Secure Email Delivery Starts with Authentication – eco and DDV Publish Joint White Paper

Email continues to be one of the most important digital communication and marketing channels. At the same time, it is also a target for phishing, spoofing and identity abuse. Without properly implemented email authentication, companies risk not only delivery problems but also reputational damage and loss of trust among their recipients.

The requirements for sender domains have become significantly more stringent in recent years. Major email platforms are increasingly requiring binding technical standards in order to reliably deliver emails to the inbox. For companies, this means that email authentication is no longer an optional measure, but a fundamental prerequisite for successful digital communication.

The new joint white paper by eco and the DDV, “Email Authentication – The protective shield for your domain and door opener to your inbox”, highlights why procedures such as SPF, DKIM and DMARC play a central role today and how they are correctly implemented. In the white paper, you will learn, among other things:

  • why SPF, DKIM and DMARC are essential for trustworthy email communication
  • what risks arise from missing or faulty authentication
  • how deliverability and brand protection can be improved
  • what requirements major mailbox providers place on senders
  • what typical mistakes should be avoided during implementation

The white paper offers compact, practical guidance and supports companies in making their email communication future-proof.
