What's changed?
Google, which runs Gmail among other email services, has started more often requiring senders to add "authentication" to the DNS entries for their domains, per: <https://support.google.com/mail/answer/81126?hl=en>https://support.google.com/mail/answer/81126?hl=en
Why can't Cloudiance add "authentication" for me?
We don't host your domain name service (DNS), so we can't make the required changes for you, however, we can direct you what to change.
What should I do first?
Start with adding an SPF record, see if that helps:
v=spf1 include:_spf.zmailcloud.com ~all
How long will it take for these changes to take effect?
It may take a day or more for Google/Gmail to update their system with the changes you've made. If necessary, or as you’d prefer, you can then move on to add the additional authentication provided by DKIM, and DMARC.
Where do you have more information about domain email authentication?
Here are links to our relevant knowledgebase articles, for your reference:
Is there anything else I can do to improve my ability to send emails to Google/Gmail?
Yes. Google publishes information on how to register and use its Google Postmaster Tools, to help domain name administrators monitor how Google rates the spamminess of their domain name(s), at least according to Google.
What does the error look like in bounced messages from Google/Gmail?
Without adding authentication to your domain’s DNS, you may receive a bounced message from Google that looks something like this:
host gmail-smtp-in.l.google.com[173.194.207.27] said:
550-5.7.26 This message does not have authentication information or fails
to 550-5.7.26 pass authentication checks. To best protect our users from
spam, the 550-5.7.26 message has been blocked. Please visit 550-5.7.26
https://support.google.com/mail/answer/81126#authentication for more 550

gsmtp (in reply to end of DATA command)
Will you ever be able to make DNS changes like these for me?
In the near future, in the second quarter of 2022, we plan to offer DNS hosting, to manage the complexity of these configurations for you. Please contact us if you're interested in beta-testing our DNS management system, which will be available through our integrated Billing & Support portal at https://admin.cloudiance.com .
I don't think it's an authentication issue. I just want Gmail recipients to receive my message in their inbox, instead of being labelled as spam.
In this case, there are several options, including for instance asking your Gmail recipients to add your email address to their Gmail contact list. Instructions you can pass on to them are here in our knowledgebase for your convenience.
