Custom DNS Records for Rezi Email Sender Authentication

In a new effort to further protect their users’ inboxes, both Gmail and Yahoo! have introduced a new set of requirements that email senders must meet in order for mail to continue to be delivered as expected to their subscribers. If an email sender does not meet the requirements by April 2024, a small percentage of the mail will be rejected and that percentage will gradually increase over time.

A more detailed overview of the new requirements can be found on our Email Partner's website here:

It is important to note that though these new requirements are now being made compulsory for Google and Yahoo!, they have been best practice across email providers for some time and we include it on our minimum specification here:

IMPORTANT: We have identified that these new requirements will require further action on your part to ensure that you comply. Failure to act may result in emails that you send from Rezi failing to reach your clients that use Google or Yahoo email services after April 2024.
To properly authenticate emails sent from Rezi on your behalf, we require you to add custom DNS records to your domain.
