This is most regrettable.
Flexmail is an email platform. This means that our customers upload their own email addresses, which they are also responsible for. We do not keep any address details, and we do not submit or sell them to our customers either.
Together with you we want to find the sender, to solve this problem in cooperation with you. Send us a copy of the unsolicited mail or information about the sender via firstname.lastname@example.org
. We will contact the sender and take the necessary steps.
