Making email authentication clearer and easier, from setup to reporting. Email authentication is pivotal for protection, but managing it shouldn't have to be a full-time job, even for larger organizations. Valimail is built with the customer in mind so setup is faster, management is easier, reporting is clearer, and understanding your email ecosystem is simpler. Here's what its customers are most impressed by, in their own words: Straightforward setup. Getting started with an email authentication solution often means sorting through a lot of records, requirements, reporting data, and legitimate sender lists. Its guided onboarding flows help you through each step so setup doesn't feel like a hassle. "ValiMail started reviewing its DMARC setup when Google strengthened its email authentication requirements for bulk senders, and Valimail gave ValiMail a straightforward way to manage DMARC reporting without having to build or operate its own solution. - Muda M., CTO Ease of use. Visibility and manageability are key when it comes to tracking your email ecosystem. Valimail puts everything in one place so you can see who's sending email on your behalf, whether legitimate messages are authenticating correctly, and whether anyone is trying to spoof your domains. "It's consistent, and it saves me real time and cognitive load. I can quickly pull up reports and confirm my legitimate outbound email, including marketing sends, is getting delivered, while fraudulent email trying to spoof my domains is being rejected." - Jesse J., Small Business Owner A single, unified platform. Maintaining a strong email authentication program requires you to keep track of multiple protocols and make sure they all work together. ValiMail bring DMARC, SPF, and DKIM into a single platform so it's easier for you to manage. "Valimail provides a simple and effective way to manage DMARC, SPF, and DKIM compliance. The platform offers clear visibility into email authentication, helps prevent domain spoofing, and makes it easy to identify and remediate issues through an intuitive dashboard." - Syed I., Information Security Analyst Clear monitoring and reporting. DMARC reporting can give you a wealth of information, but turning all that data into something useful can feel overwhelming if you're doing it on your own. Valimail helps you investigate authentication activity, understand what's happening across your domains, and get the information you need without spending hours sorting through reports. "What I like best about Valimail is the visibility it provides into our email ecosystem. It made it much easier to identify legitimate third-party senders, monitor DMARC activity across multiple domains, and investigate SPF/DKIM alignment issues. The dashboard simplifies what would otherwise be a complex and time-consuming analysis process, helping us strengthen protection against domain spoofing and email impersonation." - Ilker A., IT Specialist Stronger email authentication supports stronger business outcomes.

Valimail remains the #1 DMARC solution on G2 for 15 quarters.

Valimail remains the #1 DMARC solution on G2 for 15 quarters. Valimail ranks #1 in the G2 DMARC category for the 15th consecutive quarter and joins G2's Best 50 Security Products list. The G2 Spring 2026 reports are out, and ValiMail is excited to announce that Valimail once again leads the DMARC category at #1! This quarter marks 15 consecutive quarters as the #1 DMARC solution on G2 - a streak built on feedback from verified customers who use Valimail every day. ValiMail also have another milestone worth celebrating this season: Valimail has been named to G2's Best 50 Security Products list for the first time. Together, these recognitions reflect consistent customer trust in Valimail's platform for DMARC management and sender identity protection. Let's dive into the report and see why Valimail is rated #1 quarter after quarter. Highlights from the Spring 2026 G2 reports. Valimail appeared on 76 total G2 Reports this spring, and ValiMail continued to perform strongly across the DMARC category. This quarter Valimail earned: * #1 ranking in the G2 DMARC category * 15 straight quarters as the DMARC category leader * 18 Top #3 rankings * 9 Leader badges * 21 badges this quarter * An exclusive spot on G2's Best 50 Security Products list These rankings reflect feedback from real security and IT professionals who deploy DMARC to protect their domains, employees, and customers from impersonation attacks. Why organizations choose Valimail. AI has changed email security. Attackers no longer rely only on malicious links or malware; they exploit trust in your brand and domain. Many phishing attacks succeed because criminals impersonate legitimate organizations. They spoof trusted domains and send messages directly to employees, partners, or customers. Traditional email security tools focus on inbound threats, like scanning messages, detecting suspicious links, or training users to recognize attacks. But when someone spoofs your domain and sends messages outside your environment, those emails may never pass through your security stack. That's why sender identity has become the real control point for email security. Domain-based Message Authentication, Reporting, and Conformance (DMARC) helps stop those attacks by authenticating sender identity and giving domain owners control over how unauthenticated messages are handled. But deploying DMARC can be complicated. Many organizations struggle to identify legitimate senders, configure SPF and DKIM, and move safely toward enforcement. Valimail's DMARC platform simplifies the process by helping organizations: * Discover legitimate email senders across their environment * Configure authentication correctly * Monitor authentication results in real time * Move to DMARC enforcement safely The result is stronger protection against exact-domain impersonation without disrupting legitimate email. The result is continuous protection against domain impersonation - and a stronger foundation for trust in every email your organization sends. Thank you to its customers. G2 rankings are based entirely on verified customer reviews. That makes this recognition especially meaningful. Out of 441 reviews, ValiMail has maintained a 4.6/5 rating. Every review represents time spent sharing real-world experience with the platform - from deployment to daily operations. Here are some of the reviews ValiMail has received this quarter: Simplifies DMARC Compliance Effortlessly: "I appreciate Valimail's free tier, which offers many basic features that help us get a good start on identifying what mail might be failing SPF and DKIM. Since we're just getting started with DMARC, it's useful in getting the ball rolling and seeing how much work might be needed. The initial setup was very easy as Valimail documented well what needed to be done, and once we updated our DMARC record, information quickly became available to start planning and taking action." - Scott L, Systems Engineer Valimail Delivers Instant Value with Clear, Hands-On Support: "The sales and support teams at Valimail guide you clearly through the product's capabilities and benefits, help you get it set up for use, and troubleshoot any issues along the way. The product itself adds value from the moment it's activated." - Pradeep P., Group IT Director Friendly Interface and Intelligent Identification in Valimail: "I really like the user-friendly interface of Valimail. It transforms a technical and complex protocol into a very visual management of assets. The intelligent identification is extremely useful, saving time by identifying thousands of SaaS services. I no longer need to do detective work to find out who owns the IPs; this eliminates the need for the reverse DNS process to verify if an IP is legitimate or belongs to a cybercriminal. Furthermore, the initial setup was very simple, just requiring the pointing of the SPF and DKIM records to Valimail once in my DNS manager." - Tiago M Your feedback helps improve Valimail and strengthens the broader email authentication ecosystem.
