Improve your data quality and email deliverability
Do you regularly remove invalid email addresses from your mailing lists? Of course, all email sending tools have bounce management logic to mark undeliverable and invalid addresses and exclude them from further mailings... but what about mailing lists that you don't send to regularly? With target groups from your CRM or shop, with contacts from events or webinars that are contacting you for the first time? The proportion of invalid to good email addresses in your lists is an important factor in how your sender reputation is rated by major providers such as GMX, WEB.DE or Gmail. If your lists are clean, your newsletters and promotions have a better chance of ending up in the recipients' inboxes. Or are there spam traps, honeypots, or trash mail addresses hidden in your lists? Find out how many "dangerous" email addresses are in your mailing lists and keep your lists clean!

Cleansing email mailing lists
We check the validity of your email addresses using SMTP connection tests, syntax check routines, DNS validation, and numerous other tests and procedures. At the end, you will receive a report with recommendations for action: Which contacts should you stop sending to, which are not critical, which addresses should you re-qualify, if any? And: How can you adapt your processes so that such data checks will be superfluous in the future?
Effective list cleansing starts with input
Only add valid email addresses to your database! We integrate live email validation logic directly into your contact, order, or registration forms. In this way, input errors or invalid email addresses can be detected in real time. The system not only shows errors, but also offers suggestions for corrections. This keeps your list clean even and especially for new customers and interested parties. Our live service is easily integrated with all types of online forms, application processes, websites, and applications. List cleaning right from the start: you can't improve your address quality faster and more sustainably.
Even more about list cleaning and address validation
We will return addresses that have been identified as critical or undeliverable to you as a separate list or mark the critical addresses in the original list — just as you wish. In this way, you can find out how many harmful email addresses are in your shipping list and take appropriate action.
Spam traps are email addresses that are used by email service providers and blacklist operators to identify potential spammers. If you send an email to a spam trap, you may end up on a blacklist and your campaigns can no longer be delivered to all recipients.
Our address verification processes include the following checks: syntax check, DNS validation, MX record verification, recognition of temporary/throwaway email addresses, detection of typos in domains, verification of SMTP connection, verification of mailbox existence, and more. Publicare has also specialized in email marketing for over 25 years and now has an extensive and constantly growing blacklist that continuously collects spam traps.
We can't promise that our blacklist includes all existing spam traps. Such a promise would be dubious. However, we are certain that with our technical list cleaning service, we can extract the majority of critical candidates from your lists. This gives you an overview of the quality of your address base and significantly reduces your risk of being blacklisted.
Blacklisting problems caused by spam traps can unfortunately also affect reputable senders. An example is when a customer cancels their email address and the provider reactivates it as a spam trap after some time. Such addresses are ticking time bombs in your contact database. They should be defused in good time before they cause you difficulties. And if we don't find any problem addresses in your list at all? Then you have peace of mind and can get started with your marketing campaigns!
Under no circumstances should you simply delete the records that we report back to you as undeliverable or critical. Depending on the scenario, there are various options for tagging these addresses in your database and handling them separately. If you make use of our service, we will be happy to talk to you individually about the options.
When it comes to data protection and data security, we act in full compliance with the GDPR and BDSG. After ordering, we will send you a signed standard agreement for order data processing. This gives you legal protection. The removal of spam traps and trash mail addresses from your address list is carried out in a strictly protected environment from a technical and organizational point of view. Your data is processed exclusively in Germany. After completion of the project, we will delete the data you have provided immediately and without leaving any residue.
The data can be transmitted in any format and by any secure means: PGP encrypted via an SFTP server or via our secure cloud file exchange system. We will return the results to you in the same way.
