DMARC improves it by working with SPF and DKIM to authenticate sending sources and instruct receivers what to do with failures. Deliverability suffers when phishing volume rises, ISP filters tighten, and recipients lose trust in unverified senders. DMARC counters this five ways: it blocks spoofed mail that would damage sender reputation, it signals legitimacy to ESPs so they trust your domain, it enables BIMI so your logo displays in supported clients, it provides aggregate reports identifying authentication failures and unauthorized senders, and it reduces false positives by aligning the visible From domain with authenticated sending sources. The result is more legitimate mail in the primary inbox and fewer rejections. How does DMARC improve email deliverability? Your browser does not support the audio element.

From running marketing campaigns to offering customer support, from notifying customers with transactional details to engaging them **one-on-one** with newsletters and emails, they do it all for your business. But what if these emails do not reach your audience at all? Poor email deliverability can not only affect your **day-to-day business operations** but also tarnish your [brand reputation](https://netreputation.com/). This is exactly why you need [DMARC](https://dmarcreport.com/what-is-dmarc/) to enhance your email deliverability. **Let’s find out** how your email deliverability is dependent on DMARC. ## What is email deliverability, and why does it matter? The ability of an email to reach the primary inboxes of your recipients is known as email deliverability. When you send an email to an intended recipient and it reaches the **mailbox provider’s gateway server**, it is considered “delivered.” But [email deliverability](/a-guide-on-email-deliverability) is about the part that comes after this. Once your email has reached the mailbox provider’s gateway, it must overcome several hurdles, such as passing security checks, failing which can result in blocklisting, rejection, or being flagged. [![mailbox provider’s ](https://media.mailhop.org/duocircle/images/2025/07/spf-record-checker-1223.jpg)](https://media.mailhop.org/duocircle/images/2025/07/spf-record-checker-1223.jpg) Here’s why email deliverability should be one of your top concerns: ### 1\. Effective mode of communication _Emails still top the chart as a primary mode of communication even in the age of WhatsApp, Slack, and other communication platforms_. When you send out an email, you expect it to be seen and acted upon accordingly. That’s precisely why you should **aim for high deliverability**. ### 2\. Brand reputation If your emails are landing in the [spam folders](https://cybernews.com/news/microsofts-breach-notification-emails-end-up-in-spam-folder/) of your customers, it can badly hamper your brand reputation. Your audience will be **highly sceptical** about your brand credibility if they find almost all your emails in their spam folder. ### 3\. ROI on email marketing campaigns [Email marketing](https://www.coursera.org/in/articles/email-marketing), if done right, can effectively boost the conversion rates for your business. But for that, your emails must land successfully in the **primary inbox of your customers**. If your emails are not consistently landing in the spam or promotions folder, it is practically impossible to get those conversions and engagements. [![spam or promotions folder](https://media.mailhop.org/duocircle/images/2025/07/spf-record-1223.jpg)](https://media.mailhop.org/duocircle/images/2025/07/spf-record-1223.jpg) ### 4\. Transactional delivery notifications _Imagine this! One of your new customers has just checked out and made the payment_. Now they are waiting for that confirmation email from you. But if your email doesn’t reach them, that too, within a few minutes, they will start doubting your brand. ### 5\. Customer support system If your **customer support emails** are not landing in the primary inbox of an audience who has raised an issue or needs help with something specific, your brand loses that “Customer-friendly” or “easily approachable” tag. ## Email deliverability challenges in 2025 Your email deliverability gets affected by the following factors. Have a look! [![ email deliverability](https://media.mailhop.org/duocircle/images/2025/07/sender-policy-framework-1223.jpg)](https://media.mailhop.org/duocircle/images/2025/07/sender-policy-framework-1223.jpg) ### Excessive email fraud [Phishing and spoofing attacks](https://www.msspalert.com/brief/novel-usps-spoofing-phishing-attack-relies-on-malicious-pdfs), BEC, and other similar email-centric [cyber frauds](https://www.securitymagazine.com/articles/101523-90-of-us-companies-faced-cyber-fraud-in-2024) are on the rise. [Threat actors](https://www.cybersecuritydive.com/news/threat-actors-uk-retail-attacks-targeting-us/748198/) frequently exploit legitimate domains to send malicious emails to unsuspecting recipients. This badly hampers the brand reputation. ### Rigid ISP filters The increasing number of [cyberattacks](https://www.securitymagazine.com/articles/101596-cyberattacks-targeting-us-increased-by-136) on the **email ecosystem** has led to the strict implementation of filtering mechanisms. Email Service Providers have become way more strict with the filtering tools, which sometimes leads to your genuine emails being flagged or rejected. ### Complicated email infrastructure Businesses prefer using different **third-party tools** for running email campaigns. This often poses a problem to consistent email deliverability. ### Doubts and suspicions among users Your audience is well aware of the rising threat of cyberattacks. This has a direct impact on your brand credibility. They can get sceptical about your emails, which will gradually reduce the **open rates and engagement** of your emails. ## How does DMARC boost email deliverability? DMARC helps you achieve the perfect balance between [email security](/) and deliverability. Here’s how: ### Fool-proof protection against phishing and spoofing attacks DMARC works in conjunction with [DKIM](/resources/what-is-dkim) and [SPF](https://autospf.com/blog/spf-guide-understanding-sender-policy-framework/) to help prevent malicious emails from reaching your primary inbox. _Emails that fail authentication checks simply get rejected or land in the spam folder_. Thus, only genuine **emails reach your audience**. In the long run, this results in improved email deliverability. [![malicious emails](https://media.mailhop.org/duocircle/images/2025/07/spf-record-check-1223.jpg)](https://media.mailhop.org/duocircle/images/2025/07/spf-record-check-1223.jpg) ### Winning your ESP’s trust ESPs trust domains that use DMARC to **authenticate their emails**. They are highly likely to deliver your emails to your audience now, thereby improving the deliverability. ### Improved brand identity and image DMARC deployment enables you to use a feature called [BIMI](/resources/what-is-bimi) or Brand Indicators for Message Identification). BIMI-enabled emails display your brand logo in your email, thereby establishing trust and enhancing your brand image among your audience. ### Consistent feedback and improvement DMARC provides detailed reports that help you identify and rectify any ongoing deliverability issues for a **better deliverability experience**. [![DMARC’s Detailed Reporting](https://media.mailhop.org/duocircle/images/2025/07/email-sending-services-2353.jpg)](https://media.mailhop.org/duocircle/images/2025/07/email-sending-services-2353.jpg) ### Reduced false-positive instances DMARC implementation reduces the chance of your genuine emails getting flagged or rejected by [email service providers](https://www.activecampaign.com/glossary/email-service-provider). ## Final thoughts If your ongoing [email campaigns](https://www.campaignmonitor.com/resources/glossary/email-campaign/) are not delivering the expected ROI, despite your best efforts, or your [email communications](https://www.tidio.com/blog/email-communication/) are falling flat, then it is highly likely that your emails are not reaching the intended audience. _It’s high time to opt for DMARC enforcement and boost your email deliverability_.
