Sender Domains are going to be mandatory

Written by Jonas Lodewegen on September 13, 2017

Using the Sender Domain functionality of Copernica ensures that the DKIM, SPF and DMARC techniques are rolled out correctly. Moreover, your sending reputation can really benefit from the fact that the envelope, click tracking and from domain are 'aligned'.

Because of the positive impact that the use of Sender Domains has on the deliverability of our customers, we will make it mandatory from the 1th of November 2017. This means that mails with a from-domain that is not a validated Sender Domain, will be blocked automatically.

Thus, please make sure that all your domains are configured correctly. More information can be found in the documentation.
