DMARC Tags – Learn What they Are and Why You Need to Use Them

DMARC (Domain-based Message Authentication, Reporting & Conformance) is an **email authentication protocol that improves the SPF and DKIM protocols. It allows senders to specify how email should be handled if it fails SPF or DKIM authentication. This post discusses one of the most crucial aspects of DMARC, i.e., DMARC Tags.

DMARC is the only email authentication protocol that gives you both enforcement and visibility, says Brad Slavin, General Manager of DuoCircle. SPF and DKIM authenticate silently - DMARC tells you what happened and lets you control the outcome. That combination of reporting and policy is why DMARC adoption is accelerating.

DMARC (RFC 7489) ties SPF and DKIM together by requiring alignment between the envelope sender and the visible From header. According to Google’s February 2024 bulk sender requirements, a DMARC policy of at least p=none is now mandatory for any domain sending 5,000+ messages per day to Gmail users. DMARC provides a way for email providers to give feedback to the sender about whether or not their messages are being authenticated and delivered. This feedback can improve the sender’s email infrastructure and increase the chances of their messages being delivered to the inbox. One crucial aspect you need to know before implementing DMARC for your domain is DMARC Tags .

What are DMARC Tags? DMARC tags are a type of HTML tag used to help improve the deliverability of email messages. DMARC tags control how emails are handled when sent from one email system to another. They are also used to track an **email message’s route and identify its sender.

They are added to the email headers of messages and can help to ensure that the message is delivered to the intended recipient. DMARC tags can also help to improve the chances that the recipient will open and read the message.

What are the Different Types of DMARC Tags? There are a few different types of DMARC tags, each with its function. The most common tags are the **“p” tag and the “sp” tag. “p” tag: The “p” tag stands for “policy.” This tag tells the DMARC system the conditions when DMARC authentication fails.

There are three possible values for the “p” tag:

• **“none”: This value tells the DMARC system to take no action when DMARC authentication fails.

• **“quarantine”: This value tells the DMARC system to place email into quarantine, such as a spam folder or similar location when DMARC authentication fails into a spam folder or similar location.

• _“reject”: _This value tells the DMARC system to reject when DMARC authentication fails.

There are some other tags that you also need to know about. The “sp” tag stands for “subdomain policy” and is used to specify what actions should be taken for a specific subdomain. There are also “rua” and “ruf” tags, which are used to specify where reports should be sent, and “fo” tags, which are used to specify what actions should be taken if an email fails DMARC authentication and does not contain a “p” tag. A sample dmarc record containing tags looks like this:

**v=none; p=none; rua=youremail@domainname.com

How Can DMARC Tags Help Your Business? The DMARC tags can help your business in several ways. Primarily, they can help improve your **email deliverability rates by providing feedback to your email service provider about whether your emails are being delivered to the inbox.

Additionally, DMARC can help to protect your brand by reducing the chances of your emails being spoofed or phished**. Finally, DMARC can also provide valuable insights into your email campaigns’ performance, helping you optimize your email marketing efforts.

Why Should You Use DMARC Tags? There are several reasons why you should use DMARC tags. One reason is that they can help to improve email deliverability. Using DMARC tags, you can specify how email providers should handle emails that fail DMARC authentication. This can help to ensure that your emails are delivered to the intended recipient, and it can also help to reduce the chances of your emails being marked as spam.

Another reason to use DMARC tags is that they can help to protect your email reputation. If your emails are not properly authenticated, they may be more likely to be spam. This can damage your reputation with email providers and make it more difficult for your emails to get delivered.

How Can DMARC Tags Improve Email Deliverability? DMARC tags can improve email deliverability in the following ways:

• Increasing the chances that your email will be delivered to the intended recipient. This is because DMARC tags can help ensure that email is **not marked as spam by email providers.

• Preventing your email from being blocked by email providers or rejected by recipients.

• Improving the visibility of your email in recipients’ inboxes by helping to ensure that your email is not filtered into the spam folder.

How to Set up DMARC Tags? There are three main steps to setting up DMARC tags:

• You need to create a DMARC record for your domain. This record specifies what actions should be taken if an email from your domain fails DMARC authentication.

• You must publish the DMARC record in your domain’s DNS. This allows mail servers to **fetch the record and use it to determine how to handle mail from your domain.

• You need to configure your mail server to check for DMARC authentication and take the appropriate action if it fails.

**Final Words Creating a DMARC record is straightforward if you follow the right steps. You need to specify a few parameters, such as the email address to which you want failure reports to be sent and the action to take if an email is not delivered. In conclusion, DMARC is an important tag that can help improve your email deliverability and protect your email sender’s reputation.
