[ Check DMARC Record → ](/tools/dmarc-checker/) 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. 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. Even [Google and Yahoo have mandated the implementation of DMARC](https://dmarcreport.com/blog/google-and-yahoos-new-email-authentication-policy-for-2024/) for companies sending over 5,000 emails per day . However, many companies are yet to take [DMARC adoption](https://dmarcreport.com/blog/dmarc-adoption-amongst-us-education-sector/) seriously; unfortunately, the myths lurking around this topic put them into a dilemma, and hackers very well know how to take advantage of **email-based security loopholes**. But, as they say, it’s never too late to start- so here we are bursting common myths about DMARC to push you to get started. > The most common mistake we see during DMARC setup is jumping straight to p=reject without monitoring first, says Vasile Diaconu, Operations Lead at DuoCircle. Start at p=none, analyze your reports for at least a full quarter - you need to catch monthly, quarterly, and annual email senders that only fire periodically. Then fix any legitimate senders that fail before enforcing. We walk every customer through this sequence. ## Why Companies Refrain From Implementing DMARC? The DMARC world is still growing. You would be surprised to know that even by 2023 not all of the Fortune 500 companies have adopted DMARC. [12% or 60 companies](https://www.digitalinformationworld.com/2023/07/the-alarming-state-of-email-security.html#google%5Fvignette) are yet to be shielded by [DMARC policies](https://dmarcreport.com/dmarc-policy/). Moreover, what’s worse is that even the ones that have DMARC in place use the ‘none’ or ‘monitoring’ policy, which is almost equivalent to a domain without DMARC protection. Here are possible myths barring them from being a \*\*DMARC-compliant domain owner. As of 2025, DMARC is mandatory under multiple compliance frameworks. [CISA BOD 18-01](https://www.cisa.gov/news-events/directives/bod-18-01) requires p=reject for US federal domains. [PCI DSS v4.0](https://www.pcisecuritystandards.org/) mandates DMARC for organizations processing payment card data as of March 2025\. Google and Yahoo require DMARC for bulk senders (5,000+ messages/day) since February 2024, and [Microsoft began rejecting](https://learn.microsoft.com/en-us/defender-office-365/email-authentication-dmarc-configure) non-compliant email in May 2025\. The UK [NCSC](https://www.ncsc.gov.uk/collection/email-security-and-anti-spoofing), Australia’s [ASD](https://www.cyber.gov.au/resources-business-and-government/essential-cyber-security/ism/cyber-security-guidelines/guidelines-email), and Canada’s [CCCS](https://www.cyber.gc.ca/en/guidance/implementation-guidance-email-domain-protection) all mandate DMARC for government domains. Cyber insurers increasingly require DMARC enforcement as an underwriting condition. ## 1\. SPF and DKIM are Enough Owners of domains that are already compliant with [SPF](https://dmarcreport.com/what-is-spf/) and DKIM disapprove of the additional security strengths that come with DMARC. Little do they know that DMARC is a reliable gateway for making decisions about an **email sender’s legitimacy**. Yes, SPF and DKIM have their own sets of benefits, but when combined with DMARC, the trio rules the [email security](https://dmarcreport.com/blog/why-email-security-matters-and-how-to-get-it-right/) world and keeps phishing attacks at bay. ## 2\. We are Office 365 or Google Workspace Users, and these Platforms Claim to Support DMARC Office 365 or [Google Workspace](https://dmarcreport.com/blog/dmarc-google-workspace-gmail-setup-2026/) are capable of examining \*\*inbound emails \*\*of DMARC authentication, but what about receiving and [analyzing DMARC reports](https://dmarcreport.com/tools/dmarc-report-analyzer/)? Neither of these platforms sends reports, and without studying these reports, there’s no benefit of implementing DMARC. [DMARC Forensic and aggregate reports](https://dmarcreport.com/blog/why-is-rua-important-for-monitoring-email-authentication-issues/) inform you about how your email domain is getting used and if a malicious entity is trying to infiltrate the system. _This helps you adjust DMARC policies and their implementation percentages_. Not only this but by relying only on Office 365’s and Google Workspace’s protection, you will lose the benefit of knowing if any cloud or on-premise services are sending \*\*unauthorized messages by impersonating you or someone from your company. ![Dmarc record](https://media.mailhop.org/dmarcreport/images/2023/12/dmarc-record-12.jpg) ## 3\. DMARC Would Affect the Email-Marketing ROI Instances of [false positives](https://www.digitalinformationworld.com/2023/11/google-enhances-gmails-spam-defense.html) are common for DMARC-compliant domains that are not monitored and maintained regularly and effectively. Companies insisting general IT experts (who are not proficient and specialized in handling SPF, [DKIM](https://dmarcreport.com/what-is-dkim/), and DMARC) to set up and monitor DMARC should ditch this approach and instead onboard a specialist or outsource the responsibility to **cybersecurity agencies**. _When appropriately validated, DMARC significantly improves the likelihood of successful delivery of your marketing emails_. However, a potential issue arises when implementing DMARC without prior identification and authentication of all marketing correspondence. This can lead to the accidental \*\*quarantine or rejection of legitimate marketing emails if a [DMARC enforcement](https://dmarcreport.com/blog/dmarc-enforcement-timeline-none-to-reject-roadmap/) policy is activated. ## 4\. It Takes Months to Set up DMARC Manually setting up DMARC can definitely take weeks, if not months, but how about you switch to automatic tools? There are several online [DMARC record generators](https://dmarcreport.com/tools/dmarc-record-generator/) where you just have to fill-in a few details like policy, [DMARC aggregate report](https://dmarcreport.com/dmarc-aggregate-reports/) email, **forensic feedback email**, [SPF and DKIM alignment](https://dmarcreport.com/blog/what-is-dmarc-alignment-and-how-does-it-work/), etc. That’s it, and you will receive a [DMARC record](https://dmarcreport.com/dmarc-record/)instantaneously . ## 5\. Staying Under the SPF Lookup Limit is Challenging Being within the maximum lookup limit of 10 is challenging, especially for large enterprises. But using tools like [AutoSPF](https://autospf.com/)’s automatic [SPF flattener](https://dmarcreport.com/blog/fix-spf-permerror-overcome-too-many-dns-lookups/) sorts out things for you. Such tools automatically flatten and compress all domains within an [SPF record](https://dmarcreport.com/tools/spf-record-generator/), which subsequently kills the need for frequent [DNS lookups](https://dmarcreport.com/blog/fix-spf-permerror-overcome-too-many-dns-lookups/). This helps you improve your **domain’s email deliverability**, ensuring all the legitimate messages get placed in the primary inboxes of recipients instead of getting [marked as spam](https://help.pointerpro.com/en/support/solutions/articles/35000041542-how-do-i-avoid-my-emails-being-marked-as-spam-) or rejected. ## 6\. p=none is Better Than No DMARC At All p=none means all legitimate and illegitimate messages will be placed in the inboxes. However, domain owners will receive reports for messages that fail SPF and/or [DKIM authentication checks](https://dmarcreport.com/blog/how-to-check-if-your-email-authentication-is-set-up-correctly-for-dkim-dmarc-spf-bimi/). So, do you think there’s any difference with respect to email security? No, right? [Threat actors can still make successful phishing attempts](https://unit42.paloaltonetworks.com/two-campaigns-by-north-korea-bad-actors-target-job-hunters/?web%5Fview=true)**,** damage your **business reputation**, or make you liable to litigations. \*\*p=none policy is called the ‘monitoring’ policy because it’s only meant for _monitoring_ your domain’s \*\*email-sending activities for a while before you switch to a stricter policy. The relaxed policy has no capability to stop [suspicious emails from being placed in the inbox folders](https://www.chroniclelive.co.uk/news/uk-news/outlook-gmail-email-warning-scam-26317232). You must aim to reach a policy of quarantine or reject at **100%** to reap the highest benefits of DMARC adoption . ## 7\. DMARC Reports Are Difficult to Understand Well, it’s not a myth that [DMARC reports](https://dmarcreport.com/blog/how-to-read-dmarc-reports-guide-2026/) are complex and difficult to comprehend, but there’s a simple solution to this problem. All you have to do is use a tool that parses the complicated XML reports into simple language. [DMARC forensic reports](https://dmarcreport.com/dmarc-forensic-report/) serve a dual purpose by aiding in the resolution of authentication issues within legitimate email flows and detecting the origins of [malicious emails](https://timesofindia.indiatimes.com/gadgets-news/malicious-emails-sit-for-around-83-hours-in-employees-inbox-before-being-noticed-report/articleshow/83241166.cms). ![Dmarc record](https://media.mailhop.org/dmarcreport/images/2023/12/dmarc-record-6571.jpg) ## 8\. SPF Management is Complicated and Resource Consuming Keep a few points in mind to overcome this challenge- - Don’t miss out on enlisting any valid sending source. - Update removal or addition of sending sources. - Use \*\*SPF flattening tools to avoid exceeding the lookup limit. - Avoid the use of mx and ptr mechanisms . - Remove the references to domains and ‘include’ domains that are no longer in use. - It’s suggested to use SPF for subdomains as well. - Extra ‘+’ symbol in ‘include’ - _Ensure the character string never exceeds the limit of 255 characters_. ## Myths Debunked! Now Take A Step Forward [DMARC](https://dmarcreport.com/) is extremely important for the \*\*protection of domains and businesses. _With that said, we humbly compel you to take the first step toward DMARC adoption, especially if you use Google or Yahoo to send emails_. This digital world is becoming a playground for hackers, but we must level up our \*\*security protocols and defeat them.
