It’s time to set up a DMARC policy on your sending domains

As of February 2024, senders of large-scale emails will be required to add in an extra layer of security to ensure continued delivery of campaigns.

What is DMARC and why do you need it on your sending domains?

At the end of last year, both Google and Yahoo announced that something called a DMARC policy would be necessary for senders of bulk email by February 2024. This refers to senders who are sending more than 5,000 emails at a time into either of these inboxes.

DMARC stands for Domain-based Message Authentication, Reporting and Conformance. In basic terms, it acts as an extra layer of security for your email domain, helping to protect it from certain scams and fraud – things that could ultimately become the source of an email data breach. 

If this applies to you, it is your responsibility to have the DMARC policy on your domain (and any subdomains) by February – giving you two weeks from the date of this blog or so to act before this change becomes live. Failure to do so could result in your emails failing to be delivered, and severe damage to your sending reputation. Not to worry! DMARC can be easily added through your mmunicMail account. 

How to set-up a DMARC policy for your domain:

Watch the video below for easy step-by-step guidance on setting up your DMARC. Either yourself or a member of your team will require access to your domain’s DNS records to carry out this process. 

Charlotte from mmunicMail explains how to set up your DMARC policy in the system.
  • Log into your mmunicMail account here and go to the System Monitor in the top right corner (indicated by the speedometer icon).
  • Click the ‘Sending Domains’ panel.
  • Look down the list of your sending domains for any where the DMARC column is flagged ‘Not set’ with a yellow icon, and click the domain name itself to go into that sending domain’s Overview page.
  • In the top right corner, click ‘Upgrade to DMARC’ to open the Domain Authentication checker.
  • The system will give you the details of a basic DMARC record to add to your domain’s DNS records. If you have access to your domain’s DNS records, you should go there and add this record now. Otherwise, use the ‘Share’ button to generate a link that you can send to your web team that contains the information they’ll need to add.
  • Once the DMARC record has been set up, return to the Domain Authentication checker and hit ‘Run Tests’. mmunicMail will now check to make sure it recognises the DMARC record. New DNS records can take up to 24 hours to propagate, so try again in a few minutes if the record doesn’t show.
  • Once mmunicMail has verified the record, your domain will now have a green ‘Verified’ shield under DMARC in the Sending Domains overview page.

You’re all done – DMARC is now set up on your domain and you should be able to continue sending without issue.

Other authentication requirements are coming this year that may impact your email deliverability

On a whole, both Yahoo and Google will be monitoring email senders throughout the first half of this year in an effort to raise the standard of the mail they allow into their inboxes.

They will expect proper authentication of mail and low complaint rates from all senders, regardless of send volume. However,higher-bulk senders will require DKIM, SPF and DMARC authentication. If these conditions are not met, you will see the number of rejections of your emails increasing month on month. But thankfully, platforms such as mmunicMail make it really easy to check for these authentication records and give you tailored instructions on how to add them if they’re not there.

Finally, bulk-senders (for those sending over 5,000 emails) will be expected to implement a one-click unsubscribe button in all promotional emails by June of this year – we will remind you again closer to the time!

If you are unsure of whether you might need DMARC, or are experiencing any issues with deliverability, please get in touch with a member of our team today and we will be happy to guide you through the process. Alternatively, check out this article from dmarcian for a more in-depth look into the new DMARC policy expectations.

Happy sending!
