Aside from SPF, DKIM and SenderID, it is also perfectly possible to use the DMARC authentication process to optimise your delivery rates. The only prerequisite is the use of an own, dedicated IP. You will also need to allocate a subdomain to your domain. Only once you have done this can you build up an IP reputation and implement records in the DNS settings.

If you happen to already use a dedicated IP with Newsletter2Go then please contact our service team so that we can set up the desired DMARC authentication for you. If you do not currently use your own dedicated IP for sending newsletters, find out more about them here. Talk to us. We are looking forward to helping you.
