invalid. You can then suppress those emails from your email list before they become spam traps.

Most leading ESPs consider the following factors when dealing with spam complaints.

5. Avoid spam trigger words

Pay attention to the subject line of your email to avoid hitting spam filters. The ideal approach to avoid being ‘marked as spam’ is to avoid acting like spam. Utilizing spam trigger words can increase the probability of being caught in a spam filter.

Certain words and phrases are blacklists with spam mail. Words like ‘free,’ ‘best price,’ and ‘cash’ are usually collected from spam emails and should be avoided. 

Review every one of your email subjects to understand that offering a free prize in the subject line is a byproduct of following two or three stages the customer receives once they open the email.

Here are examples of good subject lines:
“Hi [name], [question]?”
“Did you get what you are looking for?”

6. Monitor open and click rates

Sending out an email is half of the process of your email marketing campaigns. You need to consider open and click rates to understand the full engagement picture. 

The addresses that consistently fail to show open rates, especially long term like the past six to twelve months, are prime candidates for future spam trap.

If people don’t open your emails or are not interested in your emails, why send them emails? It’s better to ask them if they’d like to continue receiving your emails than it is to be blacklisted. 

The best way to avoid that is to verify your email list with bulk email verification service. Using these services, you come to know valid email addresses and can reach your intended audience.

Separate email addresses that haven’t engaged for nearly a year and inform them they can continue being on your email list by opting in again.

If users still don’t opt-in, remove them from your email list, and eliminate your risk of being caught in a spam trap.

7. Recycled spam traps

Remember that old email address you abandoned years ago that went something like [email protected]?

Of course, we all do. Well, sometime after you chose to get rid of it, your provider turned it into a trap. “smartboy111” is currently attracting spammers to expose and block them. Smart-boy indeed!

It is also possible that you collected legitimate emails years ago that now are spam traps. That’s tricky! Years ago, you had no way of knowing their abandoned emails would be used to attract spammers.

8. Use a double opt-in

If you are building an email list of new subscribers, how will you verify that recipients want to receive emails from your brand?

Almost everyone recommends using a double opt-in method, which requires a subscriber must confirm before officially ending up on your email list.

Having subscribers utilize double opt-in demonstrates they have an authentic enthusiasm for your emails, and they are not spamming traps. 

For example, I am searching for Puma shoes, and I find a website that has an email sign-up box. When I enter my email address, I typically receive an email where I need to confirm my subscription. Only after clicking “confirm subscription” am I officially a subscriber to the Puma shoe website.

9. Authenticate your email with SPF, DKIM, and DMARC

Email authentication can be complicated, but it’s easy to remember that authenticating email verifiers you are who you say you are! 

Providers like Google and Yahoo! trust authenticated email more and are more likely to deliver mail from an authenticated email into the inbox.

Here is the graphical representation of how emails are authenticated: 

, The Complete Guide on Spam Trap and How to Avoid It

Here are some methods to validate your email and prove to the inbox providers your email is worthy of the inbox and not a spam folder:

  • Sender Policy Framework (SPF) – SPF ensures you are who you say you are by comparing the sender’s IP address with a list of IPs authorized to send by that domain.
  • Domain Keys Identified Mail (DKIM) – DKIM ensures that the email was not tampered with during transmission.
  • Domain-Based Message Authentication Reporting and Conformance (DMARC) – DMARC leverage the power of both SPF and DKIM. It requires both to pass in order to send and deliver email.

10. Avoid blacklists and monitor your IP reputation

Every email domain has a reputation associated with it, and if it slips up or sends an email to a spam trap, you may find yourself in an email blacklist. Unluckily, even cautious senders may find themselves on a blacklist.

You can reduce the risk of ending up on a blacklist by considering some of the following:

  • Use double opt-in
  • Implementing a policy to remove unengaged subscribers

Using real-time email address verification helps if someone raises the false spam alarm and your sender score suffers or if you send an email to an invalid email address.

Watch out for your delivery rates as well since it will advise whether you might be on a blacklist.

Bonus Tip

You have to clean your database regularly to keep your email list safe from spam traps. Create a list of subscribers who haven’t opened any of your emails in the last 6-12 months — design a newsletter to reengage specifically with them.

If it does not work and they don’t sign up, delete them. By doing this, you will save time and money on clients who can purchase your product or service.
