All email databases can contain risky email addresses like spamtraps or worse honeypots, even if you have collected your addresses with all the rigor required to have usable files. These emails could have been captured by filling in forms made by hostile competitors or simply from old valid addresses, but now used by companies that fight against spam.

To improve the performance of your shipments, CaptainVerify provides its file detection and cleaning technology, allowing you to target only verified addresses.

Spamtraps: the explanations

Inactive spamtraps

These email addresses were real, clean and active addresses. They were then closed by ISPs or webmails after a long period of inactivity. These addresses must have sent you an error message for a while which you have classified as softbounce (mailbox full or temporary error). Unfortunately some of these addresses can be reactivated to serve as spamtrap. This is the trap, if you try to reactivate your file via a newsletter, you risk being classified as spammer and your IP and domain names blocked by ISPs for spam. Spamtraps are fairly easy to isolate compared to honeyspots. After cleaning your database, simply remove the addresses at risk.

Active spamtraps also called Honeypots

An active Honeypot or spamtrap is a trap email address as indicated by its English name: Le Pot de Miel. These email addresses were designed to trap spammers. They were propagated on the web to identify hackers who suck up email databases. By using one of these emails, you will immediately be considered a spammer. Your emails will no longer leave, you will be blocked by ISPs. Whether it is your IP, domain names, and it will be very complicated to prove your good faith. There are currently national and international organizations that fight against spam, the famous spam in association with ISPs. They are nicknamed the "Black Lists", and they would be more than 250.

These trapped emails are sneaky and dangerous and can be the source of your IP blocking. The problem with Honeypots is how to identify them and no one is safe even if you have never spammed an address. They can slip during a commercial operation such as a contest or a co-registration operation.

Solutions exist. You should regularly clean up your email files and do not hesitate to delete questionable addresses from your databases. We recommend cross cleaning and algorithmic cleaning.

How to do ? What are the procedures?

Cross cleaning

The principle of this method is quite simple. As its name suggests, we will cross the data of the emails collected with those of a database of trap addresses. This method remains random. She asked to have the sources of a trap database. These sources are often random and not very reliable. In addition, you must be sure to have a database containing regularly updated trap addresses. We find this method unreliable even if it can serve as a support.

Algorithmic cleaning

This method is innovative, it goes further than cleaning by crossing. To begin with, the files will be analyzed and cross-checked with numerous files containing email Black Lists. Then, a search engine with artificial intelligence will scan your email addresses to detect possible risks.

Certain elements of an email address can generate a risk or a spamtrap alert. An email address is divided into two parts: the recipient and the domain name. The process will scan its different parts to check and generate alerts on different points:

  • Incorrect entry or spelling of a domain name
  • Anti-spam email addresses
  • Names of exotic senders:
  • Spam, cybersquatting parking domains...
  • Suspicious keywords (spam@, bulkmail@, admin@, contact@, info@, etc.)
  • Invalid DNS, wrong or incorrectly configured Mx
  • Non-existent domain names: Mole Network
  • Blakhole, unknown domain name
  • Clickbots, email lists known to be bots
  • Etc...

In the face of the danger posed by spamtraps, don't hesitate any longer! Go on the attack with regular cleaning of your email databases.

What are the dangers of spamtraps?

The risks linked to spamtraps are real. In addition to sending emails that cost you money to unnecessary addresses, you will also damage your deliverability. As with SEO, the IPs and domain names that send emails will be classified by the ISPs with a score that will determine your deliverability. This score will allow you to either deliver your emails to the inbox, to spam, or, if you are considered as spammers, do not send them at all.

Indeed, by using these so-called risky e-mail addresses, you expose yourself to a blocking of your campaigns, which can be temporary or even permanent. Google goes further by assigning an internal rating to domain names for its search algorithm. It crosses several data including the reputation of the domain name as emailers. Spam alerts could have a direct impact on your SEO.
