DMARC: What's It And Why Do You Want It?
DMARC (Domain-based Message Authentication, Reporting & Conformance) is a standard that prevents spammers from utilizing your domain to send email without your permission — also known as spoofing. Spammers can forge the "From" address on messages so the spam seems to return from a user in your domain. An excellent example of this is PayPal spoofing, the place a spammer sends a fraudulent email to you pretending to be PayPal in an effort to acquire your account information. DMARC ensures these fraudulent emails get blocked before you even see them in your inbox. In addition, DMARC gives you nice visibility and reports into who is sending email on behalf of your domain, guaranteeing only legitimate e mail is received.
The nice news is that DMARC is open and free for anybody to use, allowing you to secure your domain’s emails and achieve control of your electronic mail delivery. All it's important to do is comply with the implementation steps in this guide and choose an ESP who supports DMARC.
What are the benefits of implementing DMARC?
DMARC is a key element of a brand‘s electronic mail security and deliverability strategy as it enables:
Visibility - Monitor emails sent using your domain to make sure they're properly authenticated utilizing SPF and/or DKIM.
Model Protection - Block spoofed messages which may damage your model‘s fame with customers.
Security - Forestall customers from falling victim to phishing scams that would compromise your organization‘s security.
Does DMARC improve deliverability?
DMARC permits you to see whether emails sent utilizing your domain are properly authenticated utilizing SPF and DKIM. This permits you to identify and fix any authentication points that may affect the deliverability of your emails.
Stopping spoofed emails from reaching customers can decrease spam complaints and protect your domain‘s reputation with ISPs.
How does DMARC work?
Before you understand the DMARC protocol, you first must understand two e-mail authentication standards called DKIM and SPF. DMARC is built on top of those standards, so let’s go over them first. In the event you already know about DKIM and SPF, skip to the DMARC section.
