Sendmarc Email Security

Sendmarc - Email Security Platform

Secure your domain against email impersonation, phishing, and spoofing with automated, and powerful DMARC, DKIM, and SPF control. 

Sendmarc’s DMARC solution enables you to manage any number of domains and protect them from abuse and the sending of fake emails.

The Email Problem

96% of phishing attacks arrive via email, highlighting that this popular communication method still poses an immense security threat to organizations. 

A historical email flaw means that cybercriminals can impersonate almost any domain and deliver fake emails to inboxes on your behalf. This causes business damage and impacts the deliverability of the emails you send. Sendmarc mitigates this flaw by ensuring your brand’s domain is secured with DMARC protection.

You must ensure that your email security prevents the potential financial and reputational damages caused by phishing, spoofing, and other impersonation attacks using your company’s domain.

The Sendmarc Solution

Sendmarc uses DMARC to take organisations to full protection against impersonation and spoofing attacks within a maximum of 90 days. This leading email security provider is designed to enable DMARC compliance quickly and seamlessly for organizations of any size.

Using DMARC

Domain-based Message Authentication, Reporting and Conformance (DMARC) lets you decide which messages get accepted and lets you see who is using your domain.

What is DMARC?

DMARC, which stands for Domain-based Message Authentication, Reporting, and Conformance, is an email authentication protocol that helps protect email domains from spoofing, phishing, and other types of abuse. DMARC builds on two existing protocols, SPF (Sender Policy Framework) and DKIM (DomainKeys Identified Mail), to verify the identity of the sender and the integrity of the message. 

DMARC also provides a way for email receivers to report back to the senders about the status of the messages they receive, such as whether they pass or fail the authentication checks, or whether they are rejected, quarantined, or delivered.

How does DMARC work?

DMARC works by adding a special TXT record to the DNS (Domain Name System) of the email domain, which specifies how the domain owner wants the receivers to handle the messages that claim to come from that domain. 

The TXT record contains a set of tags and values that define the DMARC policy, such as the alignment mode, the percentage of messages to apply the policy to, the reporting options, and the desired actions for failed messages. 

When a receiver gets an email from a domain that has a DMARC record, it first checks if the message has a valid SPF and DKIM signature, and then compares the domains used in those signatures with the domain in the From header of the message. 

If the domains match, or align, according to the DMARC policy, the message passes the authentication. If not, the message fails the authentication and the receiver follows the action specified by the DMARC policy, such as reject, quarantine, or none.
