Each import is manually checked by a Quentn employee. In order for your contacts to be released, a number of conditions must be met:
- The questionnaire must have been filled out completely and truthfully.
- The URLs of the entry pages have been provided if the contacts have entered via a form.
- If the contacts came from somewhere else, the source was named.
- The unchanged original file from your previous email marketing provider is available, including the column "Email status" and bounce status (if you were with another provider).
- The contacts have already completed a double opt-in. If not, this must have been indicated in the questionnaire!
- This is not a purchased data set.

Only if your list is impeccable will your email sender reputation remain high.
What is an email sender reputation?
An email sender reputation is a score given by an Internet Service Provider (ISP) to a company that sends emails. The score represents the ranking of your IP address against others - the score is crucial for the deliverability of your email! The higher the score, the more likely the emails are to reach the recipients. If the score falls, the e-mails are sent to the recipient's spam folder or rejected from the outset.
The following factors influence the score:
- the number of mails sent by the company
- how many recipients have marked the company's mails as spam
- how often the service provider has marked the mails as spam
- if the company is on various blacklists
- how often the mails could not be delivered, e.g. because they were sent to non-existent addresses
- whether there is evidence of a double opt-in
- how many recipients open, reply to, forward or delete the email or click on links in the email
- how many recipients unsubscribe from the list
Quentn helps you to achieve a good score already during import. We recognise and eliminate addresses that are not valid or that are spam traps.
What are spam traps?
Some e-mail service providers (ESP) have set themselves the task of systematically excluding all senders who do not adhere to the rules of the game for e-mail marketing that apply in Germany. These rules include, among others: the double opt-in procedure (DOI) and the imprint obligation. The ESPs check for violations by using spamtraps, among other things.
A spamtrap is a bot (computer) that automatically enters itself into forms and listens for incoming emails. The aim of the spamtrap is to find out whether a sender continues to send e-mails even without a click confirmation (DOI).
There are various technical ways to protect against spamtraps:
- Quentn uses both form-based and IP-based algorithms to keep spamtraps away from its customers. Mass registrations (flood attacks) are also automatically detected and prevented by Quentn. Unfortunately, these technical measures are never sufficient to filter out all spamtraps.
- Purchases: A spamtrap never buys a product. If a contact comes from a payment provider (Digistore / Affilicon / Paypal / etc.), you can safely assume that it is not a spamtrap. Also, most payment providers offer a checkbox where the buyer can give their consent to the newsletter.
- Facebook: Spamtraps do not use Facebook accounts. Here, one can also be fairly sure that it is a genuine registration. The user can also give his consent on Facebook.
At what point do spamtraps become a problem?
If an ESP detects that several spam traps are hitting a sender, the sender will be checked further and, if necessary, put on the blacklist. In the worst case, even the IP addresses of the newsletter service (in our case: Quentn) are blocked.
Incidentally, ESP spam traps do not necessarily use an obvious ESP address, such as @t-online.de addresses, but often use other, inconspicuous addresses, e.g. @gmail.com, @yahoo.com, etc.).
