DKIM & DMARC Records

When you send an email, you want to make sure it is safe and trusted. Two important tools that help with this are DKIM and DMARC. These tools protect emails from being tampered with or sent by bad actors pretending to be someone else.

Make Your emails More Trusted by Email Providers

These records boost email security, prevent phishing scams and highly increase the deliverability to your recipients' inboxes.

Get Your Emails Whitelisted by Google & Yahoo

DKIM adds a digital signature, proving the email is authentic, while DMARC ensures emails that fail checks are flagged or blocked.

So What is This Exactly?

This is a way to whitelist your emails so they have a better chance of landing in the inbox instead of the spam folder. Your emails are seen by Google, Yahoo and other email providers as more trusted when these records are added to your domain email. Let’s break down how they work.

DKIM (DomainKeys Identified Mail)

A Domain Keys Identified Mail (DKIM) record is an email authentication tool. Adding it to your business email verifies that your email was sent from a reliable, trustworthy source and was not modified en route to your recipients. DKIM adds a digital signature to emails sent from a domain. Think of it like a special seal or stamp that proves the email really came from the right place. When an email is sent, DKIM uses a private key to create this signature. The recipient’s email server then checks the public key, stored in the sending domain’s DNS, to verify if the message was signed correctly. If the email has been changed or faked along the way, the signature won’t match, and the email can be flagged as suspicious.

DMARC (Domain-based Message Authentication, Reporting, and Conformance)

DMARC works together with DKIM and SPF (another email authentication tool). It tells email providers how to handle messages that fail DKIM or SPF checks. DMARC policies can do three things:

None – Just report if emails fail authentication, but don’t block them.
Quarantine – Put failed emails in the spam or junk folder.
Reject – Block emails that don’t pass the checks.

DMARC also sends reports back to the domain owner, showing which messages passed or failed the checks. This helps organizations understand if someone is trying to misuse their email domain.

Why These Tools Matter

DKIM and DMARC are important because they prevent phishing and spoofing attacks. Phishing is when someone pretends to be someone else to trick people into giving personal information. Spoofing is when a scammer fakes an email address to look trustworthy.

By using DKIM and DMARC, email senders and receivers can make sure messages are real and not tampered with. Companies that set up these tools can protect their brand and customers from scams.

In summary, DKIM adds a signature to emails to prove they are legitimate, while DMARC ensures email systems know how to handle messages that don’t pass checks. Together, these tools help keep email safe and secure.
