Your challenge


Your company maintains several thousand e-mail addresses of existing and prospective customers. You intend to use that distribution list more intensively for e-mail marketing purposes. But is the quality of your e-mail addresses adequate? The many undeliverable addresses it contains call that into doubt. So what can you do to make your e-mail marketing more effective? Is there a method to test the addresses before use? Can you reactivate undeliverable addresses?

Our solution


At LUMITOS we successfully send out over 5 million e-mails per year. This is why we are aware how important address quality is to reach B2B target groups effectively. Based on 12 criteria, we will analyze your addresses. Our test routines show up typing errors, duplicates, missing salutations and titles, false names and non-existent e-mail addresses. After dissemination, we analyze the autoresponses to detect, for example, recipients whose domain has changed due to a merger or acquisition. This is how we ensure a high delivery rate and that your message reaches those it is supposed to.

Your benefits


  • You’ll reach significantly more recipients and address them correctly
  • You’ll increase the value of your distribution list
  • High-quality addresses reduce the risk that your e-mails are classified as spam
