Quick Answer

DMARC (RFC 7489) ties SPF and DKIM together by requiring alignment between the envelope sender and the visible \`From\` header. According to Google's February 2024 bulk sender requirements, a DMARC policy of at least \`p=none\` is now mandatory for any domain sending 5,000+ messages per day to Gmail users. DMARC Report

> The email authentication landscape changed permanently in 2024, says Brad Slavin, General Manager of DuoCircle. Google, Yahoo, and now Microsoft all require DMARC. What used to be a best practice is now a hard prerequisite for reaching inboxes. Organizations that delayed are now paying the price in deliverability.

DMARC ([RFC 7489](https://datatracker.ietf.org/doc/html/rfc7489)) ties SPF and DKIM together by requiring alignment between the envelope sender and the visible `From` header.

Google Calendar invites fail [DMARC checks](https://dmarcreport.com/tools/dmarc-checker/) when the recipient replies to them, and the response goes back to \*\*Google’s servers instead of the sender’s domain. _This happens because the ‘From’ address and the originating server don’t match_.

This failure also occurs due to the fact that Google uses shared [IP addresses](https://www.techtarget.com/whatis/definition/IP-address-Internet-Protocol-Address) to send **Google Calendar invites**. So, if any of these IP addresses have had [spam complaints](https://help.campaignmonitor.com/s/article/spam-complaints) registered against them, the invites sent using them won’t go through DMARC checks. You can fix the issue by adding Google’s [DKIM record](https://dmarcreport.com/blog/dkim-examples-a-comprehensive-guide-to-email-configuration/) to your DNS and enabling DKIM authentication on [Google Workspace](https://en.wikipedia.org/wiki/Google%5FWorkspace).

## How to Fix the Google Calendar Invite Issue in 2024?

As suggested above, you can fix this in simple steps.

## Step 1: Add Google’s DKIM Record to Your Domain’s DNS Zone

- Visit the [Google Workspace admin console](https://admin.google.com/).
- Select ‘Settings for Gmail.’
- Then, select ‘Authenticate Email.’
- Copy the record that will be used by Google to sign your emails for **authenticity and integration**.
- Add the copied DKIM to \_google.\_domainkey.
![Dmarc office 365 7601](https://media.mailhop.org/dmarcreport/images/2024/05/dmarc-office-365-7601-1.jpg) 

## Step 2: Enable DKIM Authentication on Google Workspace

- Visit the Google Workspace admin console.
- Select ‘Settings for Gmail.’
- Then, select ‘**Authenticate Email**.’
- Click on ‘Start Authentication.’

## Additional Best Practices

To increase the chances of [Google Calendar invites](https://support.google.com/calendar/answer/37161?hl=en&co=GENIE.Platform%3DDesktop#zippy=%2Csend-event-invitations-and-updates)’ emails passing [DMARC](https://dmarcreport.com/), you can also follow some best practices-

## 1\. Use Custom Domain For Sending

_Avoid using a generic domain like @gmail.com or @google.com. Instead, use a [custom domain](https://www.namecheap.com/guru-guides/what-is-a-custom-domain/) that aligns with your company’s name_. This better aligns the ‘From’ address in the [email headers](https://www.hostinger.in/tutorials/email-headers/) and the **sender’s domain**.

## 2\. Implement SPF and DKIM

Ensure that your domain has DKIM and [SPF records](https://dmarcreport.com/tools/spf-record-generator/) properly configured. [DKIM](https://dmarcreport.com/what-is-dkim/) (DomainKeys Identified Mail) adds a [digital signature](https://en.wikipedia.org/wiki/Digital%5Fsignature) to emails, while [SPF](https://dmarcreport.com/what-is-spf/) (Sender Policy Framework) specifies which servers are \*\*authorized to send emails on behalf of your domain. _These authentication mechanisms help validate the legitimacy of emails sent from your domain, including Google Calendar invites_.

## 3\. Safelisting Google’s IP Addresses

If your [DMARC policy](https://dmarcreport.com/dmarc-policy/) is set to quarantine or reject emails that fail authentication checks, consider safelisting [Google’s IP addresses](https://www.lifewire.com/what-is-the-ip-address-of-google-818153) to ensure that legitimate Google [Calendar invites](https://www.scmagazine.com/news/accepting-a-calendar-invite-in-outlook-could-leak-your-password) sent from Google’s servers are not inadvertently **blocked or marked as spam**.

![Dmarc analyzer](https://media.mailhop.org/dmarcreport/images/2024/05/dmarc-analyzer-7.jpg) 

## 4\. Set up DMARC Policy

_Configure a suitable DMARC policy for your domain to specify how receiving email servers should manage emails that fail DMARC checks_. We suggest that you begin with a **monitoring policy** (p=none) to keep an eye on [DMARC alignment](https://dmarcreport.com/blog/what-is-dmarc-alignment-and-how-does-it-work/) without impacting email delivery.

Once you’ve analyzed the results and ensured legitimate emails are passing DMARC checks, consider moving to an **enforcement policy** ([p=quarantine or p=reject](https://dmarcreport.com/blog/dmarc-enforcement-timeline-none-to-reject-roadmap/)).

## 5\. Monitor DMARC Reports

Choose to receive [DMARC aggregate (RUA) reports](https://dmarcreport.com/dmarc-aggregate-reports/) and [DMARC forensic (RUF) reports](https://dmarcreport.com/dmarc-forensic-report/) in your [DMARC record](https://dmarcreport.com/blog/how-to-create-dmarc-record-stop-email-spoofing-domain/) and regularly monitor them to \*\*spot issues and anomalies related to Google Calendar invite emails . These reports help you with valuable insights into [email authentication](https://dmarcreport.com/blog/why-email-security-matters-and-how-to-get-it-right/) failures, enabling you to adjust your DMARC policy and authentication mechanisms as and when required.
