What is a DMARC Monitoring Service?

DMARC is one of the main protocols used to authenticate if emails are genuine. Senders use it to combat email spoofing. This is when spammers and phishers try to use your email domain fraudulently to send fake emails. Falling victim to spoofing can be devastating for your sender reputation. So authentication is important for maintaining good email deliverability.

DMARC gives mailboxes instructions based on analysis of two other authentication protocols, SPF and DKIM. Every email address has a domain, the part after the @ sign. It’s easy to start using an email domain you don’t own fraudulently. But SPF and DKIM records authenticate genuine addresses that belong to a domain.

If SPF and DKIM records don’t check out, that suggests an email address is fake. DMARC then steps in to tell the mailbox what to do. Either block the email or quarantine it for further inspection. These instructions are called a DMARC policy. 

DMARC policies can also include instructions to report on blocked or quarantined emails. This is important because failed authentication doesn’t always mean a fake address. It could be that you haven’t kept up with your DKIM and SPF records. A DMARC report lets you check this.

The only problem is, DMARC reports are XML data feeds. They’re called DMARC aggregate reports. And they’re meant for machines. So this is where a DMARC monitoring service comes in. It turns the raw data of a DMARC report into something intelligible and usable. This is how you get details about blocked and quarantined emails. And armed with that insight, you can do something about it.

9 Best DMARC Monitoring Services Reviewed in 2026

Bouncer

Bouncer is an all-round email deliverability service. It’s best known for email verification. You can use it to check email addresses are genuine and working before you hit send. This reduces bounces and improves your sender reputation. It uses multiple tools to verify emails. Some, like DNS and MX record checks, are closely related to DMARC monitoring.

Bouncer also has an inbox placement testing tool called the Deliverability Kit. Inbox placement testing measures how many emails are landing in inboxes. But tests also incorporate blocklist monitoring and authentication checks. So for every non-delivered email in a test, you can look up the causes.

This integrated approach is Bouncer’s strength as a deliverability service. Inbox placement testing, blocklist checks and DMARC monitoring sometimes come separately. The fact that they all feed into one deliverability test is very user-friendly. Plus, Bouncer’s email validation system supports better DMARC results. Bouncer’s verification tools include automatic list cleaning, removing fake and failed addresses. Cleaned lists mean fewer authentication failures.

Bouncer’s Deliverability Kit starts at $25 a month for 250 test emails. This covers 10 IP addresses and domains for monitoring. Email verification starts at $8 for 1000 emails. Or you can get $2 off by going for a monthly plan. You get 100 verification credits for free.

Many of EasyDMARC’s authentication tools are available for free for quick checks. They include DMARC, SPF and DKIM record checkers and generators. A DNS record checker, domain scanner and reputation monitor. There is also a useful free plan. At the opposite end of the scale, EasyDMARC also offers managed authentication services.

EasyDMARC has a sister product called EasySender. This includes an email verification tool and inbox placement testing. Both are priced separately. And inbox placement testing in particular is pricey.

ZeroBounce

ZeroBounce is an email deliverability platform. It starts with email validation. But it also has inbox placement and server testing. Blacklist monitoring. IP warm-up. And DMARC monitoring. There are also email finder tools thrown in, too.

For DMARC monitoring, ZeroBounce lets you register multiple domains. Configuration is simple via a user-friendly wizard. Once set up, ZeroBounce doesn’t impose any email limits. It monitors DMARC reports for every email you send from each connected domain. You get domain-by-domain performance reports.

This diagnoses issues with sending servers.

The ZeroBounce ONE plan starts at $99 a month. This includes 1 domain for DMARC monitoring and 25K email validation credits. There’s a free plan that includes 100 email verification checks a month, but doesn’t have DMARC monitoring.

Postmark Free DMARC Monitor

Postmark is a transactional email service owned by email marketing automation specialist ActiveCampaign. It offers a dedicated sending infrastructure via email API and SMTP servers.

Postmark also runs a DMARC monitoring tool as an add-on. I’d rate this as one of the most user-friendly DMARC tools around. You provide a domain to monitor. And Postmark sends you weekly emails with easily digestible DMARC reports. Postmark runs checks against all sending sources and IP addresses associated with your domain. And then gives a simple breakdown of how many emails passed SPF and DKIM for each source. 

Postmark’s DMARC monitoring tool is available for free and as a paid-for premium version. The free tool reports on the top 10 mail sources and top 5 IP addresses for each domain only. The paid version reports on all sources. The premium version also has a web dashboard for results.

The Postmark DMARC monitor is free to use. But the free version monitors only select email sources and IPs. To get unlimited monitoring for all your domains, the paid version costs $14 a month.

Valimail

Valimail specializes in DMARC authentication. It has two standout USPs. One, it offers a DMARC monitoring service for free. And two, you can move from monitoring to stopping spoofing and phishing attacks. Making sure your whole sending set-up is compliant with popular mailbox providers.

Valimail’s DMARC monitoring tool tracks all sending services associated with your domain. It identifies all servers and IP addresses by name. So you get full visibility about the third-party sending services used in your chain. This lets you pinpoint where authentication failures are happening. It also identifies where unauthorized emails are being sent from. This is a big plus for larger organizations at high risk of spoofing attacks.

Those organizations can then use Valimail’s Enforce tool to stop the spoofing. This automates the whole authentication process. From configuring SPF and DKIM records to authorizing the sending services. Again, this is mainly aimed at bigger businesses with complex global sending requirements.

Another option to improve authentication and deliverability is the Align tool. This configures your sending services for Gmail, Outlook, and Yahoo! Authentication. Again, it’s all automated. And provides a simpler approach to improving authentication that might appeal to marketers.

Valimail’s Align tool starts at $19 a month. This configures authentication for 500,000 emails. Valimail provides custom pricing on application for its Enforce tool. But costs start at around $2,000 a year. 

PowerDMARC

PowerDMARC combines DMARC analysis with hosted authentication services. Its analytics platform transforms raw DMARC reporting data into an impressive visual dashboard. This breaks DMARC performance down into eight different views. Including percentages of your emails that align with and pass DMARC, DKIM, and SPF. A full list of performance by sending services and IP addresses. A geographical breakdown of authentication failures. And AI analysis of the IP addresses posing the biggest spoofing risks. If you think your IP is causing deliverability issues, check out the best IP reputation checkers.

PowerDMARC’s hosted service provides a simple interface for authentication management. You can choose to configure and monitor DMARC, SPF, and DKIM separately.

DMARC Advisor

DMARC Advisor is a DMARC analyzer. It makes raw DMARC XML data accessible via a visual dashboard. It also provides real-time reporting for authentication incidents. And lets you manage DNS configuration in the same place as your monitoring.

DMARC Advisor’s dashboard is impressive for its combination of detail and accessibility. There’s an overview of every connected domain. Summarizing DMARC, DKIM, and SPF status by sender service and IP address. There’s a detailed breakdown of authentication by sending source used in the past 7 days. And you can dig down into the details of trends over time. Including looking at patterns in where and when threats are detected. 

The reporting tool also identifies and flags up suspicious subdomains. And sends alerts for spoofs, non-compliant users, and authentication failures.

Conclusion: DMARC Monitoring

A DMARC monitoring service is a smart move if you want to improve your email deliverability. Especially if your sender reputation seems to be taking a dive. And you suspect gaps in your email authentication are causing the issues. Either because you’re getting spoofed. Or you’re just not on top of your DKIM and SPF records.

I’d always go for an all-round deliverability service that includes DMARC monitoring. You get more for your money. Combined tools and protections will have a bigger impact on deliverability. That said, standalone DMARC tools can be useful. Especially if you’re a large-scale sender with a big, complex sending infrastructure.

So to round things off, my DMARC monitoring service recommendations are as follows:

• Best all-round deliverability platform: Bouncer
• Best for standalone DMARC monitoring: PowerDMARC
• Best for stopping spoofing: Valimail
• Best free DMARC tool: Postmark
